I watched a support level that I believed with certainty would hold break without hesitation, and I have felt the anger that follows when the market refuses to obey my rules. That anger was not the market’s fault; it was the direct result of beliefs that demanded the market behave a certain way.
Replacing those demands with a single probabilistic conviction that my edge, over a large enough series, has a positive expectancy transformed not just my trading results, yet my entire emotional experience of the market this article explains every belief I had to dismantle and the one belief I put in their place, so you can stop fighting randomness and start working with it.
The Dangerous Belief That the Market Should Do Something
I spent years holding beliefs that the market should respect a support level, should reverse after a known pattern, should let me recover a loss. Every one of those beliefs crashed against the reality that the market does not owe me anything a probabilistic mind lets go of the word “should” entirely, accepting that price can do anything at any time without breaking a rule. This first section dismantles the false expectations that keep a trader trapped in frustration.
The word “should” is a signal that I am imposing my will on a system that has no will of its own. Every time I said the market should do something, I was making a demand that the market never agreed to. The market is not a person with obligations; it is a random system that distributes outcomes according to probability my demands were irrelevant, and the frustration they generated was entirely self‑inflicted. Letting go of “should” was not a compromise; it was an alignment with reality and the foundational identity shift from gambler to probability trader.
Why “Should” Is the Most Harmful Word in a Trader’s Vocabulary
Every time I told myself the market should behave a certain way, I set myself up for emotional punishment when it did not. The market has no obligation to respect my analysis, and demanding that it does is an act of self‑inflicted pain a probabilistic belief replaces “should” with “might,” and that tiny shift removes the anger that follows a normal losing trade.
“Should” creates a false sense of control it implies that my analysis is correct and the market is wrong, which leads to holding losing positions longer than any plan allows. If the market should reverse, I will wait for the reversal. If it should respect a level, I will not place a stop beyond it. When the market does what it actually does which is whatever it wants the loss is far larger than it needed to be. Replacing “should” with “might” removes the expectation and allows me to manage risk as if any outcome is possible, because any outcome is possible.
You can begin this shift by auditing your own language. For 1 week, write down every time you think or say the word “should” about the market. At the end of the week, replace each “should” with “might” and notice how the emotional charge changes. The market might respect a level; it might not. That uncertainty is not a threat; it is the reason a probabilistic edge can exist.
The problem with “should” extends beyond the emotional reaction. It also corrupts my risk management. If I believe the market should respect a support level, I might place my stop directly at that level, leaving no room for noise. A slight break that reverses quickly will stop me out unnecessarily, and I will blame the market for being unfair. The probabilistic trader places stops where the edge’s logic is invalidated, not where the market “should” turn that distinction has saved me from countless unnecessary losses.
“Should” further makes me resistant to new information when I am certain the market should go up, I ignore signs that it might go down. I filter out contradictory data and focus only on what confirms my belief. That confirmation bias is the enemy of adaptability a probabilistic mind stays open to all outcomes and adjusts quickly when the evidence shifts.
How the Market Repeatedly Defied My Certain Expectations
I watched support levels break without hesitation, patterns fail in real time, and losses mount while I waited for a recovery that never came. The common thread was my refusal to accept randomness; I insisted the market had to follow my logic the market does not care, and my beliefs had to be rebuilt from the ground up.
The evidence was right in front of me, yet I refused to see it because my beliefs were filtering what I allowed myself to observe. A clean break of support was a fluke; a failed pattern was an exception. I was collecting data selectively, keeping the evidence that confirmed my beliefs and discarding the rest. That is not analysis; it is self‑deception. A probabilistic mind looks at the full dataset, accepts the losses as part of the distribution, and adjusts the edge accordingly it does not demand that the market conform to a story.
The rebuilding process began with a simple admission: I have no idea what the next candle will do that admission was not defeat; it was the first honest statement I had made about the market from that foundation, I could build beliefs that were based on probability rather than hope.
The repeated failure of my expectations was the curriculum I needed. Each failed trade was a lesson, if I was willing to learn. I began to record not just the trade outcome, yet the expectation I held before the trade. “I believed this support level would hold.” When I compared those expectations to the actual results, the pattern was undeniable: my expectations were wrong far more often than they were right. That data was the foundation of my probabilistic conversion.
The market is the greatest teacher of humility it does not care about my degrees, my experience, nor my confidence. It only cares about whether my actions align with probability. The sooner I accepted that the market was going to teach me whether I wanted to learn or not, the sooner I began to improve.
My Old Beliefs That Failed Me Repeatedly
Before I adopted a probability‑based mind, my head was full of specific certainties: support must hold, the pattern must deliver, the loss must come back. These were not just trading ideas they were deeply held convictions, and they failed me over and over. Recognizing them as the source of my pain was the critical first step toward change.
These old beliefs were not random; they were inherited from a world that rewards effort with results. In school, studying hard leads to good grades. In work, showing up leads to a paycheck. In trading, effort leads to process quality, yet the results are random. I had to unlearn the connection between effort and outcome before I could trade without the weight of expectation.
My old beliefs were also about how the world should work I believed that effort should be rewarded, that preparation should lead to success, and that being right should mean something. The market systematically dismantled every one of those beliefs. For a long time, I was angry about it. Now I am grateful, because the market forced me to adopt a more honest, more resilient worldview.
The Belief That a Support Level Had to Be Respected
I drew horizontal lines on the chart and treated them as laws of nature, convinced that price could not break through. When those levels gave way, I held the losing position longer, blaming the market instead of my own rigid thinking now I see support as a zone where probability shifts slightly, not as a fortress.
The fortress belief kept me in trades long after my edge said to exit. If the level had to hold, then the break must be a false signal, and I should wait for the market to correct itself. That waiting turned small losses into large ones and large ones into account‑ending ones. The probabilistic view is different: a support zone is an area where buyers have historically stepped in, and the probability of a bounce is slightly higher than random. It is not a guarantee the edge accounts for the times when the level fails, and my risk management is built to survive those failures.
The support level belief created a dangerous attachment to my analysis. I had spent time drawing the level, and I wanted that effort to be validated. The market does not validate effort; it validates probability. I had to learn to separate my ego from my analysis my analysis is a tool, not a prophecy.
The Demanding Belief That the Market Should Let Me Recover a Loss
After a losing trade, I often re‑entered or held on because I felt the market owed me a chance to get my money back. That belief turned small losses into large ones and kept me emotionally tied to a random outcome. The market has no memory of my entry, and a probabilistic mind knows that the next trade is independent.
The belief in recovery is a form of entitlement it says that my loss was unfair and that the market should compensate me. The market does not deal in fairness; it deals in probability. My loss was the result of a probabilistic outcome, not a moral wrong. The next trade does not know about the last one, and it does not care. Treating each trade as an independent event is the only way to prevent one loss from cascading into several.
The belief that the market should let me recover a loss often manifested as averaging down. I would add to a losing position because I could not accept the loss and I wanted the market to give me a chance. Averaging down is the ultimate expression of “should.” It says, “The market should reverse because I need it to.” The market does not know my needs a probabilistic mind accepts the loss, cuts the position, and waits for the next independent opportunity.
The Market Does Not Owe You Respect or Recovery
The market is not a person and it carries no memory of my past trades. When I finally accepted that price owes me nothing, the resentment that used to build up after a string of losers disappeared. That acceptance is the door through which a truly probabilistic belief system can enter.
Resentment is a heavy burden to carry into every trade it makes me defensive, impulsive, and eager to prove something. The market does not respond to resentment; it responds to orders placed according to probability. Letting go of the idea that I am owed anything respect, recovery, fairness was like putting down a weight I had been carrying without knowing it and apply a process‑based identity survives drawdowns is a self‑concept that does not depend on the market’s cooperation.
The acceptance that the market owes me nothing is not a one‑time realization; it is a daily practice. Every morning, I remind myself that the market has no memory, no obligations, and no awareness of my existence. That reminder resets my expectations to neutral. I do not enter the session hoping the market will be kind; I enter prepared for whatever it delivers.
Letting Go of the Idea That the Market Has a Memory
I used to trade as if the chart knew I had lost money and would eventually correct itself to make things right. The probabilistic truth is that each moment is a fresh draw, unaffected by the previous candle or my personal situation releasing the myth of a memory was a relief that allowed me to treat each entry with fresh eyes.
The belief in market memory is surprisingly common it shows up when a trader thinks, “I have been losing all week, so the market should give me a winner.” The market does not keep score. Each trade is a new event, drawn from the same distribution. The past does not influence the future, and my P&L is irrelevant to the next price tick. Accepting that independence is the only way to approach each trade without the emotional baggage of the last one.
The myth of market memory is a myth of fairness I used to believe that if I did the right things followed my plan, managed my risk the market would eventually reward me. It will, over a large sample, yet it might punish me for a long stretch first. The market is not fair in the short term; it is only probabilistic in the long term. Accepting that unfairness is part of the deal kept me from quitting during the difficult periods.
The One Probabilistic Belief That Replaced Everything
My entire belief system narrowed down to a single, probability‑based conviction: my edge, when executed over a sufficient sample size, has a positive expectancy. I no longer believe a given setup will work this time; I believe in the distribution. That solitary belief carries no anger, no frustration, and no need for the market to cooperate on any single trade.
This single belief is the load‑bearing wall of my trading psychology. Everything else the risk rules, the journal, the patience, the discipline rests on it. If I believe in the distribution, I do not need to win today. I do not need this trade to work. I only need to keep executing, and the math will take care of the rest. That belief is not hope; it is the logical conclusion of having validated an edge over hundreds of trades.
The single belief in positive expectancy is not a belief in my own ability to predict. It is a belief in the power of repetition. I know that my edge has a statistical advantage, and I know that if I repeat it enough times, the law of large numbers will make that advantage visible in my account. That knowledge is my foundation I do not need faith; I have data.
Why My Only Belief Now Is in the Distribution, Not the Trade
I do not wake up thinking today’s entries will win. I wake up knowing that over 100 disciplined repetitions, the edge I have validated is likely to produce a net gain. That focus on the distribution removes the pressure from any one outcome and lets me execute without hope or fear.
Hope and fear are the two emotions that drive most trading mistakes. Hope makes me hold a loser too long, waiting for a recovery. Fear makes me close a winner too early, protecting a small gain. Both are rooted in a focus on the single trade. When I zoom out to the distribution, the single trade becomes too small to hope for fear the only thing that matters is whether I am taking the trades that belong to the edge that handles the rest.
Focusing on the distribution also changes how I set goals. Instead of profit targets, I set execution targets. My goal for the month might be to take every valid setup without deviation. If I achieve that, the month is a success regardless of the P&L. The distribution will deliver the P&L over time; my job is to feed it the correct inputs.
The Shift from Believing in a Setup to Believing in a Sample
Before, I would study a chart and convince myself that this particular formation was a sure thing. Now I see each setup as merely one instance drawn from a larger pattern of results, and my belief is in the pattern, not the instance. The setup is just the trigger; the belief lives in the numbers behind it.
This shift changed how I spend my preparation time. I used to spend hours analyzing individual charts, looking for the one perfect setup. Now I spend that time reviewing my trade data, checking my adherence, and verifying that my edge’s expectancy remains positive. The individual setup is not worth obsessing over because it is just one draw. The sample is worth obsessing over because it is the truth.
The shift from setup belief to sample belief also changed how I feel about missed trades. I used to agonize over setups I missed, believing that I had lost a golden opportunity. Now I know that missed trades are irrelevant in a large sample. The edge will present another setup, and another. The sample is abundant; I only need to capture my share.
Accepting That the Market Can Do Anything at Any Time
A probabilistic belief system does not try to limit the market’s possible moves. I fully accept that price can rip through my entry, reverse without warning, stay flat all session. That acceptance means I am never shocked, and a trader who is not shocked does not make impulsive decisions.
Shock is the mother of impulsive trading when the market does something I did not expect, I feel a surge of adrenaline, and that surge demands action. I used to react to shocks by moving stops, doubling down, exiting prematurely. Now, because I expect the unexpected, there is no shock. The market can do anything, and I have a plan for every possible outcome. The plan was written in a state of calm, and it guides me through the chaos that comes when you stop needing to know the next move.
Accepting that the market can do anything also means I never argue with price. Arguing with price is the trader’s version of tilting at windmills. It accomplishes nothing and exhausts the arguer. I now accept whatever price does as the final word. My only response is to check whether my rules were followed and to prepare for the next trade.
How a Single Belief in Positive Expectancy Simplifies Every Decision
With no need to debate whether the next trade will be a winner, my decisions become binary: are my edge conditions present? If yes, I enter; if no, I wait. That simplicity is the product of having stripped away every belief that does not serve the long‑term math.
Simplicity is the ultimate sophistication in trading. When my only belief is in the expectancy, I do not need to weigh the merits of this particular setup against my mood or the news. I do not need to consider whether I feel lucky. I only need to check the conditions. That binary decision removes the mental fatigue that used to exhaust me by the end of a session.
Binary decision‑making is a form of cognitive hygiene it keeps my mind clean of the debris of indecision. There is no “maybe” in my process, no “almost.” The conditions are either present or they are not. That clarity allows me to execute without the mental fatigue that comes from weighing probabilities in real time. The probabilities were weighed when I built the edge; now I simply follow the plan.
Why I Stopped Believing in a Single Setup Working
I used to load each trade with the weight of my conviction, thinking that my belief in its success somehow improved the odds. The market, of course, never cared. I now hold zero belief about any individual outcome and instead place all my trust in the proven expectancy that emerges over a series. This section is about the moment I withdrew emotional investment from the single trade.
Emotional investment in a single trade is a debt on your mental energy. The more you believe a trade should work, the more it hurts when it does not, and the more likely you are to react poorly. I used to treat each trade as a test of my intelligence. Now I treat each trade as a spin of the wheel, and my intelligence is not on the line needs a long‑term execution mindset of a probability trader.
Withdrawing emotional investment from the single trade was not a cold, intellectual decision; it was an act of self‑preservation. The emotional toll of caring deeply about every outcome was unsustainable. I was burning out. Letting go of the single trade was the only way to stay in the game long enough for the edge to work.
The Empty Act of Convincing Myself That This Time Would Be Different
I would mentally rehearse all the reasons why a particular entry had to work, creating a story that felt airtight. Each time the trade lost, the story collapsed, and the disappointment was magnified by the energy I had invested. I learned that conviction on a single trade is a burden, not an advantage.
The story‑telling mind is the enemy of the probabilistic mind it weaves narratives that make the trade feel inevitable, and when the narrative breaks, the emotional crash is proportional to the height from which it fell. I no longer tell stories about individual trades. A trade is a set of conditions that have historically produced a positive result more often than not there is no story, only data.
The story I told myself before a trade was a form of self‑hypnosis I was trying to convince myself that the trade would work so that I could enter without fear. Yet the fear was still there, buried under the story, and it would surface the moment the trade moved against me. Now I enter without a story, acknowledging that the trade could lose, and that acknowledgment dissolves the fear before it can take hold.
Placing Belief in the Edge, Not in the Outcome
Now, before I place an entry, I ask only if the conditions match my written plan. I do not ask whether the trade will win because that question is irrelevant and unknowable. The edge’s historical performance carries my belief; the next candle does not.
This shift in questioning is the practical application of probabilistic belief the old question “Will this trade win?” is a trap because it demands a prediction. The new question “Does this match my edge?” s a checklist item. One is emotional; the other is mechanical. By asking the mechanical question, I remove myself from the role of predictor and place myself in the role of executor.
The edge’s historical performance is my evidence when I doubt whether I should take a trade, I look at the data. The data does not care about my doubts; it simply reports what has happened. A 100‑trade sample showing a positive profit factor is more convincing than any internal debate I trust the data, and I act.
The Mental Freedom of Not Needing Any One Trade to Prove Anything
When I stopped demanding that a setup validate my analysis, I freed my mind to focus on the next opportunity. A losing trade becomes just a data point, not a personal failure, and a winning trade does not inflate my ego that neutrality keeps me calm session after session.
Neutrality is the emotional state of the house. The house does not care about the last hand; it deals the next one. I now trade with that same neutrality. A loss does not require a post‑mortem; a win does not require a celebration. Both are recorded and filed the next trade is already waiting why a single trade does not define your worth as a trader.
Neutrality further protects me from the seduction of a winning streak. When I have won several trades in a row, the old ego would start to inflate, and I would begin to believe that I had special insight. The neutral mind knows that a winning streak is just variance, and it keeps my behaviour consistent. I do not increase size; I do not relax criteria. The streak will end, and I want to be positioned to survive the end.
The Vanishing of Anger and Frustration from My Trading
The day I replaced “should” with probabilistic thinking was the day anger left my relationship with the market. The market is not wrong, and I am not wrong; we are simply playing out probability. Frustration cannot survive in a mind that truly understands that a losing streak is just a normal dip in the distribution this section describes the emotional weight that lifted.
Anger used to be my constant trading companion I was angry at the market for not respecting my levels, angry at myself for losing money, angry at the world for not rewarding my effort. That anger clouded every decision and drained my energy. Probabilistic thinking dissolved the anger by removing its source: the belief that the market should behave differently than it did.
Anger was the emotion I felt most often in my early trading years. I was angry at the market, angry at myself, angry at the gurus who had sold me false promises. That anger was toxic, and it poisoned my decision‑making. The shift to probabilistic beliefs was the detox I needed. It did not happen overnight; rather, each probabilistic thought weakened the anger how the casino mindset teaches indifference to single outcomes.
How Probabilistic Beliefs Erased the Blame I Placed on the Market
I used to curse the market after a loss, as if price action had personally wronged me. Now I see that every outcome, favourable or not, is contained within the known variance of my edge. There is no one to blame, and that absence of blame keeps my mind clear for the next decision.
Blame is a search for a villain, and the market is not a villain. It is a system. When I understood that my edge’s historical performance includes losing streaks just as it includes winning streaks, the need to blame vanished. The loss was not a wrong; it was a statistical event. The event requires no emotional response; it requires a data entry in my journal.
Blaming the market is a way of externalizing responsibility if the market is at fault, I do not have to examine my own process. Probabilistic beliefs forced me to take full responsibility for my results. The market is not to blame for my losses; my edge’s variance is that responsibility was initially uncomfortable, yet it empowered me to improve.
The Realization That a Losing Streak Is Not a Moral Failure
Under a probabilistic lens, a string of losses is not evidence that I have done something bad; it is evidence that my edge’s distribution is tilting as expected. I do not punish myself for normal variance, and I no longer feel the shame that used to follow a series of red entries.
Shame is the emotion of a deterministic mind. It says, “I lost, therefore I am a loser.” The probabilistic mind says, “I lost, and that was one of the expected outcomes in the distribution.” The difference is night and day. Shame leads to quitting; acceptance leads to persistence. I persist because I understand the math.
A losing streak is not a moral failure; it is a statistical event that single sentence, repeated daily, rewired my response to losses. I no longer felt the need to confess my losses as if they were sins. I simply recorded them and moved on. The shame dissolved, and with it, the fear of loss that had kept me from taking valid trades.
Trading Without the Emotional Highs and Lows
When I stopped believing that the market should behave in a particular way, the emotional roller coaster flattened out. A win does not bring euphoria, and a loss does not bring despair; both are just points on a curve that I know tends upward over time. That emotional stability is the hidden payoff of probabilistic beliefs.
The roller coaster is exhausting I used to finish a winning day wired and a losing day drained. Now I finish every day with the same calm energy. The market’s outcomes do not dictate my mood because my mood is anchored to my process, not to the results the process is always available; the results are random.
The flattened emotional state is sometimes mistaken for boredom, yet it is actually peace. I am not bored by trading; I am at peace with it. The absence of drama is the sign that my beliefs are aligned with reality. A peaceful trader is a profitable trader, not because peace creates profits, yet because peace allows the edge to operate without interference.
The Mindset That Replaces Anger with Calm Observation
Now, when a trade moves against me, I observe it with the same detachment as I would a coin toss. I record the result, review my rule adherence, and move on. That calmness is not suppression; it is the natural state of a trader whose beliefs are built on odds, not demands.
Calm observation is a skill that grows with practice at first, I had to consciously remind myself that the loss was just variance. Over time, the reminder became unnecessary. My mind now defaults to calm because it has been trained on hundreds of trades where the edge recovered from losses. The calm is earned, and it is self‑reinforcing.
The observation is not detachment; it is focused attention without emotional attachment. I am fully engaged with the market, yet I am not emotionally entangled. That state is the ideal performance state for any probabilistic task. It took years to build, yet it is now my default mindset.
Probabilistic Beliefs as the Foundation of Sustainable Profitability
Changing your beliefs to probabilistic ones is the first genuine step toward results that last beyond a few lucky runs. When my mind operates on the assumption that only the long‑term distribution matters, I can adhere to a plan through drawdowns and keep taking the next trade without hesitation. Sustainable profitability is not born from a perfect entry method; it is born from a belief system that survives every market condition.
The entry method is secondary; the belief system is primary a trader with a mediocre edge and solid probabilistic beliefs will outperform a trader with a brilliant edge and deterministic beliefs, because the first trader will keep executing through the drawdowns while the second will quit or sabotage the edge. Beliefs drive behaviour, and behaviour drives results.
Sustainable profitability is not found in an indicator or a strategy it is found in a belief system that can endure the psychological rigors of real‑world trading. Probabilistic beliefs are that system. They are the foundation on which all other trading skills are built.
How Probabilistic Thinking Protects the Trading Plan Through Drawdowns
A drawdown under a probabilistic belief is not a crisis; it is an expected phase. Because I believe in the edge’s long‑term expectancy, I continue to execute the plan without altering the rules stopping out of fear. That persistence is what allows the edge to eventually recover.
The drawdown is the test of belief when the account is down and every instinct says to stop, the probabilistic belief is what keeps me in the game. I look at my historical data, see that the edge has recovered from similar drawdowns before, and I trust that it will again. That trust is not blind; it is based on evidence. The evidence is my foundation.
A drawdown is the ultimate test of probabilistic belief when the account is shrinking and the losses are mounting, the deterministic mind panics and abandons the edge. The probabilistic mind checks the data, confirms that the drawdown is within historical norms, and continues executing. That continuation is what allows the edge to recover. Every recovery I have experienced was preceded by a drawdown during which I did not quit.
The Link Between Belief in the Distribution and Consistent Execution
When I truly believe that the edge will work over a large sample, I do not hesitate on the next setup, even if the previous 5 trades lost. That consistent execution, which probabilistic belief enables, is the very mechanism through which the edge compounds. Without that belief, I would skip trades and break the series.
Skipping trades is the silent killer of expectancy every trade I skip because of fear or doubt is a trade that could have contributed to the edge’s positive result. Probabilistic belief ensures that I take every trade the edge presents, because I know that the edge needs the full sample to express itself. Missing trades biases the sample and degrades the edge.
The link between belief and execution is direct if I believe the edge will work, I take every trade. If I doubt the edge, I skip trades. Skipped trades are the hidden enemy of expectancy. They are not recorded in the P&L, yet they are recorded in the long‑term equity curve as missing profits. Probabilistic belief eliminates skipped trades by removing doubt.
Why the Shift Away from “Should” Unlocks Long‑Term Discipline
Demanding that the market “should” do something always leads to emotional decisions that undermine discipline. Letting go of that demand frees me to follow my rules without internal resistance. Long‑term discipline is simply the practice of acting on probabilistic beliefs, day after day.
Internal resistance is the voice that says, “This trade might not work; maybe I should skip it.” That voice is the residue of “should.” When I let go of “should,” the voice calms. There is no internal debate because there is no demand for the market to behave a certain way. The rules are the rules, and I follow them.
Letting go of “should” is a daily practice. Every time I catch myself thinking that the market should do something, I correct myself. “The market might do that, and it might not. My edge accounts for both.” That correction is a small act of mental discipline, yet cumulatively, it builds the probabilistic mindset.
The First Step to a Trading Career That Outlasts Any Single Market Phase
The market will change, and edges will move in and out of favour, yet a probabilistic mind adapts without breaking. By anchoring my beliefs solely in the idea that a validated edge yields positive expectancy over time, I have built a foundation that no single market phase can shake. That foundation is the real path to sustainable profitability.
Market phases are temporary; a probabilistic belief system is permanent. When my edge underperforms, I do not panic because I know that underperformance is within the edge’s historical range. When the market shifts, I adapt my edge based on new data, not based on fear. The belief in the distribution remains constant, even as the specifics of the edge evolve killing the ego to let the statistical edge work.
The first step is to write down your probabilistic belief. “I believe that my edge, when executed consistently over a minimum of 100 trades, has a positive expectancy.” Read it before every session. Let it be the filter through which you interpret every outcome. Over time, that belief will become the foundation of your trading psychology, and the anger, frustration, and “should” will fall away.
The first step to a probabilistic trading career is to write down your edge’s expectancy over a large sample then, every time you experience a loss, read that expectancy statement. Let it remind you that the loss is part of the distribution, not a failure of your character. Over time, that statement will become the foundation of your trading psychology.
