Psychology: problem → solution (the practical guide)
Most psychology modules DESCRIBE the problem; this one gives you the SOLUTION. Each card names a real problem —in your own voice— and its concrete fix, drawn from the best (Brett Steenbarger, Mark Douglas) and from behavioural science. The base tool is the "if-then" plan: it turns self-control (which runs out) into an automatism. Don't read this once: turn it into rules in your plan.

The base: "if-then" plans
The most science-backed technique for changing behaviour under pressure. The problem: "in the heat" you don't reason, you react, and willpower runs out. The solution: pre-define a plan of the form "IF [trigger] happens, THEN I do [pre-decided action]" — for example, "IF I lose two trades in a row, THEN I close the platform for 30 minutes". By pre-deciding the response, you execute it almost automatically, without spending self-control. Every solution below is an if-then plan.
“I just lost and I want it back NOW”
The problem: after a loss, anger pushes you to open a bigger trade to "get even" with the market; Steenbarger calls it a dangerous, irrational way to use your capital. The solution: a hard stop rule (a daily loss limit) and a circuit breaker — "IF I lose X, THEN I stop for the day". And before EVERY trade, define what would tell you you're wrong and how much you're willing to lose. Revenge vanishes when the decision is already made by rules.
“I move or remove the stop when it goes against me”
The problem: when price nears your stop, hope makes you move it "a little more" so you don't accept the loss… and the small loss turns huge. The solution: accept the risk BEFORE entering (Mark Douglas: if you aren't willing to lose that amount, it isn't your trade) and use a mechanical stop (a broker order you don't touch). And note in your journal every time you move it: seeing the pattern in writing is what breaks the habit (Steenbarger).
“I enter late for fear of missing the move”
The problem: price takes off without you, you feel it "getting away" and you jump in right at the top, with no edge and the stop miles away. The solution: a simple rule —I only enter on MY setup, not on the move—. Set alerts and a watchlist instead of chasing. Internalise that the market opens thousands of opportunities: there's always another train, and chasing the one that left is like overpaying to arrive late.
“I'm afraid to pull the trigger”
The problem: you have the setup but don't enter; fear of losing paralyses you and you watch good trades go by. The solution: shrink the size until the possible loss is emotionally irrelevant —if risking hurts, you're risking too much—. Add mental rehearsal (visualise executing the plan, win or lose) and automate the entry with orders to take your hand out of the equation. And measure success by following the process, not by that trade's outcome.
“I trade too much, sometimes just out of boredom”
The problem: you trade with no clear signal, out of boredom, adrenaline or to "be in the market"; every extra trade adds commissions and mistakes. The solution: set a daily trade quota and a mandatory checklist before each one —if it doesn't tick every box, there's no trade—. Identify your trigger (boredom, euphoria after winning) and apply an if-then: "IF there's no A+ setup, THEN I touch nothing".
“I cut winners and let losers run”
The problem: the disposition effect —you close winners quickly for fear they'll reverse, but hold losers hoping they'll come back—; the result is many small gains and a few huge losses, the exact opposite of what works. The solution: set your exits BEFORE entering (a target in risk multiples, or a trailing stop) and respect them. And separate the decision from the outcome: a good decision can lose and a bad one can win; judge the process.
“After a streak I lose control (tilt)”
The problem: a streak —losing OR winning— takes you out of your normal state; overconfidence after winning is as dangerous as fear after losing (Steenbarger), and both lead you to break your rules. The solution: a quick emotional check before trading (am I calm or heated?), a pause when you notice you're "revving up", and shrinking size until you regain control. The market will still be there tomorrow.
“I bet everything on THIS trade working out”
The problem: you live each trade as a verdict on you; a loss feels like a personal failure, and that sets off every other mistake. The solution: Mark Douglas's probabilistic mindset —"anything can happen"—. A trade is just one event from a distribution; your edge isn't measured in one but in series of 20, 50, 100. When you think in the series, an individual loss stops hurting and you execute calmly.
