Your strategy never gets greedy

This is the second in a theme that started with your strategy never gets bored: the systematic edge is valuable precisely because it lacks the emotions that wreck discretionary traders. Greed is near the top of that list. It almost always appears after success — a green day, a hot streak — exactly when your guard is down.

Why greed costs more than it captures

The greedy actions all share a structure: they increase risk to chase incremental reward the plan didn't promise. Sizing up after wins is the classic — it's how a winning streak sets up an oversized loss that erases days of gains in one session. On a trailing-drawdown prop account this is fatal, because a single greedy loss permanently tightens your floor.

The system's immunity is the feature

A strategy doesn't care that it just won. It sizes the next trade exactly as the rules dictate, takes the defined target whether or not it “feels” like more is available, and sits flat when there's no setup rather than manufacturing one. That indifference isn't a limitation — it's the entire reason a tested edge survives: it never trades the emotion of the last result, only the math of the next setup. This is the same discipline as thinking in probabilities.

How to borrow the system's discipline

Pre-commit your size and never raise it intra-session because you're winning. Take your planned target. Define in advance the only conditions under which you add to a position — and if none are met, you don't add. The urge to extract “more” is the signal that greed, not edge, is driving — and that's precisely when sticking to the plan matters most.
