Risk Management

Risk management is the stack of constraints around a strategy: risk per trade, risk per day, risk per correlated theme, maximum open positions, and the conditions under which you stop trading. It is not the stop loss alone. A trader with a perfect stop and no daily cap can lose the daily cap ten times by taking ten setups. A trader with a small size and no stop can lose more than the small size in one gap. The layers cover different failures. The aim is survival of the process. A system with a real edge and poor risk limits goes broke. A system with no edge and perfect limits bleeds slowly and at least remains available for the next, better idea.

Write three numbers and one rule. The fraction per trade. The loss at which the day ends. The maximum number of positions that share one bet, one sector, one event, one index direction. The rule is what you do when a limit is hit: flatten, or stop entering, and do not negotiate. Review the day against the numbers, not against the story of the market. If you hit the daily stop, the afternoon setup is not a reason to continue. It is the setup that the rule exists to refuse. Reset the next session. Revenge trading after the daily stop is how a bad morning becomes a bad month.

Put risk management ahead of the setup in the decision order. First, are you allowed to take a new trade today. Second, does this trade share its risk with something you already hold. Third, does the setup meet the plan. Entries are the interesting part and the least important part of staying in the game. When a strategy is new, cut the fraction until the behaviour is stable. You can add size when the journal shows the exits match the plan. You cannot add size to repair a hole.

Equating risk management with a tight stop. Also moving the daily stop because the next trade "is the one." And hedging in a way you do not understand, which can add risk, a short call against a long, a correlated ETF that does not actually offset the book. If you cannot state the worst case of the combined position, you do not have a hedge. You have two trades.

Limits do not cover a venue failure, a margin change, or a price that does not trade. They reduce damage. They do not create an edge. A trader who uses risk management as a reason to take more low-quality setups, because "the risk is small," has missed the point. Small risk on a bad location is still a bad trade, and small risks add up. The daily cap is what catches that. Without it, a tidy per-trade risk is a leak.
