Risk per trade

Esta página legal está disponible únicamente en inglés.

Risk per trade is defined by the stop distance and the position size together: entry at 2400, stop at 2390, and a size where each point is worth $10 means $100 at risk. Expressed as a percentage of equity, it becomes comparable across trades and accounts.

Small per-trade risk keeps sequences of losses — which every strategy has — from compounding into unrecoverable drawdowns. At 1% risk, ten straight losses cost roughly 9.6% of the account. At 10% risk, the same streak costs 65%.
