Risk Management in Trading

The single most important number

Decide, before you trade, what percentage of your account you are willing to lose on a single position. For most newcomers, this number should be small — often less than 1%. Everything downstream of this decision is mechanical.

Position sizing, mechanically

Position size = (Account × Risk %) ÷ (Distance from entry to stop). That formula keeps risk constant regardless of instrument volatility. A wider stop produces a smaller position. A tighter stop produces a larger one. The risk is the same dollar amount either way.

Where to place a stop

A stop should sit at a level where, if reached, the trade idea is invalidated. Not arbitrary distances. Not "the most I'm comfortable losing." Use structure — beyond a swing low, beyond a recent range — and then size the position to match.

Expectancy

A strategy's edge is its expectancy: (win rate × average win) − (loss rate × average loss). A 40% win rate with a 2.5:1 win/loss ratio is profitable. A 70% win rate with a 1:3 ratio is not. Don't confuse being right often with being profitable.

Drawdowns are normal

Even a profitable strategy will produce stretches of consecutive losses. Plan for them. If a 10-loss streak would force you to stop trading emotionally, your size is too large.
