How it works

Position sizing ties loss size to a fixed fraction of your equity. If price hits your stop, you lose only the risk amount you chose — not a random chunk of capital.

Formula

Position size (units) = (Account balance × Risk %) ÷ |Entry − Stop|

Examples

Spot BTC long

Balance $10,000, risk 1%, entry $65,000, stop $63,000 → risk $100, stop distance $2,000 → 0.05 BTC ($3,250 notional).

Tighter stop

Same balance and risk with entry $65,000 and stop $64,500 → stop distance $500 → 0.2 BTC ($13,000 notional). Tighter stops increase size for the same dollar risk.

FAQs

How much should I risk per crypto trade?

Many discretionary traders keep risk between 0.25% and 2% of equity per idea. Lower risk helps when volatility or leverage is high.

Does this work for futures?

Yes for sizing the notional exposure from stop distance. Separately check margin, leverage, and liquidation with the liquidation and leverage calculators.

What if entry equals stop?

Stop distance must be greater than zero. Choose a stop that reflects invalidation of your thesis, not a random round number.
