How it works

risk $ = account × risk %

size = risk $ ÷ |entry − stop|

Worked example

Risking 1% of $10,000 with entry $65,000 and stop $63,000: $100 risk over a $2,000 stop distance sizes you at 0.05 BTC, a $3,250 position.

FAQ

What is my position size if I risk 1%?

Divide 1% of your account by the distance between entry and stop. That quotient, in coins, is your size; this tool does it live.

Why does a tighter stop mean a bigger position?

Same dollars at risk spread over fewer dollars of price distance. The risk stays constant; only exposure changes.

Does leverage change this?

No. Leverage changes margin required, not correct size. Size from risk first, then check margin fits.
