RISK & PLANNING TOOL
Size a trade from your account risk, entry, and stop.
Update any value to recalculate.
Calculated from the values above.
Position size is rounded down to whole units. Confirm liquidity and buying-power requirements before placing a trade.
This tool turns a defined account-risk budget into a maximum whole-unit position size.
Set the account value and a risk budget you can actually tolerate, then enter a planned entry and stop. Use the rounded-down result as a ceiling, and reduce it further if liquidity or gap risk makes the stop uncertain.
Risk budget equals account size × risk percent; position size rounds down risk budget ÷ absolute entry-to-stop distance.
The result assumes the stop can be executed near the entered level. Gaps, slippage, illiquidity, and correlated positions can make realized risk exceed the planned amount.
A $10,000 account risking 1% with a $5 stop distance has a $100 budget and can take 20 units.
Use the rounded quantity as a ceiling rather than a target. If the entry-to-stop distance widens, the same account-risk budget supports fewer units.
Sizing a position from a percentage alone ignores stop distance. A small risk percentage can still create a large dollar loss if the planned exit is far away.
Stops can slip and position sizing does not guarantee a realized loss limit.
