Size the position before you take it

The risk calculator turns 'how many contracts?' into arithmetic: set your account risk percentage, enter your stop, and get the exact size — every trade, same risk.

Fixed-percentage account risk sizing
Exact position size from entry and stop
R-multiple and reward:risk shown up front
Supports futures ticks, forex pips, and shares
Fractional sizing for crypto and forex
Saves your default risk settings

Position sizing is the edge most traders skip

Two traders can take identical entries and end the year in opposite halves of the P&L distribution purely on sizing. Risking a fixed 1% per trade means a normal losing streak of five trades costs about 5% of the account — recoverable. Improvised sizing means one emotional oversize can erase a month.

The maths of drawdown is brutal and worth knowing: lose 20% and you need +25% to get back; lose 50% and you need +100%. Fixed-fractional sizing exists to keep you off that curve.

From stop distance to exact size, instantly

The calculation is simple but tedious under pressure: account size × risk % ÷ stop distance, converted through tick or pip value for your instrument. The calculator does it instantly and shows the R-multiple of your target at the same time — so a sub-1R trade is exposed before you take it, not after.

Your risk percentage and account details are saved, so pre-trade sizing becomes a two-field habit: entry, stop, done.
