How many contracts should you trade? Enter your numbers and find out.
One account, one answer. Drawdown, risk, instrument, stop — you'll know your contract count before the pre-market opens.
This calculates how many futures contracts you can trade based on your available drawdown and risk tolerance. It floors the contract count (no partial contracts), multiplies by the instrument's dollar-per-point value, and shows you how many consecutive losers you can survive at this size. If the blow counter is under 10, you're probably oversized.
The full calculator handles multiple prop firm accounts, different drawdown types, and distributes contracts proportionally. Plus Monte Carlo sims and payout estimates.
Size all my accountsYour win rate and average win/loss tell you whether your strategy actually makes money. If expectancy is negative, no amount of sizing will save you.
