Futures position size calculator
Size the trade from risk first: pick a contract, set how many dollars you are willing to lose at the stop, and get the maximum whole-contract size that fits.
Risk per contract
$20.00
Max contracts
10
Actual risk at that size
$200.00
How the math works
Risk per contract = stop ticks × tick value. Max contracts = floor(risk budget ÷ risk per contract). We round down so you never exceed the budget on a full tick stop-out (fees and slippage are not included).
On tight prop firm daily loss limits, micros often fit the budget when a mini does not. After you pick a size, enforce the same dollar risk per account in MimikTrader so a copied signal cannot oversize a smaller evaluation.
Educational calculator only. Not financial advice. Contract tick values are CME standards and can change; verify with your broker. Prop firm rules vary — check your current firm agreement.
Copy the trade. Enforce the rule.
MimikTrader copies futures trades across prop accounts and enforces per-account risk limits on live ticks.
