Position size calculator for Aster traders

What this estimate includes

This is a planned stop-loss budget, not an exact liquidation calculator or guaranteed loss limit. Stops may slip or fail. Assumes a linear contract and unchanged fee rate; excludes funding and collateral haircuts. If estimated margin exceeds equity, the scenario is not funded by the entered equity.

The formula

Risk budget = equity × risk percentage ÷ 100. Quantity = budget ÷ (absolute entry-to-stop distance + estimated entry and stop-exit fees per unit). Notional = quantity × entry price. Initial margin estimate = notional ÷ leverage. Leverage does not change the planned price-loss budget.
