How the estimate works

Risk budget = balance × risk percentage
Risk per unit = |entry − stop| × value per point
Position size = risk budget ÷ risk per unit
Break-even rate* = risk ÷ (risk + potential reward)

Important assumptions

This is an estimate, not financial advice or a trade recommendation.
It assumes linear price movement, a constant contract multiplier,
and no fees, slippage, or currency conversion. Actual losses can
exceed the estimate, especially if a stop does not execute at its
set price.
