Most traders don’t lose because their analysis was wrong. They lose because they sized one trade too big — or because four reasonable trades were open at once and all went wrong together.
Free calculators size one trade, then forget it. This doesn’t.
SIZE A TRADE
Account, risk, entry, stop. Get the exact position in units or forex lots — with reward-to-risk, breakeven after fees, and margin at any leverage.
