How it works
- · Risk amount = Balance × Risk %.
- · Lots = Risk amount ÷ (Stop in pips × pip value per lot).
- · Units = Lots × 100,000 (1 standard lot = 100k units).
Pip value is ~$10 per standard lot for USD-quoted pairs (e.g. EUR/USD); it differs for JPY pairs and cross-currencies, so set your pair's actual pip value for an exact figure.
