FAQ
How is required margin calculated?
Margin = (lots × contract size × entry price) / leverage. The result is in the quote currency; multiply by the quote→account FX rate to get it in your account currency.
What leverage should I use?
Use the leverage your broker actually grants you for that instrument. EU/UK retail forex is capped at 30:1, gold at 20:1, indices at 20:1, crypto at 2:1. Offshore brokers may offer more.
Free margin vs required margin?
Required margin is the amount locked when you open the trade. Free margin is your equity minus required margin, what's left to absorb losses or open more trades before a margin call.
