Track my real exposureHow margin and leverage work
Margin is the deposit held while a leveraged position is open. Leverage is the ratio that determines how small that deposit can be relative to the exposure it controls. More leverage frees margin, but it also makes it easier to carry more exposure than the account can support.
The formula
Required margin = position value / leverage. One standard lot of EURUSD at 1.10 controls $110,000, so at 1:100 leverage it requires about $1,100 of margin.
Effective leverage is the number to watch
The account may allow 1:100, but a $110,000 position on $10,000 of equity is 11x effective leverage. That ratio describes the exposure you are actually carrying, regardless of the maximum the account permits.
