What is Margin?

Margin is the account equity set aside to open and maintain leveraged positions. Free margin is what remains for new trades or to absorb floating losses.

A Signal that looks small in pips can still consume margin if lot size is large. Position sizing and margin are related but not identical: sizing targets dollar risk at the stop; margin is the broker's collateral rule.

If margin is exhausted, brokers can stop you out regardless of the Signal's published stop loss.
