Margin Call Level
Risk ManagementThe margin percentage at which a broker warns you. It is a warning, not the liquidation — the stop-out level sits below it.
The margin call level is the margin percentage at which a broker warns you that your account can no longer support its open positions — commonly 100%, meaning your equity has fallen to the margin the positions require.
It is a warning, not the closure. The stop-out level below it is where positions start being liquidated, usually at 50% or 20%. Two things surprise people: the warning may arrive by email you will not read in time, and in fast markets the account can travel from margin call to stop-out in seconds, so treating the call as a moment to "add funds later" is how accounts end.
