A Margin Call is triggered before a Stop Out. It occurs when there are insufficient funds in your trading account to open and/or sustain trades. This is also when your floating losses are greater than the minimum margin required/available.
A Stop Out occurs after a Margin Call. It is when all the trading positions reach the stop out level, and the floating trade with the highest volume would be closed forcefully at the current market prices to prevent any future losses.
