When the margin level drops below 100%, traders lose ability to increase exposure. which is known as a Margin Call Level. You can still reduce your exposure by closing some or all your positions. If the margin level keeps declining to or below your stop out level, an automatic process in MT5 will be initiated causing the positions to be liquidated. This entails the closure of positions, prioritizing those with the greatest loss to profit ratio. The process continues until the remaining exposure attains a level adequate to accommodate any active positions.
