A percentage that indicates the health of your account in margin trading, calculated as (Equity / Used Margin) × 100%. For example, if you have $5,000 equity and $1,000 used margin, your margin level is 500%. Brokers use margin level to trigger margin calls and stop outs. Commonly: at Margin Call Level (say 100% margin level), you’re alerted or restricted from opening new trades; at Stop Out Level (e.g. 50% or 20%), the broker will begin automatically closing positions. In practice, you want your margin level to stay comfortably high. If your EA is in heavy drawdown, margin level falls – e.g. if equity drops to $500 while $1,000 margin is used, margin level is 50% and a stop out would occur. Thus, margin level is a crucial metric for robots that use high leverage or hold many positions. It’s wise to program EAs to halt trading or close loss-making trades before margin level gets dangerously low.
