If your margin level drops below 100%, you may not open new spot positions on margin until your margin level is back over 100%. If your margin level drops to 80% or lower, your positions may be forcibly closed or “liquidated” (see "margin call level" and "margin liquidation level"). It is your responsibility as a trader to proactively monitor your margin level.

Margin level = (equity ÷ used margin) × 100
