When you use M1 Borrow, your current borrowing status will be displayed to show you how far away your account is from a maintenance call.
If the value of your portfolio drops, your account can approach a required maintenance call.
M1 Borrow will display your current status, including color-coded ranges "Great", "Good", "Okay", "Caution", Danger", and finally "Maintenance Call"
If your account value drops so that your equity value is below our maintenance threshold, M1 will issue a maintenance call. The maintenance threshold is normally 30% of your account value but M1 may impose additional restrictions based on risk of securities held or portfolio concentration.
When a maintenance call is issued your account will be frozen, you will have to either deposit additional cash or sell a portion of your portfolio to make up for the maintenance call. Please read all additional maintenance disclosures here: Margin Disclosures
