Question 1

What is maintenance margin?

Accepted Answer

The minimum equity an exchange requires to keep a leveraged position open. If your equity (initial margin minus losses) falls to this level, you get liquidated. It's usually a small percentage of the position size.

Question 2

How is it different from initial margin?

Accepted Answer

Initial margin is what you post to open (size ÷ leverage). Maintenance margin is the lower floor you must stay above. The gap between them is your loss buffer before liquidation.
