Question 1

What is a margin call?

Accepted Answer

It is the point where your equity falls to the maintenance-margin level and the exchange requires more collateral. Ignore it and the position gets liquidated. On most crypto perps the margin call and liquidation are nearly the same price.

Question 2

How do I avoid margin calls?

Accepted Answer

Use less leverage, keep spare margin in the account, and set a stop-loss well above the call price. The higher the leverage, the smaller the move that triggers a call — which is why over-leveraged positions die on ordinary volatility.
