Margin
In short
Margin is the collateral you post for a leveraged position. It determines how much loss the position survives before liquidation.
"Isolated" margin limits risk to the single position; "cross" margin puts the whole account on the hook. For controlled risk, isolated is the clear recommendation.
What is a margin call?
The demand to top up collateral before liquidation — with crypto perpetuals often skipped entirely: you simply get liquidated.
