In the futures market, margin refers to the initial deposit of "good faith" made into an account in order to enter into a futures contract. This margin is referred to as good faith because it is this money that is used to debit any day-to-day losses.
OKEX provides two margin modes – the cross-margin mode and compartmentalized margin mode. In terms of the former, users’ margin level floats with the market prices. In the later, the margin level stays unchanged irrespective of the market price fluctuation.
