Isolated margin is the amount of margin that is allocated to an individual position. Cross margin is margin that is shared between open positions with the same denominated cryptocurrency. With isolated margin, traders can manage the risk on individual positions by restricting the amount of margin allocated to each one. With cross margin, a position can draw more margin from the total account balance of the corresponding cryptocurrency to avoid liquidation.
Daily interest rates
Traders must pay interest for the benefit of the margin they receive from brokers. This interest rate is typically calculated hourly and rolled up into a daily average rate. Traders can find out how much interest they are liable to pay by consulting the fees section of the crypto exchange or broker they are using.
