Holding some assets earns you interests and the other charges you interest. When you participate in currencies trading, this interest will be calculated by the sum of both sides. The method for calculating this interest is: opening price × contract size × days held / 360 × interest rate. During the weekend, there is a compulsory locking of open positions. This means that the system will automatically lock open market positions, freezing the buy/sell price at the time of the market close. The weekend starts on Friday GMT+0 21:00 and markets open back up Sunday GMT+0 20:00. In the case of a holiday, open positions will also be locked. For cryptos, the holding interests will vary and the market opening time is 24/7. Maintenance margin refers to the requirement to have a certain amount of margin in the customer's trading account to withstand market volatility during the time while the position is open. If the client account margin ratio falls to 30% or less, the system will be forced to stop the transaction at that time.
