The calculation of IM and MM for USDT margined perpetual is as follows:
Initial Margin = Notional Position Value / Leverage Level
Maintenance Margin = Notional Position Value * Maintenance Margin Rate - Maintenance Amount
Please be aware that in the event of extreme price movements or deviation from the price index, BIT will undertake additional protective measures, including but not limited to:
1. Adjust maximum leverage value - Refer here
2. Adjust position bracket in each tier
