**USDⓈ-M Perpetual Futures**

Initial Margin = Quantity * Entry Price * Initial Margin Rate(IMR)

Initial Margin Rate (IMR) = 1 / leverage Multiplier

Calculation for PnL:

Long = (Exit Price - Entry Price) * Number of Contracts

Short = (Entry Price - Exit Price) * Number of Contracts

ROE% = PnL / Initial Margin = Order Direction * (1 - Entry Price / Exit Price) / Initial Margin Rate
