Liquidation Price (Margin type: Isolated Margin, traders are allowed to add in the extra margin to position)

Liquidation is triggered when the Mark Price hits the Liquidation Price.

Maintenance Margin Rate (MMR) is based on Tiered Margin.

Example:

Trader place a long entry of 1 BTC at 80,000USDT with 40x leverage. Assuming no extra margin added.
 78000/0.996 = 78313.25301

Liquidation price 78313

Example:

Trader place a short entry of 1 BTC at 80,000USDT with 40x leverage. Assuming no extra margin added.
88000/1.004=87649.40239

IM = Mark  price    x    Quantity    /    Leverage

MM = Mark price    x    Quantity    x    MM Rate% for the particular pair

IM% =  IM    /    Margin balance

  Margin balance = Wallet balance + Unrealized PL based on Mark price (in USDT) 

MMR  =  MM    /    Margin balance 

Unrealized P&L formula   

            Long:        Unrealized P&L = Contract Qty x (Mark price - Entry Price)                    
            Short:         Unrealized P&L = Contract Qty x (Entry Price - Mark Price)
