[Perpetual Futures] Usdt-Margined Cross Position Futures Liquidation Explanation

The liquidation price equals to:

[Total cross position assets + other unrealized profits&losses - long position holding costs + short position holding costs - market value of other positions * (present position margin rate + present position liquidation rate)]/[(present position margin rate + present position liquidation rate) * current trading pair multiplier * (long position order counts + short position order counts) + present trading pair multipier * (short position order counts - long position order counts)

Notes:

1. Position holding cost is the basic cost of holding the position, which equals to:

          Open position average price * position counts * trading pair multipier

1. Position market value = trading pair mark price * position counts * trading pair multipier
2. Unrealized profits&losses = (position market value - position holding cost) * position direction, (1 for long position, -1 for short position).
3. present position liquidation rate = taker fee
4. Trading Pair Multipier: token amount of each order, eg: 1 BTCUSDT future order equals to 0.001 BTC.
