Order Cost Calculation

Venkate coin-margined order cost is the total margin required to open a position. It includes the initial margin and the taker fees for both opening and closing positions. The actual trading fee/rebate depends on the order type and how it is executed (as a maker or taker).

In cross margin mode, the margin includes the initial position margin and the available balance.

Order Cost = Initial Margin + Opening Fee + Closing Fee Opening Fee = (Contract Quantity / Order Price) x Taker Fee Rate Closing Fee = (Contract Quantity / Bankruptcy Price from Order Price) x Taker Fee Rate Bankruptcy Price (Long) = (Average Entry Price x Leverage) / (Leverage + 1)

Example:

A trader uses 25x leverage (initial margin 4%) and submits a limit order of 10,000 BTCUSD contracts at 6,400 USD.

• Initial Margin: 10,000 / 6,400 x 4% = 0.0625 BTC
• Opening Fee: (10,000 / 6,400) x 0.06% = 0.0009375 BTC
• Bankruptcy Price: 6,400 x 25 / (25 + 1) = 160,000 / 26 ≈ 6,154 USD
• Closing Fee: (10,000 / 6,154 USD) x 0.06% = 0.00097498 BTC
• Total Order Cost: 0.0625 BTC (Initial Margin) + 0.0009375 BTC (Opening Fee) + 0.00097498 BTC (Closing Fee) = 0.06441248 BTC

*Note: The order cost for a limit order is calculated using the order price, while for a market order, it is calculated using the market price obtained from current market depth.
