How to create order with BTC instead of Contracts in COIN-M ?

Hi ,
I would l like to create order with my available BTC
let say if i have 3 BTC in my account, How can i create limit order with 3 BTC instead of contracts ( Delivery Type -COIN-M ) ?

Note: Binance website providing contracts and BTC trade, where as in API, have only trade order with contracts

Hello, for Coin-M Futures API, there’s a parameter named “workingType” where you can set “MARK_PRICE” or “CONTRACT_PRICE”, however at the moment “MARK_PRICE” is only available to be used for orders with a stop price (STOP/STOP_MARKET or TAKE_PROFIT/TAKE_PROFIT_MARKET orders)
