About limit order and market order (limit_price, cost, quantity)
ProBit Exchange supports limit order and market order.
You may use limit order with type: limit, limit_price, and quantity parameters, to put new order with specific price and quantity into orderbook. (cost cannot be used with limit order.)
Or you may use market order with type: market, cost, and quantity parameters, to set market order cost. (limit_price cannot be used with market order.)
Market buy
When purchasing, you can use cost to specify the total limit of market price * quantity. In this case, quantity cannot be used.
When selling, you can use cost to specify the total limit of market price * quantity and quantity to specify the maximum sales quantity. (cost must be less than the user's balance.)

📘
Supported type, time_in_force combination
If you are ordering "Limit" order,
all time_in_force will be supported.
If you are ordering "Market",
IOC or FOK will be supported.
