The Market order type is an order to buy or sell at the market bid or offer price. The supported products via our Trader Workstation API are: BOND,  EFP, CASH, FUND, FUT, FOP, OPT, STK, WAR . Below is an example on how to code it in Python:

    @staticmethod

    def MarketOrder(action:str, quantity:float):
        #! [market]
        order = Order()
        order.action = action
        order.orderType = “MKT”
        order.totalQuantity = quantity
        #! [market]
        return order

Limit order is an order to buy or sell at a specified price or better. The supported products via our Trader Workstation API are: BOND, CASH, FUT, FOP, OPT, STK, WAR. Below is an example on how to code it in Python:

    @staticmethod

    def LimitOrder(action:str, quantity:float, limitPrice:float):
        # ! [limitorder]

        order = Order()
        order.action = action
        order.orderType = “LMT”
        order.totalQuantity = quantity
        order.lmtPrice = limitPrice
        # ! [limitorder]
        return order

Disclosure: Forex

There is a substantial risk of loss in foreign exchange trading. The settlement date of foreign exchange trades can vary due to time zone differences and bank holidays. When trading across foreign exchange markets, this may necessitate borrowing funds to settle foreign exchange trades. The interest rate on borrowed funds must be considered when computing the cost of trades across multiple markets.

Disclosure: Futures Trading

Futures are not suitable for all investors. The amount you may lose may be greater than your initial investment. Before trading futures, please read the CFTC Risk Disclosure. A copy and additional information are available at ibkr.com.
