How to Code a Limit Order in Python

Articles From: Interactive Brokers
Website: Interactive Brokers

The Limit order is used to buy or sell securities, derivatives or cash at a specified price or better. It is designed so that if the order gets filled, it will not be executed at a price less favorable than the “limit” price you specified. However, this order type does not guarantee an execution.

Let’s refer to IBKR API GitHub to learn how to code this in Python.

order = Order()
order.action = action
order.orderType = “LMT”
order.totalQuantity = quantity
order.lmtPrice = limitPrice

The products supported via this order are: Bonds, EFPs, Forex, Futures, FOPs, Options, Stocks and Warrants.

Visit our GitHub guide to download the API sample Testbed, and review the Python code for additional order types: http://interactivebrokers.github.io/. The sample syntax is stored in the OrderSamples.py file.

Stay tuned for IBKR order type articles. See the previous installments in this series:
