Step 2: Download the Software for Interactive Brokers
Trader Workstation (TWS):
For Interactive Brokers, TWS is the main trading application. The TWS API connection is made via it.
IB Gateway:
This is TWS’s lite version which is mostly used in dedicated algo trading setups.
Step 3: Enable API Access
Start either TWS or IB Gateway.
Go to Parameters > API > Parameters.
Check Enable ActiveX and Socket Clients.
Adding a trusted IP is a more secure way.
Step 4: Decide which programming language to use
The IB API has a broad language support. In most instances, it is proposed to novice users, as it is easier than others and many supporting libraries, including ib_insync and tws-api, are available for it.
What’s Available on IB API
- Real-time market data
Includes access to bid prices, ask prices, and volume, among others.
Example Use: Using the price of stocks to make auto buys.
- Historical Data
Allow to download data of a given stock’s price in the past in order to test trading styles.
Example Use: You may apply a mean-reversion strategy with the use of historical prices of some stocks.
- Managing and placing orders
Participating in the placing, correcting and cancelling of orders could be automated.
Example Use: When the price reaches a certain point, you can make a stop-loss order.
- Account Overview and Portfolio Information
Find out the amount of money in an account, the margin that is available, or what the portfolio consists of.
In other words: Change the proportions of the components of your portfolio automatically.
- Contract Specs
Find information for a particular security including its symbol, exchange and the kind of contract.
In other words: Get contract details for a futures contract or other futures instruments.
How These Algo Trading Strategies Work
Arbitrage Strategies
Bid on the price of an asset on different exchanges that are not the same at the same time.
Market Making
Add liquidity on the market by placing buy and sell orders at a time.
Trend Following
Adopt simple moving average or breakout strategies.
Pairs Trading
Find correlated and interrelated instruments or assets and trade them on the reversal when their price relationship deviate from normal.

Automate the processes of stop-loss and take-profit orders to lessen the common risk.
Guidelines for Accessing the IB API
Test in a Simulated Environment
Before placing any real funds, make sure you test your methods and algorithms out on an IB paper trading account to ensure that they will work well.
Handle API Limitations
In its APIs, Interactive Brokers imposes a limit on the number of actions (request rates), which can be performed on all API requests. The existing code should be improved to meet these requirements.
Implement Error Handling
At times, connectivity might not work as intended, or API endpoints are delayed. Improper requests and misunderstandings also have their place. Make sure your algorithm can account for these situations.
Stay Updated
Always ensure that you use the relevant version of the API, if you want to have access to certain functions along with the other features.

ib_insync (Python):
A wrapper that makes it easier to access any area of the IB API including order submission and obtaining historical data.
TWS API (Official):
An SDK available for a number of programming languages that allows applications to interface with the IB Trader Workstation.
Third-Party Platforms:
Products such as QuantConnect and NinjaTrader offer IB integrations and a lot more features.
Drawbacks and Limitations
Complexity
The pre-trading setup and the API documentation may baffle new developers or novice users.
Optimal Latency
IB exposes itself to its clients with super low latency but it is probably not the best fit for ultra-high frequency trading.
License
Your algorithm has to ensure that your algorithm follows the laws of your region.
Wrap Up
Across all interactions that exist within the Interactive Brokers, the one that stands out the most for algorithmic driven traders would be its API option.
