Learning Python in the Real World, with IBKR API Support

Picture this: you set up IBKR filters every morning to scan the markets for the top three companies with certain key intraday attributes. You would like to run these scans all day to ensure that you take advantage of opportunities whether or not you are sitting at your computer, but you also need time to trade.

Your situation is ripe for an algo, and IBKR’s APIs make building algos relatively easy. Once your algo is done, you’ll never have to run those scans manually again.

Andrew Wise, IBKR API Support Specialist, says that some traders hesitate to try writing their own programs because they have not yet used the languages IBKR APIs work with – Python, Java, C#, C++, VB, and countless third party projects that provide support in R, Ruby, or the Python alternative, IB-insync and more. He says using them is easier than you might think.

“The best way to learn Python, or any other languages with IBKR APIs is step-wise. Before you do any programming, review our tutorials. Break down every action your program needs to execute. Python uses bits and pieces of existing programs to build new ones, so you won’t be starting from scratch. Also, in TWS you can create a paper account and test what you’re doing without risk. If there’s a mistake, just hit reset, make adjustments and try again.”

IBKR APIs are built for “do-it-yourself” clients, and Wise says there are primarily two kinds: traders who feel they don’t know enough about programming and programmers who feel they don’t know enough about trading. The first kind is more common, and though Wise says it can take a little effort to show them they can do it, the results make it worth their time.

He cites a real-world example.

“I had a client who was a sophisticated trader, an expert at point-and-click execution. He’d developed a ‘rinse-and-repeat’ strategy, which he knew so well he hardly had to think about it. but executing it manually took time. He called us to ask if automation could help.

“When we started working together, he quickly got frustrated and gave up almost immediately. The funny thing was, the programming wasn’t the problem. It was the trading. Before you start you have to map out exactly what an algo will need to do, and when we started to do that, it was as if he’d never traded before. It turned out that he’d never had to learn certain parts of the underlying mechanism of a trade because TWS ran it all in the background.”

A few weeks later, he called back, ready to try again.

“We walked through some programming basics. The light bulb went on when he reviewed the tutorials. Once we mapped out the trading process, we started building the algo using Python, which he picked up faster than he expected. After that, it was trial and error. These days he is very satisfied and confident that he can keep refining what he’s done.”

Wise adds, “We designed our APIs so that using Python to build an algo that executes your strategy is the easier part. As you’d expect, the harder part is developing the strategy.”
