Using Cincom Smalltalk for Retrieving Data from New IEX API Enhancements

Posted on in Categories Hidden Gems

This Hidden Gems screencast shows some of the new “investor’s exchange” or IEX API capabilities and how to use it with Cincom Smalltalk.

Contribution from Arden Thomas, Cincom Smalltalk Product Manager

In some recent hidden gems, we brought together a number of earlier topics, such as using the DomainMaster for building and connecting applications together, custom views for displaying custom drawings, parsing JSON and creating objects, using HTTPS and making web API calls to retrieve data.

One web API that we used in these examples was the “investor’s exchange” or IEX API.  Recently they have expanded and added many new API calls. This Hidden Gems screencast shows some of these new capabilities and how to use it with Cincom Smalltalk. Investors Exchange (IEX) is an independent exchange started by Brad Katsuyama and was created to offer a transparent and fair exchange in the stock market.

The need for this was a topic of Michael Lewis’ financial drama, Flash Boys: A Wall Street Revolt. In this book, Lewis wrote about the rigging of the stock market by high-frequency traders, which allowed these traders to “front run” orders ahead of others. Flash Boys also focuses on the creation of the IEX, which was aimed at eliminating the advantage of those high-frequency traders. This story has gained so much popularity, that Netflix recently acquired the movie rights to this book
