Goldman's Trading Floor is Going Open-Source - Kind of" was published in the New York Times back in April 3, 2019. The idea of accessing and possibly contributing to a Goldman open-source project on asset pricing, risk management, and data analysis is intriguing. I followed up today and was unfortunately disappointed.
The code is on github. You immediately run into a wall while looking over a sample notebook (link, as example) and trying to run the code. The sample notebook fails, since it requires a data subscription. I didn't follow through and email Goldman about pricing, but you are welcome to do so here (link). And since the code is structured to use with the Marquee platform, it's hard to justify using that at all unless you already have a Marquee subscription.
Overall, Goldman's move feels like an advertisement for their data platform and hope for their customers doing some free bug fixes for them. If I were to use my own data from other sources, I might as well use other pricing libraries or write my own. The pecuniary and time cost is too high for the benefits.
As for actionable advice for Goldman, they should consider making a very limited part of their marquee platform for free so that some of their sample notebooks would work. They can attract more engagement by making limited data like the last 3 months of stock prices on the SP500 available. That data is available for free on Nasdaq.com or Yahoo.com with manual downloading. To be fair, I don't have Goldman's marketing and sales data -- perhaps the elasticity isn't there to make such a move profitable.
