Quantopian on Github: Open-Source Tools

In addition to the powerful platform that Quantopian provides, they have open-sourced some of their tools on Github which means they are able to be cloned for personal use and experimentation.

Their approach to algorithmic trading is very refreshing given the Wall St culture to keep all intellectual property (IP) secret – and rightfully so due to the competitive nature of the markets.

That said, Quantopian is approaching the markets as a crowd-sourced hedge fund and leverages the IP of many to construct profitable algorithmic strategies.

As a result, they are following the culture of many Silicon Valley to open-source their most common tools and social coding to improve upon them.

Chat with Traders #72: Trading Probability (Discovery Trading)

I enjoyed listening to Episode #72 with Rob from Discovery Trading, where he discusses his views on probability when trading the markets.

Although the interview is prefaced with a disclaimer regarding the scalping tactics used by Rob, I found his views on probability very interesting since they are relevant to risk management.

Kudos to Aaron for this interview and Chat with Traders, please keep up the great work!

Chat with Traders #75: Dan Aisen (IEX Stock Exchange)

I enjoyed listening to one of archived Episode #75 with Dan Aisen, who is co-founder of the IEX Stock Exchange.

IEX is a newer stock exchange which introduces features to minimize structural arbitrage tactics used by some High-Frequency Trading (HFT) firms and protect institutional investors.

During the interview, Dan goes into depth about market structure, HFT tactics and dark pool exchanges where IEX started out before being granted status as a stock exchange.

Dan also outlines his work in a detailed Quantopian blog post.

Kudos to Aaron for this interview and Chat with Traders, please keep up the great work!
