Back in January, I wrote about Quantopian, the Spark-backed startup letting a community of quants build and share trading algorithms for the stock market. Today, the Boston-based company announced the launch of its new live pilot, which lets users simulate trading against a live market.

From the release:

Paper trading allows users to test trading algorithms against live market data, providing yet another tool for developing and optimizing algorithms. With the introduction of Live Trading, Quantopian provides a complete end-to-end platform for developing, testing and trading with financial algorithms. Initial access to Quantopian Live Trading will be provided to a select group of users through a pilot program, with open public availability later this year.

As I mentioned last time, the company does at some point want to support actual trading, but for now this is just about testing assumptions. The company raised $2 million in January.
