We have just launched Quantopian 2. This is an unusual release for us - we usually make more incremental changes. This release is a giant leap! Quantopian 2 includes many improvements, including:
- Universe Limit Removed: Your algorithm can reference all securities, not just a few hundred at a time. Price and volume data for any security is delivered to your algorithm, on demand. Removing this limit enables you to trade bigger baskets of securities. (Learn more)
- Faster Simulation: Backtesting is now 5x faster on average, and some algorithms are 50x faster. The fastest algorithms are ones that take advantage of Quantopian's scheduling function, and only load data and portfolio information when needed.
- More Accurate Stock Pricing. Lookback windows of historical data now use prices and volumes that are split-, merger-, and dividend-adjusted. You can now make accurate calculations of the returns of securities because the price information in the lookback window is fully adjusted. (Learn more)
We've prepared a special area for you to learn about Quantopian 2. Please review the information, and then give Quantopian 2 a try.
Please let us know if we can help you get going on Quantopian 2. You can reply to this thread, though it's probably best if you create a new forum thread for new questions. And, of course, please Contact Support if you need some help.
