Easier. Better. Faster.

Universe Limit

Your algorithm can price and trade 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.


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.

Lookback Prices

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.
