Data is Everything

Your backtest is only as accurate as the data it is based upon. TuringTrader supports high quality data feeds including Norgate, Tiingo, Yahoo, and FRED. When that’s not enough, you can easily bring in your own data, be it from a web source, a data model, or a local CSV.

Indicators Done Right

Indicators are at the core of technical analysis. But most often, their use is unintuitive, and riddled with limitations. Using TuringTrader’s ‘automagic’ indicators is as simple as making a function call. You can daisy-chain them, apply them to a whole universe of assets at once, and even mix and match indicators when they are running on different bar periods. TuringTrader includes a comprehensive library of standard indicators, but you can easily implement your own, if needed.
