Get Access to
Advanced Screening
Ours is the most usable yet powerful stock screener available. You can use your own universe, rank with your multi-factor rank, and run backtests or rolling backtests. Many pre-built screens are available to help you get started.
Ranking
You can easily create multi-factor stock ranking systems and run performance backtests. Each factor can be weighted and ranked against all other stocks in your selected universe or GICS level.
Strategy Simulation
Test your hypothesis by running a realistic strategy simulation. A strategy is specified using an intuitive wizard to set up your money management rules, your universe and ranking, rebalance method, and the buy & sell rules. Once you are satisfied you can launch a live strategy to track real time performance and get buy/sell recommendations.
- Fundamental Charts
Go beyond price and visualize historical point-in-time data and trends using our extraordinary Fundamental Charting tool. We offer dozens of pre-built charts, which not only illustrate their powerful capabilities but can be supremely useful as you analyze a stock. Of course, you can also design your own charts using any fundamental, estimate, technical, industry data, or your own formulas.
- DataMiner
DataMiner allows you to run hundreds of operations with one click. Specify the operations using human readable instructions, with no programming skills required. The output is in plain text so it can be easily imported to other systems or reports. DataMiner is built on top of our API and can run on Windows, Mac or Linux.

Easy to use but powerful functions, backtesting & simulations. My results have been very good and could even be better if I would not try to second-guess my model.
