Our Tools

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.

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.



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.

The API access provides on-demand enterprise access to our point-in-time factors and simulation engine. Use your preferred platform (Jupyter Lab, PyCharm, etc.) to run your quantitative research tests. And rest assured you can rely on our quality FactSet data and our powerful simulation engine.

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.
