What is algorithmic investing?

Algorithmic investing has long been a high-priced, secret weapon used by Wall Street to conquer emotional biases and beat the market. Quantopian brings the power of algorithmic investing into your browser to level the playing field.

Algorithmic investing permits you to incorporate more data in your strategy than you could ever include on your own. Algorithmic investing prevents you from making the emotional trading errors that we’re all prone to make. You can test your algorithmic strategy before you put any money on the line and save yourself from costly errors.

Spend time on new ideas
rather than manual operations.
Make decisions based on data
and execute without emotion.
Test before you invest.
Vet systems before using real money.
Autopilot for your investments.
Your strategy, automated.
