Alpha Streams is a global marketplace where Quants and Funds meet. Quants offer their alpha (algorithms) for licensing, and Funds can quickly locate crowd-sourced strategies that fit their target criteria. QuantConnect acts as an independent third party to verify the strategy performance, and run it out of sample in our production environment on live market data.

Alpha Streams licensing is performed with a monthly subscription, prorated on a daily basis. Funds can manage their subscriptions programmatically, licensing your Alpha as their models require. QuantConnect directly charges the funds a 30% fee for reviewing, hosting, and serving the algorithms. Charging funds directly ensures as much licensing revenue is passed back to you, the creator, as possible.
