Terms and Conditions


At QuantConnect want to empower you with everything you need to design powerful algorithmic trading strategies. We believe algorithmic trading will be the future and you are pioneering the way forward. This is what drives us.

We have intentionally avoided conflicts of interest; such as taking conflicting investors, or revenue models where the real costs were hidden from you. Our revenue is from professional monthly subscriptions and brokerage client introduction revenues. We like to position QuantConnect as a member of your quant support team, taking care of fundamental engineering leaving you to focus on alpha.

By using QuantConnect (we, us, our) services (website, product, forums) you agree to the following terms of use.

Prohibited Activities

By using QuantConnect you agree you will not:

  • Copy or reproduce copyrighted materials provided on by QuantConnect or the community.
  • Attempt to gain access, hack, penetrate or abuse the system in anyway.
  • Download or distribute data we make freely available for back-testing. We pay for this data on your behalf. If discovered, unauthorized downloading and misappropriation can lead to account termination and legal action.
  • Spam or otherwise post offensive material in the community forums.
  • Upload any material which violates patent, trademark copyright or other proprietary rights of other third parties.
  • Attempt to reverse engineer, discover source code, reproduce any information or software obtained through the website or service.

Not Investment Advice

Nothing provided by our services should be interpreted as investment, legal or tax advice. We are not financial advisors, brokers or fund managers. None of the QuantConnect University, Strategy Library, third party content or shared algorithms on our service should not be interpreted as recommendations. These are educational materials provided for the development of your strategy.

The service provides ability to test ideas on historical data, however past performance is no guarantee of future results.

The QuantConnect service executes trades as directed by your algorithm, and you are solely responsible for its correctness and results. Occasionally in the course of executing orders the system generates additional trades (e.g. Crossing long-short generates two trades on some brokerages).

Intellectual Property

You own all content you submit or create through using QuantConnect. All content will remain private unless explicitly shared by you.

We know your intellectual property is valuable and do our best efforts to protect it and keep it safe. None of your code is ever distributed or used without your permission.

We never open or view raw project code. If you require help or technical assistance we will explicitly ask your permission: "Do you mind if I open the project ? ". Additionally, only two team members have root access to the database (Jared Broad, Gustavo Avil├ęs).

When you share a post or algorithm you grant QuantConnect and other QuantConnect users a perpetual, royalty free license to modify, distribute, reproduce and create derivative works of your content. By sharing content you confirm you have the right to do so.

The development environment, reports, forums style and trademarks are all the property of QuantConnect and may not be copied, modified, reproduced or sold without our written permission.

Live Trading Risks

By using our service you confirm you understand live algorithmic trading has many risks and QuantConnect is not held responsible for any losses incurred through using our service.

These risks include but are not limited to:

  • Design risks; errors in data, incorrect assumptions, logical program errors. Even if you designed a perfect strategy, past performance is no guarantee of future results.
  • Loss of internet connectivity; resulting in disconnections from brokerage, trades not placed, not seeing the results of algorithm, orders failing to be placed.
  • Poor design of algorithm; resulting in runaway strategies, machine gun orders, run-time errors halting program operation, failure to trade when expected, termination of the algorithm.
  • Unexpected market conditions; resulting in poor fill prices, rapid losses (flash crashes), late exchange openings.
  • Data issues; broken, dirty, delayed or intermittent data connections causing algorithm errors. This includes data inaccuracies (exchanges sometimes publish bad/fictional trades).
  • Execution issues; orders submissions, updates and cancellations could be rejected or delayed. Trades could be disallowed by authorities without warning.
  • Malicious activities; criminal activity could cause your algorithm to fail or your brokerage account to become compromised, leaking personal information, intellectual property or theft of your funds.

These events can cause the loss of all funds and holdings in your brokerage account. Algorithmic trading losses can occur faster than in manual trading and you should consult an investment professional to discuss these risks. You should continually monitor the operation of a live trading algorithm to ensure it is running properly.

Every time you use our service you agree that in all cases QuantConnect bears no responsibility for losses incurred, and offers no guarantees or expectations on your algorithm performance or stability.
