Is the Research environment a paid one or is it free for everyone?

Just created my account and want to learn further. Tried accessing the Research environment and got an error code >> 403 : Forbidden. Please help and thanks in advance.

@jomer damalerio First off, welcome to Quantopian but also sorry you are having problems connecting to the research environment. Once you have signed up, and logged in, it is free to use.

Quantopian's research environment relies on third party cookies and cross site tracking to protect user's intellectual property. Those two features must be enabled in your browser. Not having these enabled can cause issues like you are seeing.

Here are some browser specific instructions to maybe get research working:

  • Chrome: In preferences, find the cookies menu. Enable the switch that
    says "Allow sites to save and read cookie data (Recommended)", and
    disable the "Block third party cookies" switch.

  • Firefox: In preferences, find the cookies and site data menu. Check
    the box that says "Accept cookies and site data from websites" and
    make sure the box that blocks Third-Party Cookies is unchecked.

  • Safari: In preferences, go to the privacy menu. Make sure cross site
    tracking is unchecked.

If none of these things work, try disabling all extensions, and re-enabling them one a time to find which one is causing issues. If you find one that is causing the Quantopian site to break, try whitelisting and Those are the two domains that Quantopian uses.

There may be other issues with your network or computer firewall or simply that your browser is not refreshing after settings were changed and working from cache. If all else fails contact Quantopian support (the link at the bottom of this page).

Hope that helps!
