Free historical data limitations

Hi,

Complete newbie. I just want to test that my assumption is true:

Can I backtest my algo on historical US futures data from 2009 - for free?

Or do I have to buy this data?

Update Backtest








Correct through the website you can backtest using it for free at the moment! We might charge for this feature at a later date. You can also download FX and CFD data for free from the Data Library which you can use with the open source project.

Daniel,

You can find an example of how to download data from the QC data library in the open source project here: https://github.com/QuantConnect/Lean/blob/master/Api/Api.cs#L574

This is only for FX and CFD data you have already purchased through QuantConnect. This method also assumes you have set your "job-user-id" and "api-access-token" in config.json.

Hi Andrew,

Thank you for the reply.

Do we have a RESTful API endpoints  for this, i see reference to some C# code? our platform if written in PHP  will be practical to access RESTful API endpoints  using our "job-user-id" and "api-access-token" in config.json.
