It won’t work out of the box but we’ll be adding another intraday data provider in the next version. Who’s your provider?
The biggest issue with supporting arbitrary third-party data is that QuantRocket depends on a rich securities master database to link everything up, including at minimum an unchanging security ID, the currency, the exchange, etc. Also, with intraday data, good performance depends on a good storage design and on the software optimally using that design, which again makes arbitrary data a bit more challenging. These are solvable problems, though.
If this makes or breaks your purchase decision, email me privately (brian [at] quantrocket [dot] com) and we can explore options.
