Guys thanks so much for your work! I have found you guys as I have been very dissapointed with the quality of backtest data on other platforms. I know this as the bot I use to capture data for any type of chart on live always saves a lot more data than when I run it as a backtest. This applies even for range pip charts!! Anyway I have built a generic AutoML framework by abstracting the C# ML.NET framework that can build complex models in minutes on GB of data without any copy and paste of code as its all type based. With my system a trader can select what fields they want to use to build models and they can train and test models themselves. However I have only done this for one of the common retail platforms. Maybe you guys might like to interface this framework with your systems?
Here is the link that explains my framework https://genericml.odoo.com/
