Hi there,

You can use Bars.LoadMoreHistory() method to load more bars.

Best regards,

This method does not work on backtesting at the moment. If you need more bars for backtesting, you can start your bactesting at a previous date.

That's not a good solution you will have to change your code just for the sake of backtesting & optimizing if you use duration based calculations.

It's a solution when there is no other option. This will be enabled in backtesting in future releases.
