regarding back testing

[rose123]

is it possible to back test a strategy in long term data like 10 ys , 15yrs , 20 yrs.

Currently it is not possible.
In future versions, the developers are going to add such an ability. I can't promise backtesting in terms of one-minute simulation. But simulation like one-hour most likely will be available.

You would be able to do this even now, if you break this period into smaller elements.
And then reconstruct the whole period.
