1.
in example , i would like test only selected days from last 2 Years , BarPeriod is 1 Min.
in fact i can match selected days in array like 20190305, 20190412.....

How-to Test it without load complete history and test 2 Years BarBybar? . Any way to SKIP load history between selected days?

2. Is possible Plot selected days only ?

For skipping history loading except for selected days, the simplest way is a small script that writes a special history file that only contains those days.
