@run-out Hey that error has been solved. I want to code my program that is starts taking trade after 9:30(Market opens at 9:30). Timeframe = 1 minute
Condition is if close of any 1 minute bar after 9:30 is above the high range then buy at market price.
If close of any 1 minute bar after 9:30 is below the low range then sell at market price.
