  Hi all, once i finish work at 6 in the weekday i want to see what the market has done in the previous say 3 hours and if the conditions are met between 3-6pm the screener to show these stocks, is there a line of code to define previous x amount of hours?

  You can scan conditions backwards using bars as rerefence, 1 bar, 2 bars, up to 254 bars (1024 on PRT direct).

  On a 30-minute chart, 3 hours is 6 bars, so you can use summation[6] to check if any condition was met in that time range:

  Cond1 = ... Cond2 = ... Cond3 = ... Cond = Cond1 AND Cond2 AND Cond3 SCREENER[summation[6](Cond)]

  1 2 3 4 5

  Cond1 = ... Cond2 = ... Cond3 = ... Cond  = Cond1 AND Cond2 AND Cond3 SCREENER[summation[6](Cond)]
