Thanks a lot for helping me with this. I have attached the image to explain the indicator.
I have also attached the "flimbo_daily_highlow" indicator for your reference.
I need two separate indicator which mark the high low at [url removed, login to view] and [url removed, login to view] gmt starting with US close (5pm) 21.00GMT.(it could be one indicator which mark the two set of highs & lows)
Indicator 0030 - 21:00GMT to 00:30GMT (Blue colour)
Indicator 0330 21:00GMT to 03:30 GMT (Green Colour)
If you could explain me how I can change the timings, than I can modify the indicator when daylight saving starts and ends.
