A quick visual check of where Open Drives have occurred.
An Open Drive is when the first 30min period of the day also marked the high or low of that 30min period.
i.e. the day started with a sign of strength.
I will come back to this later
It now correctly identifies all open drives, but it will only color the bar when viewing on the 30min chart.
I will see if I can fix that
