I would like to display the range (High-Low) of the first bar of the trading day
on a 5 minute TOS chart. I would also like to add a user option to display the range
of the first 3 bars of the trading day as an alternative if it's possible. I know how to
display the result, I just need to know what script to use to identify the range for the
first bar or first 3 bars. I appreciate any suggestions.
Can you help answer these questions from other members on NexusFi?
