Shows the opening range for morning and afternoon session. 9:30-10:00 and 1:30-2:00 EST.
It also has the option to add 0.5 and 1 standard deviations in both directions or range extensions.
Note: If you are having weird scaling issues when using this script, especially with the extensions, go to the settings in the bottom right of the chart. It is where the time and price axis meet which is bottom right by default. And then make sure "Scale price chart only" is enabled.
