Mark % Change Column


New member
I need help getting the code for the Mark % change from the previous day close for Pre-Market ... Every code I've used, I on;y get results after the open. I also want to be able to change the background color.

Thank you and Happy Trading!

on the marketwatch tab, i have a column for Mark % change and % Change. one shows afterhours change and one shows day performance only. is there a way to create a custom column to show (Mark % Change - % change) (difference between the two) to show afterhours performance only? is this possible?

You would need to use some time constraints factored into the script to calculate only trade hours change from within an extended hours enabled script to get the trading hours change...
