Watchlist column-Breaking Pre market high

[Kitten-massacre]

What I’m wanting is to have a watchlist column that tells me how much higher the price is currently at compared to that mornings pre market high.

If pre market high was $3.50, and the price at market open shoots to $7, then the watchlist column would read 200 (%). If the price drops to 1.25, then it would read 50. If it stayed at 3.50 it would read 100..this is how I’m assuming it would look anyway. I’d just like to at a glance quickly reference if the stock on my watchlist is over pre market high or not. Thank you to any who try to help!
