Adding Standard Deviation & Color to watchlist, coding help please!

[DGreenleaf17]

Question, I was wondering if someone would be able to code a custom column for me, that when a stock is 2 standard deviations or more away from the mean, that column would turn "Green" and if it was within 2 standard deviations the column would remain "Black".

Been scouring the internet to find something like this and I have had no luck, would really, really appreciate any help with this.

Ps- been developing a plan for swing trading with this, and if it works, I would love to come back and share it.

Thank you!

What would be the original source for the standard deviations? For example, VWAP has its own 2 standard dev. Same goes for Bollinger Bands.

Just using the StandardDevChannel study within ToS, 21 length, while on a (30 day, 30 minute) chart. Within the study it has a upper, middle and lower line, I was hoping someone would be able to to figure it out if you could coincide the colors if it was 2 SD or more away.
