Session Opens - Asia, London, NY - Vtrend

This script is designed to show the market session opens, for Asia, London and New York.

I couldn't find anything that fit my requirements so I decided to code one up!

You can either have symbols below, LO, AO and NYO - or background colors representing open times.. Or indeed both!

There are no alerts currently coded in, will update this one if i get enough requests.

Timeframe wise, works best under 1 hour, will not plot above that.

Also it does not plot the weekend open times.
