matrixx Global Sessions + Good/Premium Spread Zones

Simple (enough) Script that allows you to visualize the major trading sessions, with some QoL stuff, Includes a "Monday Open" bar for reference when zooming out.

By default no one 'session' is turned on; instead, we have;

• Good Zone - where spread tends to close up enough for (me) to trade in the 1-minute timezones
  
• Premium Zone - where the tightest spreads tend to happen and I (you?) can get more aggressive with Stop Losses, and moment-to-moment trade accuracy.
  
• The Monday Open - for reference.
  

You are able to go into the settings and turn these on and off at will, making any combination of 'zones' you prefer, and can colour code them, as well.


Points of Difference;

• You can turn on and off any group or set of sessions for an overview;
  
• Additionally, this is coded so that if there is a "Daylight Saving" or other localized timezone shift, it should be reflected correcty, as timezones are calculated based on each sessions' data, not arbitrarily with +/- as most of the other scripts that do similar to this one.
  
• Monday Open
  
• you can toggle sessions, or instead toggle the 'off hour' zones, at will
