Version 1.3 2018.06.11
There is an upgrade to allow your choice of color for the vertical lines and text. In addition, the mouse over of the vertical lines will display not only the date time of the vertical lines but also the vertical event text. Now the tool should be more usable.

TIP: I do not know if you have observed this, but this indicator clearly displays the opening and closing of each market. Each time, a sizeable market/s opens, the prices move significantly. This basically tells you when to enter the market with potentially high winning rates.
Version 1.2 2017.07.13
This version has the following enhancements:

1) Local time on the upper right corner to allow a quick glance at the current local time.

2) Update of the market local time open and close hours based on http://www.forexmarkethours.com/GMT_hours/02/.

3) Additional tooltip text on the vertical dotted line to include the local time. The reason for including this is to let a trader know what time locally to watch out for a trend change (which almost always happens) when a market opens or closes.
Version 1.1 2016.08.17
