NYSE extended session background

This script adds background to the chart to highlight different time areas in any chart.

The time areas are in relation to the open/close time of NYSE , both regular and extended session.

The background colors are the following by default:

• NO COLOR : NYSE is open
  
• DARK BLUE : NYSE is closed
  
• LIGHT BLUE : NYSE post market session
  
• ORANGE : NYSE pre market session
  

In addition, previous day close price line is shown during extended and closed sessions (orange line).

This script is useful to visualize any chart in relation to the NYSE timetable.
