I have provided the options to

• To show/hide all the important metrics related powertrend in a table.
  
• Background color can be shown on charts. It can be toggled as well.
  
• You can also modify the inputs for EMA and SMA
  

This script is supposed to be used on a daily chart however, it will work on other timeframes as well.

Notes de version:

1. Fixing EMA and SMA count logic.
   
2. Fixing summary table used of the correct value for Count(21EMA > 50SMA) row
   
3. Formatting recent high to show only two digits.
