ICT Anchored IPDA Ranges

This script is an anchored variation of my "ICT IPDA Look Back" script. Similarly, it calculates ICT's daily IPDA look back time intervals and their respective discount / equilibrium / premium; however, it also applies the Forward Cast IPDA daily ranges.

The Forward Cast can be used to estimate the time at which IPDA might initiate a change in institutional order flow. This depends on several factors such as time of the year, and time of daily structure break.

> IPDA Basics:

• IPDA stands for Interbank Price Delivery Algorithm. Said algorithm appears to be referencing the past 20, 40 , and 60 days intervals as points of reference to define ranges and related PD arrays.
  
• Intraday traders can find most value in the 20 Day Look Back box, by observing imbalances and points of interest.
  
• Longer term traders can reference the 40 and 60 Day Look Back boxes for a clear indication of current market conditions.
  

Thanks to @atradesdaily for the suggestion.
