The genesis of this project was to create a POC library that would be available to deliver volume profile information via pine to other scripts of indicators and strategies.
This is a republish of an invite only script to open access
This is the indicator version of the library function.
A few points of significance:
- Allows the choice of reset of the study period, day/week or bars. This is simple enough to expand to other conditions - Bar count resets starting from the beginning of the data set (bar index =0) vs bars back from the end of the data set - A 'period' in this context is the time between resets - the start of the POC (eg. start of Day or Week) until it resets (for example at the beginning of a next day or week) - Automates the determination of the increment level rather than the user specifying ticks or price brackets - Does not allow for setting the # of rows and then calculating the implied price increment levels - When a period is complete it is often useful to look back at the POCs of historical periods, or extend them forward. - This script will find the historical POCs around the current price and display them rather than extend all the historical POC lines to the right - This script also looks across all the period POCs and identifies the master POC or what I call the Grand POC, and also the next 3 runner up POCs
- added error message if the symbol does not have volume - updated Auto Increment calculation - made showing the ranked chart data set POCs a display option
A note about volume calculations. If one candle traverses more than one increment/price level, the volume is divided equally between each price level traversed by the single candle, this should be a rare occurrence but it's important to note that all the volume is not placed at the last point of the price for the candle.
Can you post some charts with explanation to take entry? What are historical POC? How to use them? What is Grand POC and it's significance?

@sharewasi, there is public material on using points of control, i would be repeating much of what is in public domain. Grand POC is the highest volume across all periods examined, for example if u set for daily, the end of each day will have a POC, they make up the history POCs, the grand POC is the maximum of of all those days
