Poor man's volume profile

This is an attempt to get something more or less similar to the volume profile for free.

The code is generated using a template. To change the settings, you may need to regenerate the code. The code has a link to the repository with the template.

Release Notes:

• Decouple width of history and recent profiles
  
• Make profile value independent from profile height
  

Release Notes:

More precise profile value calculation

Release Notes:

Fix width with disabled history/last profiles

Release Notes:

• Fix width with disabled history/last profiles
  
• Do not clip recent profile
  

Release Notes:

• Fix server study error by adding max_bars_back.
  
• Rewrite code to make it simpler but slower.
  
• Add option to use custom ticker as volume source.
  

Release Notes:

Fix "screenshot"

Release Notes:

Replace green color by teal

Release Notes:

Add volume point of control (VPoC) as a line

Release Notes:

• Use nz() instead of own nan_to_float()
  
• Fix history block offset
  

Release Notes:

Volume clusters (those called historical blocks) have been moved to a separate study, see "Poor man's volume clusters".

Study has been significantly optimized. Now you can set the profile size up to 500 bars (limit can be lifted if you change max_bars_back in the source code).

Release Notes:

Correct way (I'm sure of it) to calculate row value. It could be wrong.

Release Notes:

Fix preview chart

Release Notes:

Fix the calculation of the first bar.

Release Notes:

Highlight peak volume in a profile

Release Notes:

Maybe fix for profile disappearing

Release Notes:

Draw a profile using labels

Release Notes:

* Fix "Invalid symbol" warning when the custom volume source is enabled.
