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.

Catatan Rilis:

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

Catatan Rilis:

More precise profile value calculation

Catatan Rilis:

Fix width with disabled history/last profiles

Catatan Rilis:

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

Catatan Rilis:

• 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.
  

Catatan Rilis:

Fix "screenshot"

Catatan Rilis:

Replace green color by teal

Catatan Rilis:

Add volume point of control (VPoC) as a line

Catatan Rilis:

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

Catatan Rilis:

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).

Catatan Rilis:

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

Catatan Rilis:

Fix preview chart

Catatan Rilis:

Fix the calculation of the first bar.

Catatan Rilis:

Highlight peak volume in a profile

Catatan Rilis:

Maybe fix for profile disappearing

Catatan Rilis:

Draw a profile using labels

Catatan Rilis:

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