Volume profile zones

Hi all!

This script calculates and shows the volume profile for the range of a higher timeframe candle. It then shows support or resistance (/supply or demand) zones based on the volume profiles with the most volume. The defaults are just my preferred settings so feel free to play with them! Also feel free to let me know about bugs and features. I already have a list of features to make, e.g.:

• base on pivots
  
• more info zone calculations, e.g. breaks and retests, virgin point of control etc.
  
• add alerts
  
• get rid of getPriceLevels()
  
• get rid of _barVolumeProfile prefix
  
• handle realtime
  

...

Best of trading luck!

Hi all!

Here's an update with A LOT of changes. Not all will be listed, but I will try to list the most important once below.

• Default settings are changed to match my trading with daily timeframe and volume profiles/zones per month 1 year back. Feel free to change them to suit you.
  
• Volume profiles are now 'live' and will update automatically.
  
• The last range will show a volume profile even if it's incomplete.
  
• Alerts are only possible to set if 'Last range bar index' is set due to var/varip and unknown pine history error.
  
• You can check 'Last range bar index from end' to let the indicator be active from the end, this is really useful when switching between securities and not having to figure out the bar index every time.
  
• It is now possible to visualize the current active range
  
• Alerts can be set for bull or bear direction (or both).
  
• ...
  

Best of trading!
