Create Volume Profile Indicator for NinjaTrader and TradingView (with POC, VAH, VAL, and Extended Lines)

Hello,
Hope you are doing well.
I need urgent help with a project, and if done successfully, there will be long-term work available.

Requirements:

1. Accurate POC Calculation:

• Identify the POC (Point of Control) as the price level with the highest traded volume within a selected session or time range.

• Allow users to select volume source: trade volume, tick count, or bid/ask volume.

2. Correct Value Area Calculation (68%):

• Calculate and display Value Area High (VAH) and Value Area Low (VAL) covering 68% of the total volume, centered correctly around the POC.

3. Configurable Inputs:

• User input for session/time range selection.

• Volume source selection (trade volume, tick count, bid/ask volume).

• Option to display only the POC or the full profile (POC + VAH/VAL).

4. Visual Rendering on Chart:

• Draw a horizontal line for the POC (red).

• Draw horizontal lines for VAH and VAL (blue or user-defined color).

• The indicator must be lightweight, fast, and not clutter the chart.

5. Extended Lines Feature:

• After drawing a range on the chart, the volume profile should display with 5 important levels, and these lines should extend into the next day’s session.

Platforms:

• NinjaTrader (NinjaScript)

• TradingView (Pine Script)

Attached is a volume profile example from TradingView for the expected output.
