Project description:
"I am looking for an experienced Pine Script (v5/v6) developer to extend an existing TradingView indicator.

Indicator: Volume Profile and Volume Indicator by DGT
[login to view URL]

Currently, the indicator supports two calculation modes for Profile Lookback Range:
1. Fixed Range
2. Visible Range

I need a third mode to be added:
3. Custom Time Window Range

When Custom Time Window is selected:

1. User Inputs (new settings)
Add new inputs in the settings panel:
- Start Time (Example: 15:45)
- End Time (Example: 07:21)

2. Logic
The indicator should calculate the Volume Profile only inside this selected time window:
- Works across sessions (example: from 15:45 of the current day until 07:21 of the next day).
- Must handle time windows that cross midnight correctly.
- Should work on any timeframe (1m, 5m, 1h, etc.).

3. UI Requirements
- Clean integration into existing settings.
- New inputs should be active only when "Custom Time Window" is selected (if possible).
- Do not break existing Fixed Range and Visible Range behavior." (client-provided description)
