Pine Script Development Request: Customizable Fair Value Gap (FVG) Indicator

I’d like a fully customizable Fair Value Gap (FVG) indicator with the following functionality:

⸻

1. Multi-Timeframe Detection Settings

Allow users to define up to 5 timeframes, each with the following components:
	•	Dropdown Menu: Select any TradingView timeframe (e.g. 1W, 1D, 4H, 1H, 6H, etc.)
	•	Custom Label Field: Allow user to input a custom label (e.g. “W” for Weekly or “Daily” for 1D)
	•	Checkbox: Enable or disable FVGs from that specific timeframe

These should be named:
	•	Timeframe 1
	•	Timeframe 2
	•	Timeframe 3
	•	Timeframe 4
	•	Timeframe 5

Important: I need to be able to see Higher Timeframe (HTF) FVGs while on a Lower Timeframe (LTF) chart.

2. FVG Detection Settings
	•	Wait for candle to close to identify FVG? (checkbox)
	•	Filled FVG Type (dropdown with two options):
	•	Body Close
	•	H/L (High/Low — by wick)
	•	Delete boxes after fill? (checkbox)
	•	Extend boxes? (checkbox)
	•	Hide FVGs lower than enabled timeframes? (checkbox)

⸻

3. Detection Range and Box Length
	•	Max bars look back to find and display FVGs (custom number input)
	•	Length of boxes (how far the FVG should extend in bars) (custom number input)

⸻

4. Visual Configuration Options

Box Visuals:
	•	Bullish FVG Box Color (color picker)
	•	Bearish FVG Box Color (color picker)

5. Alerts
	•	Add the ability to trigger an alert when price touches FVG box of specific time frames I choose (ability to choose up to 3 time frames), regardless if it’s bearish or bullish.
	•	The alert message should include:
	•	The timeframe of the FVG
	•	Whether it was bullish or bearish
	•	The price level where it was touched
