Buy Signal with FVG Confirmation (1h,15m,5m)

Key Changes:
FVG Conditions Added to buySignal:

The buy signal now requires FVGs on all three timeframes (1h, 15m, 5m) in addition to your original criteria.

buySignal = ... and fvg1h and fvg15m and fvg5m

Simplified FVG Detection:

The detectFVG function now only returns the fvgBullish boolean (no need to return price levels).

How to Use:
Apply to 1-Hour Chart:

The script works best on a 1-hour chart since it combines daily, hourly, and lower timeframe (15m/5m) logic.

Interpret Signals:

A green triangle appears below the price bar when all conditions align, including FVGs on 1h, 15m, and 5m.

Use the shaded FVG zones (teal, orange, purple) to visually confirm gaps.

Set Alerts:

Create an alert in TradingView to notify you when the buySignal triggers.

Important Notes:
Multi-Timeframe Limitations:

Lower timeframe FVGs (15m/5m) are fetched using request.security, which may cause slight repainting on the 1-hour chart.

FVGs are evaluated based on the most recent completed bar in their respective timeframes.

Strategy Strictness:

Requiring FVGs on three timeframes makes the signal very selective. Adjust the logic (e.g., fvg1h or fvg15m) if you prefer fewer restrictions
