First Presented FVG
Summary: First Presented FVG Indicator
This is aPine Script® TradingView indicator that identifies and visualizes the first Fair Value Gap (FVG) that forms within configurable time windows during a trading session.
What it Does
1. Detects FVGs: Uses the classic 3-candle FVG definition:
- Bullish FVG: When low[0] > high[2] (gap up)
- Bearish FVG: When high[0] < low[2] (gap down)
2. "First Presented" Logic: For each configured time slot, it captures only the first qualifying FVG that forms—subsequent FVGs in that window are ignored.
3. Visual Display:
- Draws a colored box spanning from detection time to session end
- Optional text label showing detection time (e.g., "9:38 Tue FP FVG")
- Optional grade lines at 25%, 50%, and 75% levels within the FVG
