Naive Synthetic GEX & Midday Breakout

847
### Overview
The Naive Synthetic GEX & Midday Breakout Overlay is a multi-purpose intraday tool designed to combine options-market volatility regime tracking with systematic price-action breakouts.

It generates synthetic Gamma Exposure (GEX) levels to help traders identify whether the market is sitting in a Mean-Reverting (Positive Gamma) or Trend-Accelerating (Negative Gamma) regime, while simultaneously highlighting tight midday consolidation ranges.

### How It Works

1. **Synthetic GEX & Volatility Bands:**
- **Zero Gamma Line (Orange):** Built using an anchored Session VWAP (falling back to a 20 SMA if session data is unavailable).
- **Call Wall & Put Wall (Red & Green Lines):** Dynamically projected using a user-definable Average True Range (ATR) multiplier (Default: 1.5x ATR).
- **Dynamic Regime Background:**
- **Green Background:** Spot price is ABOVE the estimated Zero Gamma line (Positive Gamma / Low Volatility Regime).
- **Red Background:** Spot price is BELOW the estimated Zero Gamma line (Negative Gamma / High Volatility / Breakout Expansion Regime).

2. **Midday Consolidation & Breakout Signals:**
- **Time Filter:** Active exclusively during midday hours (11:30 AM – 2:00 PM EST).
- **Yellow Compression Zone:** Highlights periods where candle ranges shrink below 0.8x ATR while holding above VWAP, signaling institutional compression.
- **MIDDAY GO Signal (Green Triangle):** Triggers when price breaks out above the 12-bar highest high on expanding volume relative to its 20-period moving average.

### How to Trade with This Script

- **Filter Breakouts by Regime:** High-conviction intraday breakouts (or inverse setups like SQQQ) perform best when price is trading in a **Negative Gamma (Red Shading)** environment below the Zero Gamma Line, as dealer hedging accelerates directional momentum.
- **Midday Execution:** Look for tight yellow compression shading during the midday lull (11:30 AM - 2:00 PM EST). Enter on the green "MIDDAY GO" triangle when volume expands out of consolidation.
- **Profit Taking:** Use the dynamic Call and Put Walls as primary targets or rejection zones where price momentum is likely to stall.
