## Key Gamma Levels Guide

### Total GEX — Market Regime Indicator

The single most important indicator. Determines whether to be a premium seller or buyer.

- **+GEX (Positive Gamma)**: Market makers dampen volatility. Sell rallies, buy dips. Price gravitates toward Max Pain.
  - **Strategy**: Sell premium — Iron Condor, Butterfly, Short Straddle/Strangle
  - **Timing**: Afternoon entry preferred (maximize theta earned)

- **-GEX (Negative Gamma)**: Market makers amplify volatility. Sell dips, buy rallies. Trending/whipsaw conditions.
  - **Strategy**: Buy premium — Long Straddle/Strangle, Reverse Iron Condor
  - **Timing**: Morning entry preferred (minimize theta cost)

### Put/Call OI Ratio — Sentiment

- Below 0.66 → Bullish sentiment
- 0.66–0.68 → Neutral
- Above 0.68 → Bearish sentiment

### Call Wall — Resistance

Strike with the highest absolute call gamma. Market makers sell underlying as price rises toward it, creating resistance.

### Put Wall — Support

Strike with the highest absolute put gamma. Market makers buy underlying as price falls toward it, creating support.

### Call % / Put % — Distribution Balance

Percentage of GEX distribution above/below spot price. Extreme imbalance signals mean-reversion opportunity.

### Call Center / Put Center — Breakout Signals

Median of GEX distribution for calls and puts respectively.

- Price breaks above Call Center → Bullish continuation signal
- Put Center far below spot → Bearish warning (downside risk)
- **Distance** (Call Center − Put Center width) = trading range gauge

### Max Pain — Closing Price Predictor

Strike where option holders lose the most at expiry.

- **+GEX days**: Strong closing price predictor. Build strategies around it.
- **-GEX days**: Weak predictor during session. But expect convergence in final 15–30 minutes (dealer hedging wind-down).

### Gamma Flip — Regime Boundary

The strike where net gamma crosses zero.

- Price above Gamma Flip → Mean-reversion regime (low volatility)
- Price below Gamma Flip → Trend-following regime (high volatility)

## Option Greeks Reference

### First-Order

| Greek | Symbol | Measures | Typical Range |
|-------|--------|----------|---------------|
| Delta | Δ | Price sensitivity | Call: 0 to 1, Put: -1 to 0 |
| Theta | Θ | Time decay (per day) | Usually negative for longs |
| Vega | ν | IV sensitivity (per 1% IV) | Always positive for longs |

### Second-Order

| Greek | Measures | Formula | Trading Use |
|-------|----------|---------|-------------|
| Gamma (Γ) | Rate of delta change | ∂Δ/∂S | Peaks ATM near expiry |
| Vanna | Delta-IV sensitivity | ∂Δ/∂σ = -N'(d₁)·d₂/σ | Critical for earnings/FOMC |
| Charm | Delta-time sensitivity | ∂Δ/∂T | ATM delta decays fastest near expiry |

## Options Calculator Usage

### Single Option
1. Select Call or Put
2. Enter: Underlying Price, Strike, Days to Expiry, IV, (optional) Market Price
3. View calculated price and all Greeks
4. Use sliders to simulate time decay and IV changes

### Multi-Leg Strategy
1. Click "Add Leg" to build combination
2. Use strategy templates: Bull Call Spread, Iron Condor, Butterfly, etc.
3. Adjust strikes and quantities
4. View combined P&L chart with breakeven points highlighted

### Simulation Sliders
- **Time Remaining** (0%–100%): 0% = expiry, 100% = current. Watch theta decay reshape P&L curve.
- **IV Change** (-50% to +100%): Model vol crush or expansion impact on strategy value.

## Beginner's Guide: How to Trade Using GEX

### Step 1: Check the GEX Regime
Open the dashboard and look at **Total GEX** first. This single number determines your trading approach for the day:
- **Positive (+GEX)**: Market is stable. Sell premium. Iron Condors and Butterflies work best.
- **Negative (-GEX)**: Market is volatile. Buy premium. Straddles and Strangles have edge.

### Step 2: Identify Key Levels
Look at **Call Wall** (resistance) and **Put Wall** (support). These are the price levels where market maker hedging creates the strongest forces. Plan your trades around these boundaries.

### Step 3: Choose Your Strategy
Use the **Smart Strategy Engine** tab — it automatically analyzes the current GEX regime, price position relative to key levels, and suggests specific strategies with example strikes. No manual analysis needed.

### Step 4: Manage Risk with Max Pain
On +GEX days, **Max Pain** is highly predictive of the closing price. Use it as your profit target. On -GEX days, expect convergence to Max Pain only in the final 15–30 minutes.

### Step 5: Review with Replay
After market close, use **GEX Replay** to review how levels evolved throughout the day. Compare your trades against the gamma levels and refine your strategy for next session.
