מעודכן Gamma Pressure
Gamma Pressure is a composite oscillator that estimates directional buying/selling
pressure in equity-index instruments (ES/MES, NQ/MNQ, SPX, NDX, SPY, QQQ, RUT,
IWM) by blending six independent, purely price/volume/volatility-derived
signals into a single -100 to +100 reading.
**⚠️ Important — read this first:** Gamma Pressure does **not** use options
chain data, open interest, strike-level exposure, or any real dealer
positioning feed. It has no access to that data and makes no claim to. Every
input is ordinary OHLCV price/volume plus one standard, publicly-quoted
volatility index (VIX, VXN, or RVX depending on the chart's symbol) and the
US Dollar Index (DXY) — all pulled the same way any other indicator reads a
second symbol. "Pressure" here means *inferred* pressure from how price,
volume, and implied volatility are behaving, not a measurement of actual
options-dealer hedging flow. Treat it as a momentum/positioning-flavored
composite, not literal gamma exposure.
**How it's derived (in general terms)**
Six signals, each normalized to a -1..+1 range:
1. **Price momentum** — recent directional thrust, scaled by ATR so it reads
consistently across calm and volatile stretches.
2. **Volatility-index slope** — the rate of change in the symbol-appropriate
VIX-family index. Falling implied volatility is treated as a bullish
contribution (consistent with the common pattern of vol compressing as
markets grind higher), rising vol as bearish. This is the closest this
script gets to "options-flavored" input, and it's still just an index
level, not chain data.
3. **Volume flow** — session-cumulative volume, signed by whether each bar
closed above or below its open, with decay so recent bars dominate over
stale ones.
4. **Trend agreement** — two EMA lengths' slopes; when both agree in
direction and magnitude the reading strengthens, when they disagree it
pulls back toward neutral.
5. **Dollar Index pressure** — DXY's slope, sign-flipped, as a cross-asset
risk-on/risk-off cross-check.
6. **Candle conviction** — body-to-range ratio adjusted by relative volume,
i.e. how decisively the current bar closed, weighted by how much volume
backed it.
The six normalized signals are combined as a user-weighted average (every
weight is adjustable — nothing is hard-coded as "the right" calibration),
smoothed, and scaled to the final -100..+100 line. The main plot is a
histogram of the Pressure value; a second line plots its own slope (rate of
change), so you can see both the level and how fast it's building or fading
at a glance.
**Reading it**
- **Zero line** — the basic bias flip point. Above zero = net bullish
pressure by this composite's reckoning, below = net bearish.
- **±50** — a stronger, more sustained reading — most of the six components
are likely agreeing.
- **±80** — an extreme reading. Not an entry trigger by itself — treat it as
"pay attention," often either a continuation or an exhaustion point, and
confirm with your own structure/levels.
**Alerts included:** bullish/bearish zero-cross, strong bull/bear (±50
cross), and extreme bull/bear (beyond ±80).
**Symbol handling:** the script auto-detects which volatility index to
reference based on the chart's symbol (Nasdaq-family → VXN, S&P-family →
VIX, Russell-family → RVX), so it can be dropped on any of the supported
symbols without manual setup. It's built for liquid US equity-index
instruments specifically — the underlying logic (vol-index slope, DXY
cross-check) doesn't carry the same meaning on commodities, forex, or
single-name equities outside that set.
**Bottom line:** this is a transparent, fully-adjustable composite built from
public price, volume, and index data — not a real-time options-flow feed.
Use it as one more lens on directional pressure, not a substitute for actual
market structure or your own risk management.
