Volatility Rating

Volatility

Daily volatility rating combining 57 features. 1-2 = calm, 5-6 = average, 9-10 = extreme.

Scale

1-10

How to Read

Higher numbers mean wider ranges and more opportunity, but also more risk.

Every trading day. Size positions according to the number.

CRC (Curistat Regime Composite)

Volatility

Fuses 5 proprietary statistical models into one regime score.

Scale

0-100

How to Read

Score below 30 = low-vol regime. Above 70 = high-vol regime. Transitions matter most.

Calculation

Proprietary ensemble of 5 peer-reviewed statistical models spanning regime detection, order flow analysis, change-point detection, memory estimation, and complexity measurement.

When It Matters

Regime changes. A jump from 30 to 70 signals fundamentally different market behavior.

CTI (Curistat Tradeability Index)

Volatility

How tradeable today's conditions are. Factors volatility, regime clarity, and event density.

Scale

0-100

How to Read

Above 70 = great trading conditions. Below 30 = consider sitting out.

Calculation

Composite of rating stability, CRC clarity, event calendar density, and liquidity conditions.

When It Matters

Before placing trades. Below 30 = sit on hands.

CESI (Curistat Event Surprise Index)

Event

Measures how much today's economic releases deviated from consensus expectations.

Scale

0-100

How to Read

Near 0 = data matched expectations. Above 60 = significant surprise. Above 80 = major shock.

Calculation

Standardized deviation of actual vs consensus across all releases, weighted by historical impact.

When It Matters

After data releases. High CESI = expect range expansion.

LPI (Liquidity Pulse Index)

Market

Real-time liquidity conditions based on bid-ask spreads, depth, and volume patterns.

Scale

0-100

How to Read

Above 60 = healthy liquidity. Below 30 = thin markets, expect slippage.

Calculation

Composite of bid-ask spread z-score, order book depth, and volume relative to 20-day average.

When It Matters

During fast markets. Low LPI = wider stops needed.

Sentiment Composite

Direction

Aggregated sentiment from put/call ratios, VIX term structure, and positioning data.

Scale

-100 to +100

How to Read

Positive = bullish sentiment. Negative = bearish. Extremes often precede reversals.

Calculation

Weighted average of equity put/call ratio, VIX term structure slope, and CTA positioning estimates.

When It Matters

Extremes (<-70 or >70) often precede reversals.

VIX RSI(2)

Direction73% win rate

2-period RSI of VIX. Below 5 = VIX oversold (bearish for stocks). Above 95 = VIX overbought (bullish).

Scale

0-100

How to Read

Extreme low readings (below 5) warn of complacency. Extreme high readings (above 95) suggest fear is peaking.

Calculation

2-period Relative Strength Index applied to VIX closing values.

When It Matters

At extremes. VIX RSI(2) below 5 has preceded SPY pullbacks historically.

SPY RSI(2)

Direction71% win rate

2-period RSI of SPY. Below 10 = oversold bounce likely. Above 90 = overbought pullback likely.

Scale

0-100

How to Read

Below 10 = look for long entries. Above 90 = consider taking profits or hedging.

Calculation

2-period Relative Strength Index applied to SPY closing values.

When It Matters

Short-term mean reversion setups when RSI(2) hits extreme levels.

Connors CVR

Direction68% win rate

Modified Connors VIX Reversal signal combining VIX stretch and SPY mean reversion.

Scale

Bullish / Bearish / Neutral

How to Read

Bullish = VIX stretched high + SPY oversold. Bearish = opposite. Neutral = no signal.

Calculation

Combines VIX distance from its 10-day MA with SPY RSI(2) readings.

When It Matters

When VIX and SPY reach simultaneous extremes in opposite directions.

Consecutive Days

Direction65% win rate

Number of consecutive up or down days in SPY. 3+ in either direction increases reversal probability.

Scale

Count

How to Read

3+ consecutive down days = bullish edge next day. 3+ consecutive up days = mean reversion risk.

Calculation

Count of sequential closes above or below prior close.

When It Matters

After 3+ consecutive days in one direction. Reversal probability increases with streak length.

Turnaround Tuesday

Direction67% win rate

After a down Monday, Tuesday has a statistical bullish edge. One of the most robust calendar effects.

Scale

Active / Inactive

How to Read

Active = Monday closed down, so Tuesday has a bullish bias. Inactive = Monday was flat or up.

Calculation

Binary: checks if Monday's SPY close was below Friday's close.

When It Matters

Tuesday mornings after a red Monday. Size appropriately for a mean-reversion setup.

Turn-of-Month

Direction72% win rate

Last 2 and first 3 trading days of each month show persistent bullish bias from fund flows.

Scale

Active / Inactive

How to Read

Active = within the turn-of-month window. Expect a bullish tailwind from institutional flows.

Calculation

Calendar check: trading day -2 through +3 relative to month boundary.

When It Matters

Position sizing. The turn-of-month effect adds a few points of expected value on average.

IBS (Internal Bar Strength)

Direction66% win rate

Where price closed relative to its range: (Close-Low)/(High-Low). Below 0.2 = bullish next day.

Scale

0 to 1

How to Read

Below 0.2 = closed near the low, bullish reversal likely. Above 0.8 = closed near the high, bearish lean.

Calculation

(Close - Low) / (High - Low) for the daily bar.

When It Matters

End-of-day analysis. IBS below 0.2 is a simple but effective mean-reversion filter.

VIX Term Structure

Direction

VIX vs VIX3M ratio. Above 1.0 (backwardation) = stress. Below 0.85 = complacency.

Scale

Contango / Backwardation

How to Read

Contango (VIX < VIX3M) is normal. Backwardation (VIX > VIX3M) signals fear and hedging demand.

Calculation

VIX / VIX3M ratio, evaluated daily.

When It Matters

Regime identification. Persistent backwardation = crisis mode. Deep contango = low-vol regime.

Overnight Gap Fill

Direction

Probability that today's gap from yesterday's close gets filled during RTH.

Scale

Probability %

How to Read

Higher probability = gap likely fills. Small gaps (< 0.3%) fill more reliably than large gaps.

Calculation

Historical fill rate stratified by gap size, direction, and day-of-week.

When It Matters

Opening range trades. Small gaps fill more reliably than large ones.

ETH Range

Volatility

Expected range for the overnight (ETH) session. Usually 40-60% of RTH range.

Scale

Points

How to Read

Compare to actual ETH range to gauge whether overnight was quiet or active relative to expectations.

Calculation

Rating-adjusted historical ETH range distribution for the predicted volatility bucket.

When It Matters

Overnight position sizing. Wider expected ETH range = wider stops needed.

ETH S/R (Support/Resistance)

Market

Key support and resistance levels established during the overnight session.

Scale

Price levels

How to Read

These levels often act as magnets or barriers during the first 30-60 minutes of RTH.

Calculation

High, low, VWAP, and volume-based POC from the ETH session.

When It Matters

RTH open. ETH levels often act as magnets or barriers.

Expected Range

Volatility

Predicted high-to-low range for the session, based on the volatility rating and historical bucket stats.

Scale

Points

How to Read

Use as a guide for profit targets and stop distances. A Rating 7 day has a much wider range than Rating 3.

Calculation

Median and percentile ranges from historical sessions matching the predicted rating bucket.

When It Matters

Every session. Sets your profit targets and stop distances.

Session Type Buckets

Volatility

Sessions classified into 5 volatility buckets (Very Low, Low, Average, High, Extreme) with distinct range statistics.

Scale

5 types

How to Read

Each bucket has its own median range, standard deviation, and tail behavior. Match your strategy to the bucket.

Calculation

K-means clustering on historical session range distributions, mapped to volatility ratings.

When It Matters

Understanding what a rating of 7 actually means in point terms.

ES/NQ Divergence

Market

Standardized spread between ES and NQ returns. Extreme z-scores (>2 or <-2) suggest mean reversion.

Scale

z-score

How to Read

z-score > 2 = NQ outperforming ES by an unusual amount, expect convergence. < -2 = opposite.

Calculation

Rolling z-score of daily ES return minus NQ return over a 20-day window.

When It Matters

Pairs/spread trades. Divergence >2 std dev reverts within 3 days 78% of the time.

Value Area / POC

Market

Volume Profile: Point of Control (highest volume price) and Value Area (70% of volume). Key support/resistance.

Scale

Price level

How to Read

Price above Value Area = bullish. Below = bearish. POC acts as a magnet.

Calculation

Volume profile analysis: POC = price with most volume. VA = 70% of total volume centered on POC.

When It Matters

Identifying fair value. Price outside Value Area tends to return to it.

CTA Positioning

Direction

Estimated systematic CTA position in ES based on trend-following model replication.

Scale

Long / Short / Flat

How to Read

Max Long = vulnerable to forced selling on any downturn. Max Short = short squeeze risk on rallies.

Calculation

Replication of typical CTA trend-following models using moving average crossovers on ES.

When It Matters

When CTAs are max long, forced selling on any downturn can move ES 40-60 points.
