VIX technical analysis: interpret volatility without predicting a bottom

What a reading of 20 means

A VIX reading of 20 expresses 20% annualized implied volatility. A simple square-root-of-time conversion gives 20% × √(30 / 365) ≈ 5.73% over 30 calendar days. At an invented index level of 5,000, that is approximately 287 points of scale. It is not a forecast that the index will move up or down by that amount.

• This conversion is a rough constant-volatility scaling illustration. It is not an exact probability interval, a maximum move or a complete option-implied distribution.
• Do not mix a 365-calendar-day convention with a 252-trading-day realized-volatility calculation without explaining the difference.
• The index aggregates option information. It does not identify which participants bought protection or prove their motives.

Use thresholds as labels, not universal regimes

Levels such as 13, 20 and 30 can be chosen to segment a study. They are not Cboe-defined thresholds that make options cheap, prescribe a position size or prove that a crisis has peaked.

Distinguish a futures curve from the spot-to-futures gap

Record exact futures expirations and use observations from the same time. A farther-dated future above a nearer-dated future is an upward slope for that pair, commonly called contango; the reverse is backwardation. A comparison between spot VIX and only one future does not describe the entire curve.

• Invented example: spot VIX 25, first future 22 and second future 24. Spot exceeds the first future, while the two-future segment slopes upward. Those are compatible observations.
• A future’s price reflects exposure associated with its future settlement date. It need not track spot point for point.
• A fund that rolls futures has its own methodology, fees and potentially leverage or inverse exposure. A spot-index chart is not its return history. Read the instrument’s documents before substituting one for the other.

A Pine display that requests the VIX symbol explicitly

This indicator requests the selected volatility-index symbol at the chart interval and draws editable reference lines. It is descriptive: it does not mark exhaustion, send alerts or simulate trades. The reference defaults are illustrative, not fitted regime boundaries.

• Use standard charts. The result follows the selected data feed and the chart’s available timestamps; it is not an independent record of every VIX observation.
• An invalid or unavailable symbol produces missing values rather than substituting the chart’s own close. Gaps are left visible.
• Developing requested bars can change until confirmed. lookahead_off avoids a future-looking merge but does not make every live value final.

Test a claim about spike reversals separately

Before viewing outcomes, define the threshold, lookback, crossing event, observation time and equity instrument to evaluate. Record every eligible event, overlapping signals and transaction assumptions. Compare with a baseline and a separate evaluation period.

• Long upper wicks in a volatility index do not automatically mark the exact low of another instrument. Specify both event and outcome windows.
• A tendency to move back toward historical levels does not fix the timing, path or next regime. VIX is not bounded between 0 and 100 like RSI.
• This page provides no measured success rate or profitable VIX strategy. A chart screenshot cannot supply a complete event sample.
