The VIX Index, or CBOE Volatility Index, is an indicator designed for MetaTrader 5 that transforms historical volatility into an easy-to-interpret oscillator, placing the volatility range between 0 (minimum) and 100 (maximum) based on a configurable normalization period.
Unlike a simple ATR, this oscillator shows you on the chart when volatility is abnormally low or high compared to its recent behavior. Additionally, the indicator provides context and information about the famous VIX Volatility Index, known as the “fear gauge” in financial markets.
What is the VIX Index?
The VIX (Chicago Board Options Exchange Volatility Index) measures the 30-day implied volatility of S&P 500 options, reflecting investors’ expectations of the magnitude of market movements.
It was launched in January 1993 as a real-time calculation based on at-the-money S&P 100 (OEX) option prices, and was later adapted to the S&P 500. Each day, the VIX is calculated from standard and weekly option quotes, using a filtering algorithm to discard unrepresentative data.
In 2016, its publication was extended to cover hours outside the regular Wall Street schedule, enhancing its global usefulness.
How is the VIX calculated?
The VIX calculation weighs the premiums of call and put options on the S&P 500 with different expirations, interpolating the implied volatility of two option series to obtain the 30-day volatility expectation.
It considers the ratio between out-of-the-money puts and calls, thus measuring the relative demand for protection versus speculation.
Level Interpretation
-
Low VIX (<20): Indicates market complacency, tight trading ranges, and low uncertainty.
-
Medium VIX (20–30): Neutral or moderate level, typical volatility.
-
High VIX (>30): Indicates fear or panic in the market, wide movements, and potential contrarian opportunities.

How to use?

It can be easily found by searching in the MetaTrader symbols window, to improve the search type 500 in the search engine.Support & Contact
