Adaptive Volatility Analysis - MetaTrader 4 Script | Forex Indicator Download - MT4/MT5 Resources

The AVA (Adaptive Volatility Analysis) indicator is a tool I developed primarily to enhance my own indicators and Expert Advisors. It is designed to measure market price movements more accurately. Unlike standard indicators that provide a static view of the market, AVA adapts its analysis based on current market dynamics. This adaptability makes it valuable for predicting transitions to higher volatility or calmer periods. This indicator is mainly designed for use by genetic algorithms.

How it works:

Start with ATR : The basis of the AVA indicator is Average True Range (ATR), which quantifies market movement over a certain number of past trades (usually 14 trades by default).

Smoothing with EMA : This indicator uses two exponential moving averages (EMA) applied to the ATR value - short-term EMA (default is 2) and long-term EMA (default is 5). For long-term analysis, we can choose longer periods such as 10 and 50. These EMAs help smooth out the ATR readings, making it easier to identify price movement trends.

FAV Ratio : The core of the AVA indicator is the FAV (Adaptive Volatility Factor), which is calculated by dividing the short-term EMA of the ATR value by the long-term EMA. This ratio adjusts the indicator's sensitivity to market changes, ensuring it remains sensitive to both subtle and major changes.

Determining the AVA Value : The final AVA value is determined by modifying the FAV ratio: FAV minus 1, then multiplied by 100. This will give you a percentage that represents the current level of market volatility.

Exact calculation:

Favorites = EMA_short (Attenuated Total Reflection) / EMA_long (ATR)

User Guide:

Explaining the Indicator : The AVA indicator appears on a separate chart below the main trading chart. Increasing AVA values ​​indicate increased market volatility, while decreasing values ​​indicate lower volatility or reduced stability.
