variable index dynamic average (VIDYA) developed by Tushar Chande by default is contained in MT5 but not in MT4
platform and it is a dynamic EMA (Exponential Moving Average) that adjusts its Length (LB Period) automatically in response to Market
Volatility originally measured through the Chande Momentum Oscillator(CMO).
CMO value is used as the ratio to the smoothing factor of EMA (The New Technical Trader by Tushar Chande and
Stanley Kroll, John Wiley and Sons, New York, 1994).
The higher the volatility, the higher the emphasis on price becomes and the faster VIDYA adapts to price changes and so VIDYA generally remains
closer to prices than the equivalent common EMA. Hence its responsivness can give us more timely trades, which is
the main advantage of using VIDYA.
VIDYA can be used as any moving average, to identify and trade trends.Traders often use its upper and lower borders (bands), that are by N % above
and below the VIDYA line and generally in combination with other signals and analysis techniques.
Note
Although originally CMO is used as a measure of Market Volatility for calculating VIDYA we could also use for this any other suitable Market
variable like standard deviation of closing prices, the coefficient of determination (r^2) or another momentum oscillator
etc.
