il RAVI !! mooolto più semplice da calcolare ... no frills, semplice anche da capire
RAVI Indicator (RAVI)
Description
Tushar Chande published the RAVI indicator (Rapid Adaptive Variance Indicator) in his book "Beyond Technical Analysis" in 1997. Like the ADX, the RAVI indicator differentiates between a trending market and a trading market. Although the RAVI measures the trend intensity, it does not distinguish which way the trend is going. As a result: a rising RAVI shows the beginning of a trend or an increase in trend intensity, but not the trend direction. Similarly, a falling RAVI shows the end of a trend or a decrease in trend intensity, but not the trend direction itself. A distinction between these two indicators that is worth mentioning is that the RAVI indicator often reacts more quickly and exhibits a more pronounced curve than the ADX.
Calculation
First of all, the 65 MA is subtracted from the 7 MA, and this difference is divided by the 65 MA. The quotient is multiplied by 100. In order that a positive result is always attained, the absolute value of the product is formed.
Formula
RAVI(t) = VIDYA(x) – VIDYA(y)
VIDYA(x) = Variable – Index – Dynamic – Average shorter Period
VIDYA(y) = Variable – Index – Dynamic – Average longer Period
Parameters
The adjustable period length for both MAs can be chosen from 1 to 500. For the most common setting of the period length, Tushar Chande suggested that the shorter MA be 10 % of the longer MA.
Interpretation
The higher the RAVI, the greater the trend intensity and the stronger the underlying trend.
Note: As long as the RAVI is rising, oscillators should not be used. The RAVI can be used as a filter between oscillators and trend-following indicators.
