Description
The Dynamic Momentum Index study is quite similar to Welles Wilder's Relative Strength Index. The difference is that DYMI uses variable time periods (from 3 to 30), whereas RSI uses fixed ones.
The variability of the time periods used in the DYMI is controlled by recent volatility of prices. The more volatile prices suggest the more sensitive DYMI towards price changes. During quiet market conditions, DYMI uses more time periods than when more active markets occur. As a result, the DYMI is more sensitive to fluctuations in the market and displays changes more rapidly than the RSI can.
