Dynamic Momentum Index (DMI)
Description:
The Dynamic Momentum Index (DMI) was developed by Tushar Chande and
Stanley Kroll. The indicator is covered in detail in their book The
New Technical Trader.
The DMI is identical to Welles Wilder's Relative Strength Index
except the number of periods is variable rather than fixed. The
variability of the time periods used in the DMI is controlled by the
recent volatility of prices. The more volatile the prices, the more
sensitive the DMI is to price changes. In other words, the DMI will
use more time periods during quiet markets, and less during active
markets. The time periods the DMI can reach is around a maximum of 30
and a minimum of 3. The volatility index used in controlling the time
periods in the DMI is based on a calculation using a five period
standard deviation and a ten period average of the standard
deviation. The advantage of using a variable length time period when
calculating the RSI is that it overcomes the negative effects of
smoothing, which often obscure short-term moves.
In this indicator the option to use a bipolar index is also
introduced. The formula for a bipolar index is Bipolar =( up -
down ) / ( up + down )
Interpretation:
Chande recommends using the DMI much the same as the RSI. However,
because the DMI is more sensitive to market dynamics, it often leads
the RSI into overbought / oversold territories by one or two days.
Like the RSI, look for overbought (bearish) conditions above 70 and
oversold (bullish) conditions below 30. However, before basing any
trade off of strict overbought/oversold levels using DMI or any
overbought/oversold indicator, Chande recommends that you first
qualify the trendiness of the market using indicators such as r-
squared or CMO. If these indicators suggest a non-trending market,
then trades based on strict overbought/oversold levels should produce
the best results. If a trending market is suggested, you can use the
DMI to enter trades in the direction of the trend.

I just purchase a metastock . so I really dont know anything. I try
to spend some quality time right now to understand the language
arrangement a part of my post grade study.
