Where
all the DLLs in this Equis forum you refer to? I've registered but can't
find any DLLs
though
forum FAQ says DLLs available in the forum but doesn't say where they
are.
Thanks,
Vladimir

[EquisMetaStock Group] Dynamic Momentum Index (DMI)
An indicator I think you will
enjoy.
Preston
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.
