<DIV>First, a large number is chosen, e.g. 20,000. Each day thereafter, the 
difference between the number of advancing issues and</DIV>
<DT>
<DIV>declining issues is added or subtracted, eg e<FONT size=2>ach day's number 
of declining issues is subtracted from the number of advancing</FONT></DIV>
<DT>
<DIV><FONT size=2>issues which results in the net difference. This net 
difference is then added to a running sum if the difference is positive 
or</FONT></DIV>
<DT>
<DIV><FONT size=2>subtracted from the running sum if the difference is 
negative.&nbsp;</FONT> Usually, New York Stock Exchange data is used for the

<DT><FONT size=2>The problem with the advance decline line is that it can be

<DT><FONT size=2>For example, by plotting a 20-day CMO or 14-day RSI&nbsp;based

<P><FONT size=2>There is a way to get the negative volume on an advance-decline 
line chart in MetaStock&#8482; for Windows&#8482;.<BR></FONT>
<P><FONT size=2>The requirement is: Each security must have both the number of 
issues and the volume in the file. Advancing issues with advancing volume in one 
security and declining issues with declining volume in one security file. These 
files may be obtained from Reuters Trend Data by way of The DownLoader for 
Windows. You will also need to create a composite security of the 
Advance-Decline line, which is the advances - declines.<BR></FONT>
<P><FONT size=2>The following steps will get you an advance-decline line with 
negative volume where applicable. Follow these steps once and save as a CHART. 
When you want to use it simply load the chart and the program will calculate the 
new volume plot using the new data.<BR></FONT>

<P><FONT size=5>Arms Index (TRIN )</FONT> 
<P><FONT size=1>rev. 01/06/97<BR></FONT>
<P>The Arms Index, also known as TRIN, is a market indicator that shows the 
relationship between the number of stocks that increase or decrease in price 
(advancing/declining issues) and the volume associated with stocks that increase 
or decrease in price (advancing/declining volume). The Arms Index was developed 
by Richard W. Arms, Jr. in 1967.<BR>
<P>The Arms Index is primarily a short term trading tool. The Index shows 
whether volume is flowing into advancing or declining stocks. If more volume is 
associated with advancing stocks than declining stocks, the Arms Index will be 
less than 1.0; if more volume is associated with declining stocks, the Index 
will be greater than 1.0.<BR><BR>
<P>The formula for the Arms Index is:<BR><BR>(Advancing Issues / Declining 
Issues) / (Advancing Volume / Declining Volume)<BR><BR>
<P>To calculate the Arms Index in MetaStock&#8482; for Windows you will need to first 
collect the four pieces of data.<BR>
<UL>
  <LI>Reuters Trend Data (RTD) supplies this data in two files. The tickers are 
  X.NYSE-A (Advances, number and volume) and X.NYSE-D (Declines, number and 
  volume). <BR>
  <LI>Dial/Data also supplies this data in two files. Advances, number and 
  volume and Declines, number and volume. The tickers are @*NAZ_K and @*NDZ_K. 
  <BR>
  <LI>CompuServe supplies this data in 4 files. The tickers are NYSEI 
  (Advances)use the cusip 00000157 rather than the symbol; NYSEJ (declines); 
  NYUP (Advance volume) and NYDN (decline volume). <BR></LI></UL>
<P>After the data has been collected follow these steps:<BR>
<P>For data from RTD or Dial Data 
<UL>
  <LI>In the DownLoader&#8482; create a composite security of the Advances / Declines. 

  <LI>In MetaStock open the composite. 
  <LI>Create and plot the custom formula: C/V </LI></UL>
<DIV>This gives you the Arms Index (TRIN). <BR><BR></DIV>
<P>For data from CompuServe 
<UL>
  <LI>In the DownLoader create the two composites. 
  <UL>
    <LI>Advancing Issues / Declining Issues 
    <LI>Advancing Volume / Declining Volume </LI></UL>
  <LI>In MetaStock open both composites. 
  <LI>Tile the charts so they can both be viewed. 
  <LI>Drag the plot of the Adv. Volume/Dec. Volume composite into an inner 
  window in the Adv. Issues/Dec. Issues chart. 
  <LI>Create the custom formula: C/P 
  <LI>Plot this formula on top of the Adv. Volume/Dec. Volume plot (the Adv. 
  Volume/Dec. Volume plot will turn a purplish color to signify the formula will 
  be plotted on it). </LI></UL>
<P>You will know have the Arms Index (TRIN) plotted. You can drag it to its own 
inner window if you prefer.<BR>
<P>For interpretation refer to Mr. Arms book, <I>The Arms Index</I>.

Very interesting comments. Sounds like good advice. Apparently the voice of
experience.

One possible addition might be the Gann type of claim that there exists
"natural" support/resistance at 25 and to a lesser extent, 23 1/2 - 7/16
etc. as minor 1/8 points.
