<DIV><FONT size=2>> One weakness of this method is that the indicator which
uses the inner window<BR>> data as its base security cannot be selected or
edited. This means you have<BR>> to delete the inner window contents

<DIV><FONT size=2><FONT size=2>
<DIV><FONT size=2>The formula for calculating the RSI is:
<BR>rsi=100-(100/(1+rs))</FONT></DIV>
<DIV><FONT size=2>where:</DIV></FONT>
<DIV><FONT size=2>rs = average of x day’s up closes divided by average of x
day’s down closes</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Or, as can also be read in the MS65-man (p. 488)
:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>The RSI is a fairly simple formula, but is difficult to
explain without pages of examples.</FONT> </DIV>
<DIV><FONT size=2>The basic formula is:</FONT></DIV>
<DIV><FONT size=2><BR>RSI=100-(100/(1+(U/D)))<BR></FONT></DIV>
<DIV><FONT size=2>Where:<BR>U = An average of upward price change.
<BR>D = An average of downward price change. <BR>MetaStock prompts you
to enter the number of time periods in the averages.</FONT></DIV>

<DIV><FONT size=2>This Custom RSI-formula printed below, too can be found on
Equis' Website, but now on page</FONT></DIV>

<DIV>Equis' Bill Forman suggested its use, and was accompanied by a brief
explanation, in an email</DIV>
<DIV>(Dated 19981102 - Subject: RE: Relative Strength Index) and as such his
mail contained some</DIV>
<DIV>more additional info to what is already been printed on the -below-
webpage itself.</DIV>
<DIV> </DIV>
<DIV>From eye-balling couldn't notice a difference between the on the
"cf00075.html" page printed</DIV>
<DIV>formula and the on the "cf00098.html" printed formula (as suggested by
Nicholas), but noticed</DIV>
<DIV>that the 75-version was parsed a little bit better and therefore easier to
read (when working on</DIV>
<DIV>your own version, eg to do some changes).</DIV>
<DIV>Applying other indicators for underlying values, naturaly, will force you
to do some work especially</DIV>
<DIV>to the "B:" function AND the further in "Z:" + "Y:" used underlays (eg
here the O,H,L,C,V will have</DIV>
<DIV>to be replaced by f.i. a H-L range or just another indicator type like
MACD() or etc. ................).</DIV>
<DIV>Note that the (by me added) at the end used "RSIV:" is an adjustment that
is only "opticaly" required</DIV>
<DIV>here, for in the way that this formula source code is here written, it is
not a straight RSI</DIV>
<DIV>< but it is now written for an > "Relative Strength Volume
Index"-indicator.</DIV>

<DIV><FONT size=2><FONT size=2>Wilder uses his own form of "exponential"
smoothing in his RSI. That is<BR>why the function "Wilders Smoothing" was
added to version 6.5 of<BR>MetaStock for Windows 95 & NT. Basically,
on day 15 and all subsequent<BR>days, Wilder takes the previous average up close
and multiplies it by<BR>13, add today's up close (if any) and divides that value
by 14. He does<BR>the same with the average Down close. You then
divide the ups by the<BR>downs, add 1.00 to it and divide that into 100 and then
subtract that<BR>result from 100. You have the RSI. Note how he uses
a value multiplied<BR>by 13 and divides by 14 for a 14 time period
RSI.<BR><BR>To match this in a custom formula, you must use the "Wilders
Smoothing"<BR>function.<BR><BR>Here is a custom formula to use other than the
close in the calculation.<BR>It is posted on our web page.<BR><BR>Equis
