I was
reading the exchange you were having with Freddie and decided to take a look at
this also.

I have
eSignal data and it does show data for TAG on 5/8/03. Thus, I created a
new security in the downloader called "Test TAG" and deleted the entire row of
data for 5/8 and saved it. I then used the Security function to plot the
close of "Test TAG" for the last 20 days on a chart of IBM. Interestingly,
it plotted the close from 5/7 again on 5/8 (I would have thought it would
have been blank).

function to generate trading signals. That is not the case. You can
use the Security function to reference the O,H,L,C,V and even embed it in
formulas. Thus, if you wanted to get a buy signal on IBM when the SPY
crossed it's 50 period SMA, that could be done very easily. This is true
whether you reference it in an Expert, Security Indicator,
System Tester or the Explorer.

[Metastockusers] Re: Question on Security functionHi
Freddie,Once again, thanks for looking into this.I have MS 7.2 EOD
which doesn't have the Security function built in but I do have the MS Dev
Kit so I can write most things.I'm very interested in intermarket
analysis and want to carry out some tests incorporating other
markets. The Security function makes this easy. E.g. if Bonds down,
go long stocks (that sort of thing).I don't see any reason why you would
not be able to incorporate the Security function to generate trade signals
with the Metastock system tester.I wrote my own version of a
'Security' function and just happened to test it on TAG which showed up
this issue.Any chance you could try this?1. Open TAG chart (just
last 20 periods).2. Confirm there is no data for 5/8/2003 (YAHOO doesn't
have any).3. Open IBM chart (again - just 20 periods).4. Add an
indicator to the IBM chart which is basically a call to the Security
function to retrieve the closing price of TAG.5. Does this indicator
display something for the whole 20 periods? If so, what does it
generate for 5/8/2003 when there is nothing for it to return? This
is the key question.Once again, many thanks for your
help.Sean
