Hi 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.
