RE: [Metastockusers] Re: Question on Security function

[Freddie Ng <n07476@xxxxxxxxxxxxxx>]

Joe,
Thanks for participating in this experiment. You seems to be very
conversant in metastock programming. Are you able to demonstrate the use
of the security function to generate a trade signal. I am trying but
getting nowhere. The chart plotted by the security cannot be used with
the expert advisor, system tester or the explorer. Whenever I use the
expert adviser, it defaults to comments only on the parent security
rather than the security plotted by the security function. 
Best Regards
Freddie Ng

Sean,
 
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). 

 
Freddie seemed to be
suggesting that you can not use the Security() 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.  
 
Good
Trading,

function

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.

Sean
