Re: MS explorer

Hi Bill,

I use quotemonster. It's free and works allright. I only download once a week on
saturday and this works fine.

In this specific case I removed the last day data manually for one security to
see how MetaStock would rank.
I think that regardless of my data-acquiring program MetaStock should not (at
least I find this odd) report on
data that are not there (or replace it without notice with yesterday's data, I
could not find anything in the MS
manual that mentions this feature)

I'm backtesting (matlab) a system based on ranking conditions. (several years
back). This kind of system is
practically impossible in MS because of the many 'target dates' you have to set.
So, if you have no close value
on a specific date for a particular security because of some reason, you don't
have a result for that specific date.
Hence, it may not appear in your ranking list, at least as far as I can see it.
So the manual deletion of the last day date was a simulation of something you
might encounter when backtesting
ranking systems several years back.

Hope this clarifies ...
Leo

 Leo:

What program are you using to obtain Yahoo data?   Some programs automatically
obtain delayed (Reuters), rather than historical  (CSI), data and then overwrite
the delayed when the historical is  available.  It sounds like your program
automatically fills in the current  date with the last available historical
data, which could be confusing.   Have you looked at the raw data to see what
the program is  doing?

Hi,

When using the explorer to rank securities according  to a specific RSI value, I
'discovered' something strange.

Say  you're screening for an oversold condition on the most recent date (or
specific date if you want to do some
backtesting) and one of your  securities lacks to most recent data (or some
historical value if you're  backtesting)
it still shows up in the report and can be even your best  candidate !! For this
security the yesterday's value is
used!

Is  this normal ? Known ?

I use Yahoo (CSI) for data  retrieval.
