I keep forgetting to post a note about an explorer bug I notice a
while back while experimneting with some historical tests.
When you run an exploration, if has a filter it rejects some of the
stocks you run through it. That's normal. There is also a normal group
of reasons for rejection and the filter is only one. Ocasionally
you'll get a rejection for a reason associated with MS's ability to
get the data.
However, if you run the same exploration multiple times over a range
of dates, you may get a lot of rejections for
Maximum number of securities alrealy locked.
Sometimes the rejection rate can be as high as 70%.
THIS IS NOT THE ERROR WHICH IS FIXED BY INCREASING THE FILE LOCKS IN
THE REGISTRY TO AN AMOUNT above 250,000. That's a completely different
issue.
Equis knows about the problem and said that in the last version of MS
they noticed it during testing but it didn't happen too often so they
didn't fix it.
The only way to stop the error is to shutdown MS and start it up
again. That's a pain when you have to run a number of historical
explorations for system testing.
A lot of people have the problem but they don't notice it because very
few people open the rejects tab, and very few people run multiple
explorations across more than the current date.
This is a major problem. All of you should make sure that when you run
an exploration you know why you're getting rejects.
If you see this problem, report it to Equis so they can finally figure
out it's not minor and they need to fix it.
Even when they figure it out, given they're track record they won't
bother to fix it because it doesn't interfere with them selling new
copies of MS to unsuspecting people. That's sad, but it's the truth
Anyway watchout for this error. It can change your results dramatically.
