I
agree 100% with your findings. Frankly, that is why I've made the
switch to AmiBroker and will never look back.

[EquisMetaStock Group] Bugs in v8.01I have been
working with the Equis Technical Support personnel since I purchased v7.0
in June of 2000. The support has been excellent, so when v8.0 was
released, I bought it. I had developed my own trading algorithm and
was particularly interested in being able to calibrate it against a
portfolio of equities with the System Tester. However, I found the
number of bugs in v8.0 was overwhelming and I had to revert back to using
the v7.22 System Tester. My personal observation was that version 8.0 was
not even qualified for alpha testing at the time of its release. I
was delighted when v8.01 was released six months later. I thought
the bugs had been corrected. I was wrong. I discovered that
v8.01, although a big improvement, would barely qualify as a beta test
version. I was both upset and embarrassed because I had talked two
friends into buying v8.01.With both v7.22 and v8.01 on the same
computer it is easy to compare System Tester results. The results
between the two versions running the identical algorithm are drastically
different, regardless of whether they are being run in normal or
points-only mode. This occurs when v8.01 has been carefully configured to
reproduce v7.22 results. Bottom line is that v7.22 results make sense,
v8.01 results do not. Technical support has not been able to explain
the differences, nor provide a workable solution. I still do not use
v8.01. I use only v7.22 because it is the only version that I
trust.What I find unusual is that I can't find any other reference on
the internet to the mismatch between v7.22 and v8.01 System Tester
results. In my 43 years of using computers for problem solving, and
having written, debugged, and documented roughly 100,000 lines of
code, one of the primary requirements when modifying programs is that
they must be able to correctly reproduce previously validated
results. This test was obviously not applied to v8.0 or v8.01.
Yet it is the only way to validate the changes made to the
program.Is there anyone out there that encountered this situation and
understands its significance?DavidTo
