Hello,
While we are at giving credits, if you deny giving Howard
a credit for influencing AmiBroker for mere fact that he did not "invent"
Walk-Forward, for sake of correctness
you would probably need to mention original authors of
ideas, not only the followers.
The Walk-forward testing of systems was pioneered
by Robert Pardo in **1991**
PSO by James Kennedy and Russel C.
Eberhart in 1995
And portfolio backtesting first appeared in Trading
Recipes in 1994
And for your information without Howard you would not see
walk-forward in AmiBroker in current shape. Why? Because
he was among people who
a) asked for it and popularized it in his
book
b) tested early versions
c) provided feedback that helped to make it as user
friendly as it is now.
Best regards,
Tomasz Janeczko

Where Can You Find Customer Service Like TJ Provides?
You said, " Howard Bandy's published analytical approaches using
AB as a platform
have resulted in new AB functionality that TJ has
incorporated into
the product." . Which functionality is this? If
you're thinking about objective function and Walk forward analysis, that
was pioneered by Fred ages ago. Otherwise, my mind is blank. Please
enlighten.
TJ's business model is certainly unique.
NEVER before have I
seen a business owner / developer directly
involved with each and
every customer thru a forum like this.
TJ deserves praise for
tightly integrating increasingly sophisticated
functionality into the
AB product.
But the AB customer community deserve a great deal of
praise for
innovative ideas that TJ ultimately adapted to
AB.
Fred is a free-thinker who introduced us to the concepts of
portfolio
backtesting and PSO which have since been tightly
integrated into AB.
William Peters introduced the 'wizard'
concept for non-programmer's
which has since been improved upon
and tightly integrated into AB by TJ.
Howard Bandy's published
analytical approaches using AB as a platform
have resulted in new AB
functionality that TJ has incorporated into
the product.
And
there are quite a few other users whose ideas / suggestions TJ
has
implemented into the AB product. And of course Dimitris was
the
ultimate 'end-user' in years past who could show us all how
to
implement new features of AB.
None of this takes away from
TJ's development skills, but it is
important to acknowledge the
contributions of the entire AB community
in the evolution of
AB.
