Betreff: Re: Replacement for TS with EOD in mind
Ok, I cannot resist replying to this one :-)
You are describing PowerST!

Yes, except there is not native walk forward optimization. However, a
current customer has been accomplishing this type of testing with some
external programming and Macro Express.

Sharpe, yes. Ulcer Index, no. However, all performance statistics are
end
user programmable. End users can add any performance statistics they
desire
(and even add them to the standard reports), and this is a feature which
current customers are taking advantage of.

Yes! This is one of the strong points of PowerST.

Commission and slippage can be expressed as a percent.

10 data series for 50 years is absolutely no problem. However, I would
want
to discuss exactly what kind of testing you need to accomplish because
this
request is general and I wouldn't want to make misstatements.

Yes!

Yes. There is a built in editor, but some PowerST users prefer to use
their
favorite text editor instead.

You download data files with the data vendor software. Then import is
automatic.

Yes

Definitely yes.

You can call DLLs, but the language is powerful and fast so there is no
need for calling DLLs for power or performance reasons.

In historical testing, or for tracking forward trading? Yes, for
tracking
forward trading. For historical testing, let's talk about it. I am
thinking
that the short term yield can be faked as a trade during the flat
periods.

PowerST is lean and mean :-)

PowerST is the best around for EOD. There is currently a small community
of
early adopter customers using PowerST intensively as their primary
testing
software. These are people who have done the full evaluation of
alternatives, and ended up with PowerST.
>Barry.
For those who have been following the discussion about PowerST, I got a
lot
of criticism about the original $5000 price. As a result, I have bowed
into
pressure and reduced the price to $2500 for individual traders (the
price
is still $5000 for trading businesses with up to $10 million under
management) Here is a quote from an email I sent to a customer recently:
<<<<
I am still 50/50 about the decision to reduce the price from $5000. Or
maybe I should say I am decisively 51/49 - I am very likely going to
stick
with the $2500, at least through the introduction period.
>>>>
I just uploaded a web site update. Charting is now working, and the
PowerST
charts are very nice.
Take a look!
