3 "constants" that inidicate what type of' back test is to be run. Below

cstPortFolioBackTest"' line to relect the type of backtest you want to
run:' BackTestType = cstPortFolioBackTest' BackTestType =

VBScript to automate back test and export of tradelist.
<SPAN
class=734061511-20042004>Very nice d, thanks for creating this code, it
works like a charm!
<SPAN
class=734061511-20042004>
A
few questions,
1)
Is the portfolio BT mode available in Automation and if so, can your code be
adapted to do Port BTs?
<SPAN
class=734061511-20042004>2) I would I add a few command line arguments to
your code so that, for example, I can change the systems code, dates,
etc. without editing,
possible?
3)
What happens if I specify a future date for the "To:" data... would AB
default to the last available data bar?
<SPAN
class=734061511-20042004>
<SPAN
class=734061511-20042004>For those who haven't followed this topic, the
purpose of this export is to be able to use BT stats (CAR, RAR,
K-Ratio, etc.) in 2-nd pass BTs. The csv file can be read using file
operations code documented in the Help. Once the first export has been
completed you can then extract any stat you like with StrExtract() for
use in subsequent BTs.
