Hello,
1. Even if it works it is completely not supported
and may to problems/crashes etc. It is like driving all the time on
reverse gear.
Reverse gear is not designed to be used for 10
hours drive.
2. I see no reason to "plot" single numbers like
UPI, number of trades in indicator. That would be just a bunch of flat
lines.
Also indicator should be lightweight. The indicator
code should execute very quickly because indicators are refreshed very
often.
You are (ab)using indicators for things not
designed for them. Indicator code is for indicators. Automatic analysis is for
backtesting. Indicators are not
and should never be used that way.
3. If you really need to plot them
- all stats are accessible from CUSTOM
BACKTESTER, if you want to "plot" them, use custom backtester,
write them to TEXT File (using fopen/fputs/fclose)
and from the indicator you will be able to read them (using
fopen/fgets/fclose)
That's a proper way to do that.
To repeat the same analogy - although you can drive
on reverse gear for 100 miles, your cars is not designed to be used that
way.
Best regards,
Tomasz

OK Tomasz, but the code produces a nice BT report each time i click the
Trigger. Seemingly flawless. Seems only a tweak would be required to make it
work robust.
I am going through all this trouble just to be able to access the
Backtester stats from an indicator (I was going to extract the last value from
the report on bar-by-bar BTs!).
System analysis in the time domain is frustrated/impossible because basic
AB users (non professional programmer) can't retrieve and plot the Backtester
stats, like UPI, %Winners, Number of trades, etc. Thus there is a big void wrt
system analysis - see my suggestion #1335 and support tag [#49377].
I wish that formulas for these functions were made public so that they can
be used in indicators. This Would open up a whole new world to evaluate,
analyze, and design trading systems. The single numbers in the AA give very
limited information. With all respect, please do not mention the CBT... that
solution is for less than 10% of users and I don't have enough days left to
learn all that stuff.
best regards,
herman

But... the example in help
a) works
b) presents OUTSIDE ***JScript*** code
http://www.amibroker.com/guide/objects.html
c) does not contain
AA.Analysis.RangeN (wrong line)
Again I want to stress that out that Analysis COM
object must not be used form
AFL level. The functionality is provided to control
Automatic Analysis from OUTSIDE
of AmiBroker.

won't do. Actually 99% of this code was copied from
the AB help.

Maybe AB won't let you run a backtest
within an indicator - time to ask TJ.

On the lines that give the error
substitute a number constant for the variable and see
if it works. If it does then it looks to me like it
thinks the variables are arrays.

OLE code?
Can someone help me fix the code
below so that when triggered in an Indicator,
it:
1) Backtest all tickers in
watchlist WLN?
2) Use range of BRS
bars
3) Output ONLY the one line BT
Report?
Many thanks!!!!
herman
if ( ParamTrigger( "Run Com
BT", "BT" )
)
{
WLN
= 0; // the
watchlist to backtest
BRS
= 100; // Number
bars to test
AB
= CreateObject( "Broker.Application" );
AA =
AB.Analysis;
AA.LoadFormula( "C:\\Program
Files\\AmiBroker\\Formulas\\Systems\\Example.afl" );
AA.ClearFilters();
AA.Filter( 0, "watchlist" ) = WLN;
// This gives
syntax error...
AA.ApplyTo

AA.RangeMode
= 1;
AA.Analysis.RangeN
= BRS;
// This
gives syntax error...
AA.Backtest();
AA.Report( "" );
