Due to the limitations of the system tester, I have used a graphical approach of
system testing. I gave an example of this in my post :-
3d Aug 98 subject ' System test w/o "re-investment": How? and "System Testing"'
To save you the search, I have listed below the relevant code as well as attaching
the .dta files to enable you to import this code...
(The .gif displays the result obtained in this example and the .dta files contain
the indicator and expert code)
Although this example does not address your specific requirement, it is provided
as an example of what can be accomplished using a graphical approach to system
testing.
Using this approach, you can use any rules you care to define to determine your
buy and sell criteria and prices. The indicator can display your resultant equity
line and the expert can be used to add color to your bars and add buy and sell
arrows.

{example of using the system indicator to demonstrate the feasibility of a given
buy and sell strategy}
{Note this example uses 99% of the daily high as the sell value ... because we may
not necessarily know when the high has occurred we may not be able to achieve this
price ... but then this is purely an example to demonstrate the approach of using
the indicator builder}
buycap:=10000;{capital}
mov3:=Ref(Mov(C,3,S),-1);
{buy and sellpulse occur each time buy or sell condition is satisfied}
buypulse:=Cross(C,mov3);
sellpulse:=Cross(H>Ref(C,-1),0.5);
{long indicates whether we are long or out of the market}
long:=If(buypulse ,1,
If(sellpulse,0,PREVIOUS));
{buy and sellpulse1 occur only at the start and end of going long}
buypulse1:=buypulse AND
Ref(long,-1)=0 AND
long=1;
sellpulse1:=sellpulse AND
Ref(long,-1)=1 AND
long=0;
buyval:=ValueWhen(1,buypulse1,C);
{sell value is 99% of daily high}
trailstop:=0.01;
sellval:=ValueWhen(1,sellpulse1,H*(1-trailstop));
buyqty:=Int(buycap/buyval);
profit:=ValueWhen(1,sellpulse1,
(sellval-buyval)*buyqty);
cumprofit:=If(sellpulse1,PREVIOUS+profit,
PREVIOUS);
buycap;
cumprofit;
buyqty*10;
0;
***********************************************************************
expert ... highlight as green (long) bars by picking up "long" from "m015 example"
highlight (green long bars) ... FmlVar("m015 example","long")
