Rudolf .... I agree that you may have to leave the system tester behind.
However, you can achieve constant (level) investment using the graphical
approach. I have attached the code and a .gif file to illustrate the
implementation of the MACD 13,34,89 indicator, trading the zero crossover (on
the long side only).
{m010 MACD 13,34,89 indicator code}
mov13:=Mov(C,13,E);
mov34:=Mov(C,34,E);
mov89:=Mov((mov13-mov34),89,E);
plot:=mov13-mov34-mov89;
{plot;
0};
{m010 MACD 13,34,89 profit code}
buypulse:=Cross(plot,0);
sellpulse:=Cross(0,plot);
{buypulse*50;
sellpulse*50;}
buyval:=ValueWhen(1,buypulse,C);
sellval:=ValueWhen(1,sellpulse,C);
{buyval;
sellval;}
capital:=10000;
buyqty:=Int(capital/buyval);
{buyqty};
profitlong:=ValueWhen(1,sellpulse,buyqty*
(sellval-buyval));
{profitlong};
cumprofitlong:=If(sellpulse,PREVIOUS+profitlong,PREVIOUS);
cumprofitlong;
long:=If(buypulse,1,
If(sellpulse,-1,PREVIOUS));
I set this code up as two separate indicators. One to show the MACD indicator
only, and the other to go on to calculate and diplay the profit. This was done
to display different colours and to simplify the scales being used. Finally I
picked up the "long" variable in an expert to colour the bars green while long
and picked up the "buypulse" and "sellpulse" variables to add buy and sell
arrows. You may want to display the other variables being used in the
calculations to satisfy yourself that the result is valid. These are enclosed in
paretheses {}.
Although a somewhat cumbersome workaround, I have found this approach can solve
some of the limitations of Metastock.
Best Regards ... Martin
