[amibroker] Re: Need help to convert MS code to AFL

["paul_79c" <paulyes@xxxxxxxxx>]

Here is the code adapted to Amibroker, please note that i did not
verified the result. The code for Metastock is a example of what a
skilled guy can do with Metastock (Jose Silva), however this is the
limit of metastock, with amibroker however you can do much more and
things like this much more easier. I dont have installed metastock
anymore so i could not check to see if the plot matches but it should
because the functions result is the same. 

prm=Param("Plot",1,1,2,1);
start=TroughBars(C,5,1)==0;
end=PeakBars(C,5,1)==0;
value=V;
init=Cum(IsTrue(start+end))==1;
flag=ValueWhen(start-end!=0 OR init,start,1);
start=flag*(Hold(flag==0,2) OR start*Cum(start)==1);
end=(flag==0)*(Hold(flag==1,2) OR end*Cum(end)==1);
acc=Cum(flag*value);
accVal=acc-ValueWhen(end,acc,1);

Plot(IIf(prm==1,accVal,start-end),WriteIf(prm==1,"accVal","start-end"),colorRed);
