[amibroker] Help with Trend Continuation Factor from S&C Bonus Issue

["Mike Mann" <mikemann@xxxxxxxxxxxx>]

I'd like to code the TCF presented in this issue and need to sum the 
gains on positive days for the last 35 days, and the same for the 
negative days out of the last 35 days.

I tried the following code for the positive days, but system 
indicates I have created endless do loop......... can someone offer 
a suggestion.  Thank you so much.....  Mike

for( i = 0; i < 35; i++)
{ 
      TP = IIf ( i=0, 0, IIf(Ref(C,-i)>Ref(C,-(i+1)), Ref(C,-i)-Ref
(C,-(i+1)),0));

}

Plot (TP,"TP",colorWhite,styleHistogram);
