I also do not
understand the logic behind line 6 however, I think the reason your code is
failing is due to your use of the equal sign. When you set a variable you use,
= as in x=c+1;
However when
you are trying to use mathematical equal within the code you must use == as in
c==42

Twiggs Money Flow formulaHi all I have seen
people using this and became curious enough to check it out. It is based
on the theme of the Chaiken Money Flow Index but is designed to better
handle price gaps and volume spikes. Colin Twiggs is behind it. He
has given a Metastock formula for it: periods:=Input("TMF
periods",1,100,21);TRH:=Max(Ref(C,-1),H);TRL:=Min(Ref(C,-1),L);TR:=TRH-TRL;ADV:=((C-TRL)-(TRH-C))/If(TR=0,999999,TR)*V;WV:=V+(Ref(V,-1)*0);If(WV=0,0,Wilders(ADV,periods)/Wilders(WV,periods))
Now even though I cannot work out what the sixth line is supposed to
represent you would think that this was easy enough for me to
translate but whatever I have done is wrong: periods=Param("TMF
periods",21,1,100,1);TRH=Max(Ref(C,-1),H);TRL=Min(Ref(C,-1),L);TR=TRH-TRL;ADV=((C-TRL)-(TRH-C))/(IIf(TR=0,999999,TR))*V;WV=V+(Ref(Volume,-1)*0);TMF=IIf(WV=0,0,Wilders(ADV,periods)/Wilders(WV,periods));
