In TASC September 1988 the above article included an indicator and a system. The Metastock code for the indicator was given in Traders' Tips but the system was provided in Tradestation / Supercharts code. Both can be found at this link www.traders.com/Documentation/Feedbk_docs/Archive/0998/TradersTips9809/Tips9809.html

I have tried to translate the system code in MS as follows:

F:=10;
LookBack:=10;

Resistance:=ValueWhen(1,Cross(Mov(C,LookBack,S),C),HHV(H,LookBack)); Support:=ValueWhen(1,Cross(C,Mov(C,LookBack,S)),LLV(L,LookBack));
Rr:=Resistance / (1+(F/100));
Ss:=Support * (1+(F/100));
sma:=Mov(C,LookBack,S);

LE:= (Cross(C,sma) AND C<Rr) OR Cross(C,Rr) ;
SE:= (Cross(sma,C) AND C>Ss) OR Cross(Ss,C) ;
LX:= 0;
SX:= 0;

Would appreciate if somebody could check the above. Thanks.
