min_thold=0.025;
thold=Max(min_thold,Median(ln(HHV(H,2)/LLV(L,2)),100));
thold=IIf(IsEmpty(thold),min_thold,thold);
//
't' is a multiplier of 'thold'
// the larger the value of 't', the more
significant the
// turning point. Adjust it by opening the Parameter
window
// (press ctrl-R)
t=Param("significance",2,2,6,.1);
//
initialization of variables
d=init=trig=HH=LL=z=0;
// main
body
// this program is different than the canned zigzag in that
// it
is symmetrical, it does not use percentages, but rather
// log differences.
close price is not used either. high and
// low trades are used. an
additional item is the trigger
// indicator. it shows the point where the
zig or zag was
// identified.
for(i=1;i<BarCount;i++){
