I understand that in the Zig Zag formula we input a minimum
percentage to calculate the zig & the zag. Given the minimum %, how
can Jose's Zig Zag formula below be modified to include an output
that tells us the percentage rise and fall of the prices at the zig
zag points? The percentages would be triggered by Jose's buy(+1)/sell
(-1). I think this uses the valuewhen function, but I am have
trouble with it. When calculating the rate of return ((ending value -
beginning value)/beg value) it would use the high price at peaks
(+1) and the low at valleys(-1). The output would look like Jose's
"Price peak/trough cycle length v4.0"
zzper:=20;
pds:=2;
plot:=Input("[1]Cycles, [2]Cycle Avg, [3]Avg StdDev, [4]
ZigZag",1,4,1);
pk:=PeakBars(1,C,zzper)=0;
tr:=TroughBars(1,C,zzper)=0;
lastBar:=Cum(1)=LastValue(Cum(1));
lastLeg:=lastBar*LastValue(BarsSince(pk OR tr));
CycleUp:=pk*BarsSince(tr);
CycleUpAvg:=
Cum(CycleUp)/(Cum(CycleUp>0)+.000001);
CycleUpStdDev:=Stdev(CycleUp,pds);
CycleUpStdDevAvg:=Cum(CycleUpStdDev)
/(Cum(CycleUpStdDev>0)+.000001);
CycleDw:=tr*BarsSince(pk);
CycleDwAvg:=
Cum(CycleDw)/(Cum(CycleDw>0)+.000001);
CycleDwStdDev:=Stdev(CycleDw,pds);
CycleDwStdDevAvg:=Cum(CycleDwStdDev)
/(Cum(CycleDwStdDev>0)+.000001);
statCycle:=CycleUp-CycleDw;
lastLeg:=If(ValueWhen(1,pk OR tr,statCycle)<0,
lastleg,-lastleg)*lastBar;
cycle:=statCycle+lastLeg;
zz:=Zig(cycle,zzper,%);
plotUp:=If(plot=1,0,
If(plot=2,CycleUpAvg,
If(plot=3,CycleUpStdDevAvg,0)));
plotDw:=If(plot=1,cycle,
If(plot=2,-CycleDwAvg,
If(plot=3,-CycleDwStdDevAvg,zz)));
plotUp;plotDw
I would like to use this to look at the historical cycles: rises &
drawdowns of an investment. Jose's formulas on zig zag length have
been very helpful in this analysis. For me anyway, the combination
zig/zag length & % rise/fall is more meaningful than modern
portfolio theories mean, standard deviation, beta & alpha.
Thanks for your help.
