Hi
Is it possible to have a single formula to plot both the sine wave formula below… variable = “W1”
And the vertical lines for the peaks and troughs in the same sine wave
Peaks= “pk “
Troughs = “ tr “
When I try to plot both the sine wave “W1” and “pk” and “tr” I get a miss match with the scaling
The only way I can over come this miss match with the scaling
Is to have two separate formulas one for sine wave variable = “W1” and
second formula for the vertical lines for the peaks “pk” and troughs “tr”
----------8<------------------------------------------------
Period1:=Input("Cycle Period 1",3,1000,179);
B:=LastValue(Cum(1));
Prd:=Period1;
A:=Cum(1)*360/Prd;
F:=2*Sum(C*Cos(A),B)/B;
G:=2*Sum(C*Sin(A),B)/B;
J:=LastValue(Sqrt(Power(G,2)+Power(F,2)));
K:=LastValue(Atan(G,F)*57.29577951);
W1:=LastValue(Mov(C,B,S))+J*Cos(A-K);
pk:=If(Ref(W1,-1)=HHV(W1,3),W1,0);
pk;
tr:=If(Ref(W1,-1)=LLV(W1,3),W1,0);
tr;

Best regards,
Derek

Hi Derek
Part of your question seems to be the same as the previous poster, namely, how to plot two disparate plots in the same window without one distorting the other. Assuming both plots swing from zero to some positive value, what you can do is calculate a reduction factor for one based on LastValue(Highest("plot A")) relative to LastValue(Highest("Plot B")). One of the things that I do with a Trade Equity Portfolio Display is plot the portfolio equity curve along with the number of open trades after applying a reduction factor to the equity curve.
The thing is that you cannot scale one plot of an indicator to the left scale and the other to the right - only one scale can be used per indicator. So maybe you just need to shift the centre line of the sine wave or the FALSE level for the peak/trough markers. I think for these markers you'd probably want to use a histogram. However, applying a bias to the sine wave centre line might be the way to go.
Hopefully these random thoughts are of some help.
Roy
