Ron, What I sent was able to be just put into the IB and Apply. If you
scroll back (or zoom out) you will see digits along the bottom. I will
modify it to show arrows with buy signals. The buy signal will be on first
trading day of each week.
Plot(C, "Close", colorBlack, styleCandle);
//buy signal is at first trading day of each week
Buy = DayOfWeek() < Ref(DayOfWeek(),-1);
//find lowest price on the screen and call this price Z
cansee = Status("barvisible");
First = Cansee AND Ref(Cansee,-1)==0;
Last = Cansee AND Ref(Cansee,1)==0;
z = Ref(LLV(L,Last-first+1),-BarCount+1+Last);
// plot green up arrow at each buy signal
PlotShapes(shapeUpArrow*Buy, colorGreen, 0, z, 5);
The plotshapes will be green, on layer 0, located on the value of Z which is
the lowest price on the screen, and offset by 5 pixels.
Cheers,
Graham

Graham, thanks a lot for your quick response.
I put your creative code in an indicator window, but I have no idea of how
to make it work.
I am more likely to understand the concept of Cold Fusion than this
confusing creative coding of your's.
Hopefully, I will be able to start to understand "layers", "yposition" and
"offset" when I am able to see the User Manual Example modified to plot the
arows at the bottom of an indicator window. Thanks, Ron D
