I sent you an earlier reply that clarifies my question. I clicked on the "apply indicator" icon in Formula Editor and only saw trade arrows and a split screen showing both price bars and a candlestick chart.. I'd like to see an upper line that shows the upper part of the channel and a lower line that shows the lower part of the channel. Again, thanks for being patient with me. Also, here is the code I used.... Plot(C,"C",colorBlack,styleCandle);
pds=30; Buy = C > Ref(HHV(H,30),-1); BuyPrice = Ref(HHV(H,30),-1); Sell = C < Ref(LLV(L,30),-1); SellPrice = Ref(LLV(L,30),-1); Buy = ExRem(Buy,Sell); Sell = ExRem(Sell,Buy); Thanks Howard Wally --- In [email protected], "Howard B" <[EMAIL PROTECTED]> wrote: > > Hi Wally -- > > You will have seen my private message to you by now. > > As I read this thread, I think I see your problem.
