Hi Jerry,
Thanks again for the help. Yes it runs fine on my system as well but
I'm not seeing the actual Donchian Channel on my chart. I guess I'm
not explaining my situation well enough . I'll try again. I'd like to
see the actual Donchian channel displayed on my chart. I'm using the
ETF symbol "SPY" (S&P 500 index).
Below is a link that shows what the "Donchian Channel" looks like on a
chart. Forgive me if you already know this. I'm just trying to clarify
my question.
Please see....(or just go to Google "Images" and search for "Donchian
Channel" and you will see all the charts the show a Donchian Channel"
that I am trying to show on my chart.
