Thanks. Your formula should be right. The documentation of Sum is Sum(Array, Periods). I overlook that "Low > Ref(Low,-1) AND High < Ref(High,-1)" is array of booleans which is the beauty of AFL (I originally thought it was only boolean so can't be applied to Sum).
Thanks for help again. ________________________________ From: Mike <[email protected]> To: [email protected] Sent: Saturday, February 14, 2009 3:30:51 PM Subject: [amibroker] Re: EasyLanguage CountIf function What about: InsideDays = Sum(Low > Ref(Low, -1) AND High < Ref(High, -1), Length); Mike --- In amibro...@yahoogrou ps.com, "swstevewong38" <swstevewong38@ ...> wrote: > > New to Amibroker using it about a week. > > Translating a piece of code from EasyLanguge. > > InsideDays = CountIf(Low > Low[1] and High < High[1], Length); > > Think for a while maybe a combination of AFL's SUM, CUM, BarsSince > function can do, but still can't get the correct formula. > > Is there an equivalent way to express that CountIf in AFL without need > to write loop? > > Thanks. >
