[amibroker] Re: AFL for Buy statement

["Rick" <rickbw@xxxxxxxxxxx>]

Thanks for the help.  I attempted to use the suggested "sum" but it adds the days together as a calculation (sum of last 5 days for the array).

What I really want is to find that a condition existed for the last 5 days (i.e MACD was below 0 for each of the last 5 days).

I browsed thru the AFL's - should I use a nested IIF statement?

Thx!
