[amibroker] Re: Help - SQRT and Peak won't play nice

["cby" <cby1@xxxxxxx>]

Jayson,

Works. Sweet. Thanks. Now - I obviously have a conceptual AFL problem 
here - when can one just use C (or any array name) and when does one 
have to use LastValue? For example, a buy test of C > Ref(C, -1) 
would be legit, but a formula has to use LastValue?

Thanks again,
Chris
