Hello,
You get "bad args" error because
HighestSince/LowestSince
have different syntax than in MS:
HIGHESTSINCE (AFL 1.4)
SYNTAX
highestsince( EXPRESSION, ARRAY, Nth =
1 )
RETURNS
ARRAY
FUNCTION
Returns the highest ARRAY value since
EXPRESSION was true on the Nth most recent occurrence.
EXAMPLE
highestsince( Cross( macd(), 0 ), Close, 1 )
returns the highest close price since macd() has crossed above
zero.
Note that Nth parameter is last one and it has the default
value of 1 (so it can be omitted).
Note also that <FONT face=Tahoma
size=2>LastValue is something completely different that MS-like
PREV.
LastValue returns the very last value of the array
(looks
into the future).
Best regards,Tomasz
