Isn't ref (c,+14)supposed to be for 14 days in the future? The
example has for only 12.
REF
- reference past/future values of the array Trading system toolbox
SYNTAX ref( ARRAY, period )
RETURNS ARRAY
FUNCTION References a previous or subsequent element in a ARRAY. A
positive period references "n" periods in the future; a negative
period references "n" periods ago.
EXAMPLE The formula "ref( CLOSE, -14 )" returns the closing price 14
periods ago. Thus, you could write the 14-day price rate-of-change
(expressed in points) as "C - ref( C, -14 )." The formula "ref( C,
+14 )" returns the closing price 12 periods ahead (this means looking
up the future)
