[amibroker] Ref Function

["troll" <deanhodgins@xxxxxxxxxxx>]

I'm puzzled over the values the following example formulas return:

x = ValueWhen( Ref(TimeNum()==73000,-1), TimeNum() );  Returns 73500
x = ValueWhen( Ref(TimeNum()==73000,0), TimeNum() );   Returns 73000
x = ValueWhen( Ref(TimeNum()==73000,1), TimeNum() );   Returns 72500

I thought that the Ref function used -1 to shift reference to a past
value while a positive number refers to a future array value but the
opposite occurs in the above formulas. Not sure why the results are
opposite from expected unless I've missed something here.

Any clarification much appreciated.


Thanks & Regards,

Dean H
