[EquisMetaStock Group] Re: Category 3 resistance pattern - is my codes ok?

["Jose Silva" <josesilva22@xxxxxxxxx>]

Re "Ref(bingo,3)", forward-referencing has at least two inherent 
problems:

1) Each forward-referenced period introduces a null or N/A bar to the 
final MS plot;

2) Forward-referencing signals gives an unfair advantage to those 
traders that have a window into future events.  ')

The MS code below resolves problem #1:
