Mike,
Use ref(*,-5) to display a condition originating/occurring five days
ago. Lookback creates a rightshift on chart indicators as recently
pointed out by many on Walter Lake's dbl mavg query this weekend. For
exploration and system tests it creates a similar delayed response;
whereas the clairvoyant +5 gives advanced warnings when used in
historical contexts.
