Andy,
Use the built in Price ROC set at 1.
Remember, in an earlier discussion that I stated the ROC is the same
as C - ref(C,-1)or todays minus yesterdays close.

because what i want is to see the difference between todays close and
yesterdays close as opposed to what u represents in this case the
average up day(s) and d the average down day(s) what i should i have
asked is how do i change the formula so it gives me a representation
of say todays close - yesterdays close so eg todays = 910 yesterdays
close = 905 the diffrence is -10 this set up is the same setup as
linda ruschke uses in streetsmart or am i getting the wrong end of
the stick
