excellent!! this is just what i was looking for. may i ask one more
question? what if i wanted to change the formula to make it so it
skips 2 days, as opposed to one day, or skips even 3 days? i tried
to change the inputs with no luck.
also, changing this line in the formula:
Cl:=ValueWhen(1,signal,Ref(C,-1));
to
Cl:=ValueWhen(1,signal,Ref(C,-2));
only seems to have an affect on the starting point, but the moving
average calculation is still skipping just one. to elaborate....
$1, $2, $3, $4, $5, $6, $7, $8, $9
the original formula you provided used ((8+6)/2)=7 to correspond
with price $9, and ((7+5)/2)=6 to correspond with $8.
changing Ref(C,-2) to Ref(C,-1) in the formula makes it so
((7+5)/2)=6 corresponds with $9 and ((6+4)/2)=5 corresponds with $8.
the starting point skipped two, but the formula itself is still only
skipping one.
how would i make it so the -formula- skips two (or three, or four)
as well? so price $9 would have a moving average point of
((7+4))/2)=5.5 and $8 would have ((6+3)/2)=4.5 ?
i cannot thank you enough. this is the last time i will waste your
time :)
