I am working with a mutual fund and am trying the following:
iif(close>ref(c,-16),1,iif(c=ref(c,-16),0,-1))
am comparing the close today to the close 16 days earlier and
assigning a +1 if it is greater, 0 if it is equal and -1 if it is lower.
I want to compare todays price with the price 16,17,18,19 and 20 days
earlier. and repeat the same with prices for the preceeding 5 days.
and sum all the values obtained.
Not being a programmer, I see that I have to write a lot of lines. Is
there a simpler way?
TIA
