where Return, StockQty and Date are all data lists, and ConfidenceLevel is an input value from a slider. This formula should come back with a value of 0 for where the two are not equal, and -1 for where they are. The RHS of the equation is simply calculating the nth value of the list to match. I am unfortunately unable to get the correct value this way. I can, however, get it if I just plug in a value as such:
Rank(sum(Return * StockQty))=15
Could someone help me figure out how to use a formula correctly in the RHS of the Rank function?
