Excel: Ignore the last value in series 1 if COUNT(series1) > COUNT(series2)












0















I am currently using excel to do some trading. In one series I have a column of "buy prices" and the column next to it is "sell prices".



I want to divide all of my sell prices by all of my buy prices to make a quick percent. However, I sometimes have one more buy price than sell prices. The extra buy price throws the percentage off a bit.



Is there a function that will ignore the last buy price in the "buy prices" column when finding the SUM of that column? I will be replicating these hundreds of times using different strategies and really do not want to manually delete the last buy price.
