Sum up all up changes and down changes
Hi all,
Suppose I have a data series like below A B Data Chg 46.1250 47.1250 1.0000 46.4375 -0.6875 46.9375 0.5000 44.9375 -2.0000 44.2500 -0.6875 44.6250 0.3750 45.7500 1.1250 47.8125 2.0625 47.5625 -0.2500 47.0000 -0.5625 Chg is calculated from minusing the preivous data item just above from the value in the corresponding row. e.g., First exmaple, Chg of 1.000 is indeed 47.1250 - 46.1250 I want one and ONLY ONE function in a cell to calculate sum of all up changes (=0) and all down changes (<0) in Chg column, ONLY using Data Column cells as input to this function. Can someone help? Tetsuya |
