Data analyze and find patterns in google sheets data

Hey Folks, I have 20 independant sheets full of data located in google sheets that I would like analyzed. I am looking for any statistically significant patterns between the variables X,Y and Y/X across the given dates. Specific things I am hoping to find are: -When future X is most likely to go up in relation to past X, Y and(or) Y/X data. -When future X is most likely to go down in relation to past X,Y and(or) Y/X data. -When future Y is most likely to go up in relation to past X, Y and(or) Y/X data. -When future Y is most likely to go down in relation to past X,Y and(or) Y/X data. All sheets are INDEPENDANT from one another BUT I am hoping to find statistically significant patterns that are able to apply to all sheets. Please start your message with 'ABCDE' Enclosed is a screenshot of a chunk of examplary data (there are 20 sheets worth of this type of layout) Thanks
