I'm after some help on applying a formula to a database, that returns the % change in Odds from Open to Close. Maybe walkermac, Excel Cup 2014 winner, could help?
From the attachment, you have varying numbers of fluctuations for each runner.
For example:
Golden Sally Open = 5.3, Close 8. Therefore % change = 150%
Nuclear Power Open = 9.8, Close = 14. Therefore % change = 143%
I could put the database into a pivot table but there's no standard function to carry out this calculation, only Sum, Count, Average, Max, Min, Product, Stdev & Var.
This new function if possible (hopefully not in VBA) would allow me to quickly scan large databases and look for correlations in steamers/drifters and their strike rates.
Thanks in anticipation.
