I think it's like this:
A-L is for the calls from Jan-Dec... A=Jan B= Feb etc
M-X is for the puts from Jan-Dec... M=Jan N=Feb...
A-L = 12 letters
M-X = 12 letters
Don't know what E or OG stands for... I though mayb E is for European?... Or different contract sizes?
You sure these aren't warrants or something?
