I can see that when I request real time trades, there is a field named "Message Contents" that can have different values. Some of these values are the following:
C - Last Qualified Trade.
E - Extended Trade = Form T trade.
O - Other Trade = Any trade not accounted for by C or E.
I understand C and E values, but I was wondering why some trades are classified as O. Is there any reason for this? When is a trade considered as O?

The exchange has many trade conditions, many they mark as non-last qualifying. The O designation is the bucket we use for those.
A common example would be an oddlot trade. These are trades of less than 100 shares that, generally, do not show up in most trading apps. The reason being is that it helps to prevent people from manipulating the current market value by buying one share at an unrealistic price.
Each exchange is different in what their requirements are for what is last-qualifying and what is not. But, the C, E, and O designate is how we try to simplify all of that for you, so that you don't have to parse out the trade conditions yourself.
