Agreed that the term "free carried" can not be found in a dictionary. But there are many terms that are used regularly that do not "offically" have a definition written somewhere.
e.g "dead cat bounce". Won't find it in a good dictionary, but it gets used on the "news" and business programs often.
So why can't "free carried" be defined.
Yes it has a couple of meanings, but each in their own context.
We all know what is meant by "free carried", when it is mentioned on HC. That is all that matters.
P.S You and Profess are truly correct, the definition is not "official (or legal)" terminology.
But they introduce new terms in the dictionary each year, maybe one year "free carried" may make it...
