I am wondering about the meaning of "in the leading position", Thanks
I am wondering that "A is in the leading position in the trade" means A is the No.1 or A is in the top 3 or top few.
Thanks a lot~

Answer

In this context it seems to mean A is number 1, because it refers to only one leading position (singular not plural) 
If it said "A is in one of the leading positions (plural)" that would imply it's in the top 3/4/5/whatever 
Hope that makes sense.
Peace!
