there is a trade session right after ward
although not the FIRST one, but the best one (i think)
just dont be shy, everyone is friendly,
ASK whos binder it is before you look or touch
make eye contact,introduce yourself, and that person will generally
(if not busy) will ask to see yours size does not matter,
if you cant make an even trade, some money can exchange to sqaure up
at least that was the rule in the past, but exchanging money is frowned upon
its fun and everyone finds something
