Pretty new to trading.. does anybody know how to find out which exchange is the primary exchange for a stock ? I'm trying to figure out if an ETF trades mainly on AMEX or ARCA.
Suppose you have a portfolio all tied up in stocks and it is worth 50k.
How much capital is needed to sell the whole portfolio at the open each day and buy a whole new portfolio worth 50k ? Each day you do this. ( You are turning the whole portfolio over each day ).
Is there some extra...
