I spent my time to search competitive commission, as follows
1)For unlimited $4.95 in TradeKing
https://www.tradeking.com/
and in MB trading
http://elitetrader.mbtrading.com/stocks.aspx
2) For limited 100 shares, $1 in IB
https://www.interactivebrokers.com/en/index.php?f=1590
A) Are these two the market best?
B) Is there any criteria to choose, depending on the trader's frequency? I guess different traders will choose either 1) or 2), for cost minimization.
