. My jtrader commission is less than IB for futures, but I am 1st to admit the option commision on equities is what keeps an account open for me at IB. And the key as always for me, I can talk to someone immediately if I screw up or an exchange decides to play the screw up game. One ring and I'm talking to someone who can take care of what I need. My conclusion is that the whole JTrader system design mustQuote from tango29:
Jtrader is a solid platform if you are with a good clearing firm. Only time I had a problem was when I went with a firm that used Jtrader via RCG. RCG had awful tech support of jtrader and I had the problems described. When I switched clearing firms my problems all dissappeared. Not one problem releated to jtrader platform.

Quote from saschabr:
AAA,
what you are referring to,
probably with integrated charts etc.
would be a real pain if programmed
in java, because java performance
is horrible due to interpreted code.
windows would open slowly and
cpu usage would be high.
what you propose would force
IB to write a real .EXE app in C++,
I doubt they gonna do this soon.
Quote from saschabr:
i think the commissions are at their low limits. major part is the exchange fee and
clearing costs. there is not very much
room to lower. maybe IB could go down
to 2.00, but these $.80 saved in each RT
would definetly not revolutionize trading
