I seem to have a problem when placing orders via IB's ladder. It happens on any order, MKT via a button or a limit clicked directly onto the ladder. The order stays blue for upto 30seconds sometimes, before either going green or filling depending on how far the markets moved since I clicked it. I'm only trading the YM. Does this sound like a PC, ADSL fault or is their a tweak on IB I need to make? Any suggestions appreciated. FYI: XP pro, 4gb ram, athlon dual core, 5mb ADSL, based in UK. My CPU load spikes to a maximum of 60%, average is about 10-20%. I am running, 4 screens with IB TWS and Esignal only. any ideas?
