Aside from speed testing you need to try ping and tracert.
I'm near Philadelphia using 1.5 mbps DSL on interleave. ping gw1.ibllc.com takes 49 ms and tracert gw1.ibllc.com takes the same 49 ms over 9 hops. Try ping and tracert to your broker's server. You could be getting stuck or throttled at a bad internet router somewhere along the way.
In Windows you run ping and tracert from a command line.
start > All Programs > Accessories > Command Prompt
