Every morning I do a "ping" command to the IB server (gw1.ibllc.ch) to get an idea of the delay that my orders can get to be filled. Last fews months, i had some time response around 140 ms and quite often under 100 ms. But lately, it has been around 200 ms. (Too bad, i should have done a "traceroute" command to see where do the delay increase come from) However, I don't have to complain about that because my orders are still well filled. But I'd like to have an idea of what kind of time delay do others traders have (with IB or other brokers). What kind of time response should I expect ? Is 200 ms still acceptable ?
