As some of you may have realised, markets are a little over-active this week. Regarding IB: The network connection is fine, but this bloated Java TWS thing "hiccups" each time much market data comes in. CPU - Useage goes to 70 - 100% for a few seconds, the whole "software" freezes as it processes the data. May have to do with that dumb Java garbage collection. Not good. really !!!!
