How are things coming along with live trading through Interactive Brokers (IB)? Have any algorithms been launched with real money? What's been learned, in terms of the mechanics of the algorithm (e.g. controls/limits, timing/slippage, costs, monitoring/notifications, etc.)?
Also, if there are live Quantopian algorithms running with IB, perhaps someone would be willing to provide details (e.g. type of algorithm, capital, frequency of trading, etc.).
