I have an account set up with IB and intend to daytrade the ER2. Can anyone tell me what they have experienced with IB in terms of time to execute a trade (at the market for instance)? (My prior trading has been done through a broker in a longer timeframe up till now and I'd like to get a feel for how quickly trades execute when I click the transmit button.) Slippage is always a concern. Thanks in advance for comments.
