Hello, Can someone please explain the logic behind Interactive Broker's implemenation of stop orders for Nasdaq stocks? I'm not looking to debate how unusual their implementation is: It's been done before on the boards and clearly we can all agree that it's unusual. What's not clear to me is why IB chose to implement the stop in this manner. What advantages does this methodology give the trader? I asked IB's help this question, and their response was: "The reason why we have this logic on the NASDAQ stocks is due to the volitility on the Stock." This is a pretty weak response: there are many large cap stocks on the Nasdaq that aren't that volatile. I'm hoping that one of you can provide a more logical reason than this. Thanks. -- Punter. P.S. Here's how IB handles stop orders for Nasdaq stocks: "In regards to NASD stocks and US equity option, IB will elect Buy-Stop orders only after we see a bid at the stop price and subsequently confirm a second bid. Only after we confirm a second bid will we send in the order. Likewise, IB will elect Sell-Stop orders only after we see an offer at the stop price and subsequently confirm a second offer. Only after we confirm a second offer will we send the order."
