Using BEST execution, I tried to short 100 shares at the limit price of 20.20. What happened was that a 100 share offer appeared to show up on BTRADE, but it was priced at 20.49.
Are you certain that this is BTrade's policy? Is there something in writing somewhere that says this?
What you are describing looks like the standard "mark-up" that occurs for short sales, either to the previous day's closing price (Island, Instinet) or using the uptick rule for the last trade on that ECN (REDIBook). However, this is my experience with
listed stocks, not NASDAQ. That's why I ask where the rule is written.
I contacted IB via telephone and discussed the problem with an IB representative, but by the time he understood what I was talking about, the 20.20 bid had disappeared...
The existence of a bid there (or not) should not affect what happens to your order. Perhaps this added to the c/s person's confusion.
There are sometimes where what I am trying to take is an offer and I'll see my bid go in to the BTRADE ECN but at a modified price and I won't get a fill.
This, of course, makes no sense at all, unless maybe BTRADE thinks that it sees a lower offer out there and is marking down your bid to avoid crossing it? Is this supposed to happen in the pre-market? If so, that could also explain what's happening with the short-sales (that it thinks there is a 20.48 bid out there, and is marking you up to 20.49 to avoid a cross).
The IB representative started getting upset at me and asking me if I had any proof that the price of my limit order was being modified and all I could tell him was that it appeared that a 100 share order went in to BTRADE but at a modified price. When I cancelled my order, that same 100 share order was immediately cancelled. After the representative became more belligerent, I ended the chat.
This is an unfortunate pattern with some of IB's c/s people - when they don't have an answer, and we get frustrated with them for not understanding the basics of electronic trading, they react badly. What seems to work for me is that when I see the conversation escalating negatively like that, I just get really, really, nice. At least that shows the person you're talking to that you are willing to stop the escalation, and be the better man. If that doesn't work, I simply give up :-(
I'd suggest that you take your posting and send it in an email to IB. When you take the time to document something this well, it has a decent chance of getting to someone that can understand and resolve the problem.
