    Opening Orders - 2008

    I would like to use OPG strategy on canadian stocks. the problem is that IB told me there is no OPG order with TSX exchange. I wonder how i can get the opening price for my order. I wonder if any one can have the answer, especially Don, since he has an office branch in Canada. Many thanks.

    Can someone help me on the IB commission problem?

    fhl, even if my order hit others, that still can not explain the problem. In the first example of LCRY, there are two partial fills, each of 100 shares, executed on ISLAND. ISLAND will charge 0.003 to take liquidity, plus 0.002 for commission, I will pay 0.005 *200=1 dollar before sec and...

    Can someone help me on the IB commission problem?

    jimrockford, I also though about that my limit order hits others. but in fact, It is unlikely. This is because I sent the limit order very early, and it was sitting there for long time before it was executed. Though I change the price constantly, but each time, I only change price to the bid...

    Can someone help me on the IB commission problem?

    The following problem has puzzled me for some time, and it is so hard to get response from IB customer service even if I pay them 5000 dollars commission each month. They should use my money to hire more people. Hope someone here can give me some answers. I am a rebate sensitive trader, and...

    IB charged higher commission since Feb.1?

    I am still puzzled why I was charged more commission in Feb than in Jan, i.e., $0.88 vs. 0.38 for 200 shares of OPG limit order. This happened to all my OPG limit orders. In my previous post, I thought SuperSoes may have changed fees in Feb, but it seems SuperSoes fee on OPG limit order was...

    IB charged higher commission since Feb.1?

    generally unbundled structure is cheaper than bundled, but depending on your trading style. if you consistently remove liquidity, it could be more expensive than bundled.

    IB charged higher commission since Feb.1?

    I possibly figured out what was happening is that ECN rebate has been changed since Feb. For example, for OPG orders, ECN is now charging 0.0005 no matter it is a limit or market order. Before Feb.1, I think superoses credited 0.0022 for OPG limit orders.

    IB charged higher commission since Feb.1?

    Did anyone notice that IB charges higher commission since Feb.1 under unbundled fee structure? My daily commission almost doubled in February relative to January even though my trading volume remains almost identical. From the statement, it is clear there is no rebate pass through from...

    OPG order with better price not filled

    I submitted an OPG sell order of 200 shares of stock TESOF at $18.04. the stock opened at $18.24. I looked at the IB intraday 1 sec data, it shows the stock opened at 9:34:45 with 2 shares (I guess in IB historical data, 2 means 200 shares here), at $18.24. Since my price is much better than...

    does OPG order affect open price?

    thank u, nazzdack. but IB says the OPG order will be filled or cancelled at the open print, which i interpret the OPG order does not involve in the open price determination process. For a order to be part of the open price, it has to be a direct route to the NYSE exchange, since nasdaq does not...
