I've read all the responses that have followed this message, including the restatement by JD that includes the missing inside market information, and one response that echoes my bewilderment at the scenario with the inside market 3 points out of step with the Island book. I'm coming back to this question to get some clarification about ISLD and the CyberTrader interface. I really want no part of the slings and arrows; I declare my neutrality. To avoid the issue of the curious inside market in the example, lets change it to a more probable 121 x 121 1/8 to go along with the Island book at: Bid **** Ask $120 300 **** $122 600 $118 500 **** $123 1000 117 1/4 600 **** $124 5000 For a time I was trading on a system that would in fact reject a limit order to offer on ISLD at $117 because that system checked all orders for cross or locked conditions, based purely on the inside market, rather than letting the ECN resolve the order internally. That system simply would not pass the $117 order to ISLD. On this point at least, JD's generalization is not correct. There are other systems that would reject such an order. The system would, however, allow a SNET order preferenced to ISLD, with the downside of only getting executed for the number of shares at the inside of the ISLD book, in this case the 300 at $120. Even if I was willing to sell lower, ISLD would only execute the 300 and cancel the rest of my order. Or worse, if before my order hit ISLD someone posted an ISLD bid for 1 share at 120 1/2, I would sell 1 share and watch in horror as the market ran away before I could reload an order. The clarification I would like is what would happen if I place an order in CyberTrader to offer 1000 shares on ISLD at $118 1/2 instead of $117. Would I get 300 @ $120 with the balance of my order cancelled, or would I get nothing because part of my order was not executable, and could not be posted without crossing the market? And what does happen to a SNET order preferenced to ISLD if the top bid in the ISLD book does not fill my order? Does it get filled as far down as my limit price, or do I just get the top order in the queue. Is there any reason (such as fees) why, if I was using CyberTrader, I would want to send a SNET pref to ISLD or some other ECN instead of posting a limit order hoping to get crossed internally. Thanks in advance.
