Hi Finn,
sorry for the loss you took,
but I cannot understand, why you limited your possibilities for execution of stop-loss order at your price by using only Island ECN.
When using only Island, you cut off about 90% of the possible market for your order. This has nothing to do with your Broker, be it Datek or MB Trading.
It was most probably your selection of order-route which caused the trouble.
Island is for some stocks the biggest single marketplace among the many ECN's, but even Island counts only for roughly 10% of the volume traded in DELL and many other Nasdaq stocks.
( today, Dell traded 38.9 Mio shares in total, of which 3.4 Mio were traded on Island; less than 10% of Dell's trading volume !!! )
So if you set a stop-loss , this means, you want to be out of this trade a your price, no matter who fills the order - be it Island or any other ECN. In this case, you can either monitor your L2 data closely and enter a limit order but not assigned to a specific route, or you enter your order in advance with Auto-routing enabled.
BTW : if you use specific routing to an ECN or MM with Datek, the 60 second commitment from Datek will not be applicable, since MM's have up to 3 minutes to honour their quote.
If you use Auto-routing with DatekDirect and a marketable trade takes longer than 60 seconds to execute, commission will be waived ( as usual with Datek, I had this happen 2 times last week ).
Even if you use a specified route other than Island with DatekDirect, your order will always be routed to Island first for a possible match. This takes , according to Datek, about 0.2 seconds extra time.

Please read this mail from Datek :

Explanations :
1 Datek Direct is a tool, as the name implies, that allows customers to direct their Nasdaq orders to a specific execution venue. The name should not be deemed to imply that a customer is dealing directly with the marketplace. All orders are processed through Datek Online Brokerage Services LLC, a registered broker/dealer. Please note that, once you have activated Datek Direct, all of the other features in your Datek Online account will continue to operate without change.
2 Datek's 60-second commitment does not apply for orders placed through Datek Direct unless Auto Routing is selected. This is because trading rules allow market participants up to three minutes to respond and execute or return your order.
3 After February 28, 2001, Level II quotes on the Streamer system are available FREE of exchange fees for non-professional users if you trade with Datek more than 20 times a month. Trade less and you still can access Streamer Level II quotes for the modest exchange fee of $9.99 per month for non-professional users. Prices and availability are subject to change.
High volumes of trading and volatility may result in executions at prices significantly away from the price quoted or displayed at the time of order entry.
System response and access times may vary due to market conditions, system performance, and other factors.
regards
Good Luck &
