"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post

Author	Topic: IQConnect crash with 4.1.1.1 (5 messages, Page 1 of 1)

If my app sends "S,DISCONNECT" or if I click the "Exit" command in IQConnect's menu, it crashes immediately. The resulting dialog box complains about an attempt to read memory at 0x00000070. (This is consistent.) Again, has anyone seen similar behavior? Thanks! Allen

This might not be the minimal sequence of conditions required to duplicate the bug, but it seems to be enough to make it 100% repeatable: The app connects to the Level I port and authenticates as usual. The app connects to the Level II port. The customer's account is not authorized for Level II. The app doesn't read from or write to the Level II port, but leaves it connected. The app issues the S,DISCONNECT message via the Level I port, or the user selects the "Exit" command in IQConnect's system tray icon menu. If that's not enough information to duplicate the problem, let me know and I'll send you a couple of IQConnect logs that I captured during a successful run and a failure. Allen

The key was that the account cannot be authorized for level2 in order to duplicate this. I will look into what is causing it. Thank you for the report.
