This thread was originally created in the Traders room by Sonofagun, he has given me his kind permission to copy it over to here for you all to read and to add any of your experiences.
If we all come together we have the power to change things.
I also recommend to those who haven't subscribed to gain access to the Traders room, to think carefully about doing so as there is a wealth of information in there, including trading tips, tactics, etc, it's very busy and well worth the money in my opinion.

So basically CMC avoided most questions (not surprised at all as they are regulated by the FSA). I could never see them admitting that they knock out stops for their own personal gain (a rope and tree comes to mind) although I have to say that recently my fills have been a tad faster so who knows, all the effort that went into the meeting may have made a difference. The future will tell if CMC will listen to its customers, one thing is for certain is that we should all still keep recording on this thread all the problems that CMC give out to us on a regular basis, as we have the power to try and change things, as WE are their bread and butter.
