As anyone smart enough to see, the solution is in hidden in this message. However, I see no reason to point it out for free.

Just to make it 100% clear. IB doesn't sell your stops (I never heard of any reputable firm that did this) nor shows or advertises them to others.
It seems to me that you may be using odd lots in your strategy which would impact your fills. In addition, the bots/HFT's don't see your orders on a paper trader which is probably your bigger issue as they can't jump in front of you in a paper account. Strategies these days are much more difficult to backtest accurately when applying to the real world as a result.
