Did anyone has experienced anomalies on IB paper trading acct? I recently had a 15 ticks slippage on 10 CL contracts on a sell stop order…one contract was correctly filled and the other nine contracts were filled at a 15 ticks difference…there was no high volatility at that moment and it happened twice.
IB support told me that this shouldn’t happen on a real acct except that during high volatility (i.e. major announcements, black swan events, etc.).
However, I was wondering about IB forward testing new strategies on a paper trading account. How one can trust the results?

I will assume you have the requisite market data. It's only a paper trading account so it doesn't really matter. I don't think at least in my opinion that Interactive Brokers truly cares about their paper trading accounts. How is it that you know for sure these are anomalous events and not true market prices? what results are you referring to?
