[amibroker] Re: Difference between IB and Esignal data

I don't have a definative answer to your question, but I see the same 
thing.  I'll often get filled by IB 1 or 2 pennies ABOVE the highest 
price printed on either TradeStation or e-Signal.  I don't think it is 
a IB data issue.  I don't subscribe to any IB data.  They just take my 
order via Ninja.  It's possible IB is paying for order flow.  

I do nootice that it only happens sometimes.  I've even tried inputing 
orders simultaniously with IB & TradeStation to see if there was a 
difference in the fills.  There was not in the two snapshot test I did
