Price difference between limit and filled

Hi,



Can someone explain why the limit order price and filled price are different?

Hi, Sungtae:



At C2, we automatically change the prices we display to reflect the actual prices received by real traders in live brokerage accounts.



The reason that some traders may not have received the limit price is that the market may not have traded through the limit (i.e. the limit may have been just touched). In cases like this, AutoTrading software typically converts a limit order to a market order.



Thus, one of the cool things about C2 is that you can really see how a system might actually perform in a real-world setting, since things like slippage, AutoTrade latency, etc. are already baked into the hypothetical results you see here on C2.
