Ever time I enter a trade using market order it gets filled 1 cent away from the bid/ask. If this normal? Shouldn't I get filled at the ask/bid. Is this slippage? Is there a setting in TWS I can change? e.g. 13.34/13.35 market buy will get filled out $13.36 This only seems to apply to entering new trades. Also If I try and buy at limit $13.35 again it gets filled at $13.36. Anyone else experience this issue?
