OK Rumple, I talked to Kevin.
It was a misunderstanding of nomenclature. We were both seeing the same elephant from different angles.
Also I normally use market and stop orders so that’s how I was seeing what you were saying.
Here’s what I got out of my conversation with him;
RE: Bid/Ask
When you are talking about bid/ask, you are talking about the columns of the Market Depth Board, I was hearing market bid/ask that you would see on the price tickers. THAT was the biggest part of it right there.
When you place a market or stop order there can be slippage in a fast moving market.
When you place a limit order (Limit or Better) that means that is the limit of the price you wish to be filled at, but it could be a better price or it may not be filled at all. A sell limit would go into the ‘ASK’ column of the Market Depth Board - VERY IMPORTANT DIFFERENCE. I was hearing that your sell limit was being filled by “market” ask which of course didn’t make sense.
When your sell limit goes into the ask column, you are basically “getting in line to be filled”. As your order moves up the board you have a higher chance of being filled, if the opposite order that picks up your order happens to be better than your “ASKing” price, then you get a better price (which could turn out to be ‘market’ ask. Limit or Better.
I had said something about your order being filled at a better price than you put in for but wrongly called it ‘slippage’. I guess that word only works on market and stop orders and against you.
Again nomenclature (proper titles).
RE Spread;
What Kevin said is “Brokers who utilize ECN technology do not collect on the spread.”
He didn’t say there was NO spread or that it makes no difference. He just said THEY don’t collect on it.
MBT will only charge you the commission (true), but you as the trader will still pay the spread on exit - to the market. If I’m long and market Ask stays still but market bid moves, my floating P/L will change with it.
Now using a limit order can reduce that spread for you because of that better price that can be had, but the spread is still a factor.
Anyway, I now understand what you were trying to say.
