9 bid at 830.25, 8 offered at 830.50, 8 buys take out 830.50, offer goes to 830.75, best bid is 830.50, my mkt sell is filled at best bid. All in the flash of an eye! Too bad, cause if was any slower, I might change my mind and hang on to my long position cause it looks like it wants to go back up. SPEED KILLS!Quote from Simtrader:
Suppose there are 9 contracts bid at 830.25. Suppose there are 9 individual sell stop orders sent by other people resting on globex at 830.25 ...all of which are timestamped as arriving before your order does. All these orders have to be fillied before you can be. Agreed that if there are 10 contracts bid at 830.25 then you will also get 830.25. But when then there are 9 bids or less ...you will get the next lowest bid at 830.00. You just suffered a tick slippage because your order took lowest priority in filling. Of course there is a queue at every price level. That is how Globex knows which orders to fill when.
Maybe most of the time you will also get the same price. But when prices spike quickly and there are fewer/bids offers at a given level, then you risk suffering a tick slippage for no other reason that you are using a service who handles stops in a crappy second rate manner. Sorry if you don't understand how globex fills orders.
Quote from profitseer:
And another thing, where is this long line I need to wait in for a stop or mkt order? If I have a sell stop or sell mkt order and the bid is 830.25, what line do I have to wait in to sell at 830.25? If 830.25 is my sell stop, then my sell becomes mkt at 830.25 and what is going to prevent me from getting filled at 830.25?
There are already plenty of traders trying to sell at 830.50, and some of them are successful, I am merely trying to sell at the bid. Who do I have to wait behind? Show me this long line of sellers at the bid. I have never seen them. I don't think they exist except in the mind of some fearful disoriented trader wannabe.
