Can price pass you?


If you have a contract in at 1500.00 and you have an exit at 1500.25... Can the price reach 1500.50 without fulfilling your order?
With Stops, yes.

A stop becomes a market order once the price is hit. In fast markets, like right after a significant announcement, there may be a huge entry of market buy orders, with a much smaller number of limit sell orders in the system. As a result, the market continues to move up until all buy orders are filled. Your stop order may become a market order after the news related buy orders are entered. As a result, you're at the back of the line. I once had a $1000 slippage on a 30 year bond trade. It hurt.

As a day trader, I usually stay out of the markets when key announcements are being made. I pay attention to scheduled announcements. Last year, I saw the e-mini S&P trade up 8.00 and then down 5.00 in the first minute after an 8:30am announcement. I also have CNBC on while I'm trading. If they say Obama or Boehnner is making an announcement, I stand aside.

Hope this helps.
Perfect. THANKS!

If you are long from 1500. and the price gaps on the offer above 1500.25 you are guaranteed a fill
That was a limit order

If you are short from 1500 and your exit is at 1500.25 as a Stop, you are not guaranteed a fill because Stops have Limits to them. If they surpass the limit, the exchange may not honor your stop.
