show me on a chart .. tick where oil moved 50 cents in one second? only time is on wednesdays at 10:30 eastern eia report.. i think you are misunderstood?
Personally, I've used hundreds of stop market orders on the QM mini, and get next to no slippage 98% of the time.
This I agree with too. Stop Limits have been by-passed many times for me, and your left sitting there with a limit order. If you leave a big enough buffer though - this might solve it, but even still I wouldn't trust it.
Sadly I don't have a tick chart for it. I trade OTC power and just happend to glance at crude on webice. With webice you can see the entire depth of the book, no matter how many orders. I remember the offers had really really thinned out because they had been lifted so quickly. I'm positive it happend because I even looked at the T&S with a co-worker of mine. The trade was transacted as an outright and not a spread.
