buy stop is at 7% loss point
328M shares outstanding, I don't see a "gap up" next morning in this sector unless huge overnight drop in oil.
With a 7% risk on this stock, I agree the chances of a gap that will exceed the stop is pretty much in Black Swan territory.
Just curious if you've borrowed the shares to short or if you're using options as the tool.
Another double edged sword (aren't they all?) using options but it does give one a lot of leverage with a pre-defined risk total.
