I agree, needs a bit more time. I would not short (against trend) yet. My problem is that quite often the moves are quick right at the open and then fairly flat.
Last night would have been a good short around Europe open - nice slow ticking down that could have been a nice ride, but last night I was catching some zzzzzzzz's !!!! And the Asian trade gave no clue as to what was coming ... often it does .... I like the "nice slow trade" over night but it is not an everyday thing. Not likely to get caught in any "limit moves" !!
And, Corn did recover about half of it's overnight drop.
