outside down day? i don't know if you can recognize signs of the top just within a single day (unless a hugeass drop) but more other technical indicators that might allow someone to catch it within a week or 2.
Keep an eye on the "mainstream" media; i.e. magazine covers, newspapers, tv broadcasts, blogs and websites like this. When sentiment seems too lop-sided, be careful, be very careful.
A few guns go off in the Persian gulf and crude rallies three bucks!

I think it's called the USA.
