I've always found it to be very easy to say that after the bell. I have the same problem as you, though, while the trading is still active. Is this the top? Where is the bottom? Wish I had a book like Marty McFly found. It would sure make it a lot easier.

Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!
