Sometimes it makes erratic moves up or down and it lasts one day then returns to flat.
The only way for me is to use these moves and trade them. I was buying on the way down from 3 to 2.10 10 cents intervals and 5000 at the time, then I was selling them at 10 cents profit each lot on the way to 3.11 Now I am waiting for another round of insanity. So, I keep moving my 4.50 down. But it is slow and risky process. I will eventually get caught on the up or down..
