For those with Etrade accounts I would relate an experience I had with PTSC. When the trading got very heavy Etrade suddenly and inexplicably changed the rules and would not let me sell electronically. I had to enter each order through a broker although I had bought for many months on-line. They never would give an explanation or allow on line orders. That probably cost me 100K. One of these weeks we will see wild action here. Be sure your broker doesn't change the trading rules. Etrade was a market maker too and I believe that was the real reason for the change of rules. My accounts are now with TDAmeritrade.
