Yeah, I had trouble getting my sell orders with e-trade at the top of the first bounce. I tried to adjust it a few times but no go. Once it hit 3.20, I just waited for the next bounce and luckily my order went through on that one at 3.30. My two buys both went through OK, but both took a little while to register.
This is why I trade Freddie BTW. Since Fannie has higher volume, I suspect it has even more problems with orders not going through during crazy moves like these.
