I have both Scottrade and Etrade. Scottrade has blocked me from making trades numerous times. I opened my etrade account as a result of this. If you research Roger Riney you will see what PTR has suggested. It is a rather incestuous relationship between Roger Riney of Scottrade and Nite. Etrade is its own MM. Both have a fiduciary responsibility to their customers yet only etrade seems to act on the behalf of theirs.
What I am saying is that NITE takes more risk by selling more naked short shares than ETMM. Thus, when they (NITE) find themselves in a bind (overshort), they call Scottrade and other BDs that use them and ask them to bend over and lower their panties by putting a BUY trading restriction so that NITE can manipulate the stock and cover the short before it takes off to much higher levels. It is illegal and they need to be called out on this and hope the government steps in to stop this crime. All the government does to protect shareholders is fine these MMs. IMO, the feds are being paid off to look the other way as these MMs and BDs steal retail investor monies. We all should raise a real stink with the government.
