What you described does not make sense in the slightest. If you shorted and got filled then obviously your broker located borrow for you. Legal? Ticked. You said you then went long an equal number shares. Legal? Ticked. You basically ended up with net zero exposure (not sure why you would do that in the first place as you had nothing to gain whatsoever). But legal? Ticked. You then sold the long position again (your broker says thanks for the double commission you paid in exchange for nothing) and ended up again with short exposure. If you did that with separate brokers (long with one broker and short with another) then there is nothing whatsoever illegal about that. So yes, I call you an idiot because you provided your broker (s) with several free lunches, lol. And your example has nothing WHATSOEVER to do with this thread. And short selling was totally legal and accepted business practice well before the financial crisis. Maybe you should refrain from participating in threads you seemingly have no idea of what the topic is actually about. Enough said.
You do realize split accounts can help a trader short a crashing stock. Back in 2008 when the vix was over 80, I had a difficult time getting shares to short so I would continue to place short orders over and over until I was filled. I then placed an order to go long equal shares in a separate account. About 20 minutes before the close the market would selloff like clockwork and all I had to do was close the long position. The shares to short were never available during this volatility so I had to improvise. I did this with SPY as well because shorting SPY at that particular time was a terrible fill compared to just selling SPY. Anyways, I got around the rules and I'm pretty sure it wasn't legal. Please tell me why I couldn't do this in one account rather then two? How come they wouldn't let me do this? Why did they say it was illegal? Were they lying? Shorting and manipulation were frowned upon back then and still are...just wait for the next big decline to hear it all again. This is related to the issue because I thought the sequence of closing out both positions might be the violation... like my experience with my equities broker. And like I said, currencies are a different world so who knows. So what is your opinion about how I used two different accounts in 2008? Sound legal to you? And once again you are a confusing fellow. You care so much about newbies and others getting confused by idiots and yet so quick to put people down. How do you care so much and then suddenly rip people a new one. I'm trying to be nice and not call you anything because I didn't make it clear that I thought the OP's violation could be some other variable. So, to be clear, you are calling me one of the idiots...right?
