I've been trading the TNA for the past couple of months. What I am doing is buying 1/3 the vallue of my account and treating it as a full position. So of coarse as soon as I bought at $65 it headed south. This is why I'm using the 3x leverage to sim a full position though. Not ever knowing which way it will go I wanted to keep some powder dry. So when it got to $45 I added another 200 shares ( that was my first purchase also). That brought my BE to $55. Without going much lower it turned and got back to $55ish where I sold 200. So now I'm in at $55. Well then it continued downward to $32.5 and I bought again(200). From there it got as low as $27. Got me nervous but I was prepared to let it go further and buy again. It got back up to my BE of $43.75 and I sold 200 shares to get me back to a 1/3 acct value position of 200 shares. So here I am at about even and just trying to decide if this is viable or have I just been lucky so far. My plan has been to maintain the 200 shrs or roughly 1/3 acct value while buying again @ 30% pull back and selling when back to even.
