Careful with margin bud, you're gambling with someone elses money. Margin should be used by the casual investor if he sees an opportunity and has the money in a bank account to cover the full position but doesnt' have time to transfer it in to make the play. For example if margin was possible or available when we hit 1.40's, I would have used it if I didn't have any funds for a flipping position.

If you have a decent amount of shares (15k minimum) you can keep 10k base and 5k as a flipping position. It can help protect against the swings just be sure to wait for bottoms and a rally before pulling the trigger. You don't want to get caught. I have done really well until my last 3 trades which I got burned at and then got greedy selling them and didn't fill. Now I'm holding them like a dum-dum. Also if you miss a trade or get caught on the wrong side there's nothing wrong with selling for a small loss and having those funds ready to try and catch the bottom again. It's a good stock to do this on as there are so many fluctuations but we're all quite certain the end game is heading north.
