Hello, As the title says, I'd like to learn how. More specifically I'd like to learn how without losing the shirt off my back in the learning process. I am in Canada and I'm guessing most of you are in the US. Anyhow, I am in the process of trying to pick an online brokerage to sign up with ($4.95 per trade). It has low fees however offers only 'margin accounts'. I'm kinda nervous of that word margin. I only want to lose the money I have invested in the brokerage account, not money that I don't have. So how do I get around this? I'm scared I might unknowingly put in an order (as I'm still a beginner) only to find out the next day I'm on the hook for $100K in losses !! I'd like to buy US stocks. From what I gather, when I place an order for a US stock, they convert the CND money in my account on margin to US dollars and buy that stock. Is that what margin is for? How do I pay that margin asap as I hear its loaned to me at 7%. It already sounds like a hell of a hassel. I have more questions about how to buy bonds of overseas corporations that pay an interest (something I'd like to do but I'm clueless as to how its done via an online broker). I'll save that for later. Thank you and this is my first post!
