Money Management is the key with leveraged trading. Only trade a tiny portion of you balance so that the maximum loss you have only any one trade is 1% to 2% of your balance. That way, you would have to have 50 to 100 losing trades in a row to wipe out your account. If you have that many losing trades in a row you should really give it up!

I like trading FX because there is no reason to have an emotional attachment to any particular currency. Unlike holding shares in a company and being tempted to keep holding it as the price falls because they are "just about" to release some huge announcement that will send the price through the roof, with FX you just follow the price action. Sell if it's going down, buy if it's going up.
