Well, your friendly online stockbrokers one day send you a message that they now allow marginalized trades and you can borrow funds to buy stocks up to your current stock value. For the sake of simplicity we say the value of your stock is still $ 10,000. In other words you can now buy another $ 10,000 stock while your capital input remains $ 10,000. and I think it is the best way to trade merchants who do not invest more money they can get bonuses from forums and they can make the best money for traders they trade with the amount of bonus they can make a lot of money easily
