Margin
A margin account allows an individual to acquire cash (apply for a line of credit, basically) from a representative to buy a venture. The contrast between the measure of the advance and the cost of the protections is known as the margin.
Exchanging on margin can be risky because, in case you're off-base about the bearing in which the stock will go, you can lose huge money. You should regularly keep a base equilibrium in a margin account
Seriously, I don't really have any knowledge on how to trade on stock right now so I don't understand what margin is all about but I'm actually glad that you took time to explain it here and it's very understandable.
