I think if you want to trade margin then you should have to know about how to be able to do the right margin in order to avoid losses because there are so many new traders who are doing the wrong step.
That is the common mistake many beginners do due to over enthusiasm. When availability of more easy capital in front of you will lead to disasters most of the times rather than enabling you to think over on how to make use of them along with your research and analysis. In summary, margin will turn you greedy if you have not prepared yourself enough.
Instead of talking about the margins there is a possibility of earning some great profits.
Why would anyone go leveraging when they can simply just invest in the market normally without the fear of completely losing their funds. Margin trading can bring great opportunities when it comes to shorting and longing in the market, but at the same time, the risk is too huge and you really do not want to be going this way if you do not have a very solid trading knowledge. The same way you can end up gaining a lot from it, is the same way you can end up losing everything.
