The primary rule of this trading is to have patience and never lose hope. Mostly people tell me that they lost a lot of money while trading and they want to recover it now. So, personally I will advise you to start with low investment and even if you are a pro, when the graph is not stable invest less amount. Besides, everything has two faces and same is true for this trading, you can earn easily but at thee same time you can lose easily as well. But when you lose something, you can recover it in the same day and earn even more. Here is my one day trading where I invest in unstable graph but later through patience and small investment again and again I not only recovered the loss but also earned profit.
