don't advise this kind of trading it's too easy for the broker to manipulate the price. Many** brokers have special software which piggy backs your trade. The price you see when you enter your trade will be off the actual price as example 10 decimals . what happens now is the broker has 10 points to play with if your trade is in that 10 point window the software will push your trade the other way making you lose the trade. If you complain they tell you you are still in range of the actual price.
** I have a friend that is a software engineer who has designed and installed such software for a good number of BO brokers. He asked me to not disclose who they are. However most traders would know them if I told you. Folks the whole world of binary options trading has far more risk than Forex simply because it's always a yes or no that wins or loses your trade.
