There are several instruments available to you when you start trading with binary options. The simplest of them are the call and put trades. The call and put trades are very simple as they require you decide whether the concerned asset will move up or down. Traders who are new to binary options start with these and gradually as they gain experience, they move on to one touch binary trading.
One touch binary trade requires you to decide whether the price of the concerned asset will touch a certain point or not. This chosen point can be above or below the starting point. If your trade reaches the determined point before the trade time expires, then the trade is closed even if the price changes after that and its time for payout.
