Trading binary options allows a trader the access to great potential returns and we are talking about above 70% return offered by the majority of brokers. That makes it easier for the trader to be successful as basically one should not be right all the time, a standard rate of 65%-70% of winning trades should be enough for the account to grow.
Trading with Binary Options Ultimatum system offers a good possibility for that outcome to be reached if all the conditions are respected.
The recommendation is to trade only the hourly chart for the currency pairs and to have end of day expiration dates if the time element allows the trade to be taken. However, there are different types of traders and the ones that are less risk-averse may decide to take the signals even if the time element is not in their favor. That would lower the success rate for sure.
