Use a demo account to practice trading until you are confident enough to trade with live account. Other than that, you can choose to trade with brokers which offers you protection. For example, the broker which I am using right now, CWG Markets do offer protection against my trading losses. They offer the Loss Protection Scheme which is specially designed for their customers to protect their customer's trading losses up to 900 US Dollar per month! Of course, terms and conditions apply. So far I am using this broker, there is no problem with it other than there are limited ways to deposit and withdraw money. If you are interested, you can check out their official website for more information.
