Stop Loss - is one of the most important things a trader can utilize to be able to protect the assets inside their account. 

Whenever you begin trading it’s important that you always put a stop loss on each and every single trade that you jump into in the forex market. The reason being is that you can never guarantee a win inside of the market so after the trade every size goes against you something that you did not anticipate you can risk losing all of your money if you don’t have a protective stop. 

You shouldn't be trading more than 2% of your account balance to be safe.
