Just like stocks, you can trade currencies based on what you think about its value (or where it goes). But the big difference with forex is that you can trade up or down just as easily. If you think that the currency will grow in value, you can buy it. If you think it will decrease, you can sell it. With such a large market, finding a buyer when you sell and a seller when you buy is much easier than in other markets. You may have heard in the news that China devalues its currency in order to attract more foreign business to its country. If you think that this trend will continue, you can make a deal in the Forex market by selling Chinese currency for another currency, say, the US dollar. The more the Chinese currency depreciates against the US dollar, the higher your profit. If the Chinese currency rises in price when you have a sell position, your losses grow and you want to exit the trade.

In practical terms, this manifests itself in traders holding losing positions open for too long, simply because they fail to consider the options that are outside of their comfort zone. You must not be afraid of trying new things when trading Forex - be willing to try new strategies, and go against what you know. By anchoring yourself to outdated strategies and knowledge, you're only increasing the probability of bigger losses.
This is the only way you can really stay on top of your trading. Allow yourself to make mistakes - and don't make the mistake of being scared to prove yourself wrong - you'll be in a much better position for it in the long run. You have to be comfortable with accepting that mistakes are inevitable, especially in the early stages. It's all part of the learning curve.
