Every trade involves some level of risk, but as long as you can quantify it, you can manage it. Just keep in mind that risk can be magnified by using too much leverage on your trading capital, as well as by a lack of liquidity in the market. Taking some risk is the only way to generate good returns with a disciplined approach and good trading habits.
The first rule of risk management is to calculate the chances of your trade succeeding. To do so, you must understand both fundamental and technical analysis. You'll need to understand the dynamics of the market you're trading in, as well as where the likely psychological price trigger points are, which a price chart can help you determine.
As you can see, forex money management is as adaptable and diverse as the market itself. The only universal rule is that to succeed, all traders in this market must practice some form of it.
There are two approaches to successful money management. A trader can choose to take frequent small stops and try to profit from the few large winning trades, or he can choose to go for many small squirrel-like gains and take infrequent but large stops in the hope that the many small profits will outweigh the few large losses.
