No matter what your strategy for trading, the bottom line is that you need to feel comfortable with it. Always spend time testing your strategy out on a demo account. If you are taking a system from another trader, spend time analyzing their trading with the system. If the system you want to use is a technical system that you developed yourself, try backtesting the strategy with a program like metatrader.
Finding a forex strategy is a personal decision. Each trader uses their own discretion when it comes to executing trades. Results may vary between two traders using the same system. Take your time when deciding on trading methods and developing a system. The forex market isn’t going to dissapear, it will still be there when you are ready to commit to live trading. The better you understand the nuances of your trading system and the forex environment, the better your chance for long term success.
