Trading successfully is by no means a simple matter. It requires time, market knowledge and market understanding and a large amount of self restraint. Anyone who says you can consistently make money in foreign exchange markets is being untruthful. Foreign exchange by nature, is a volatile market. The practice of trading it by way of margin increases that volatility exponentially. We are therefore talking about a very 'fast market' which is naturally inconsistent. Following that precept, it is logical to say that in order to make a successful trade, a trader has to take into account technical and fundamental data and make an informed decision based on his perception of market sentiment and market expectation. Timing a trade correctly is probably the most important variable in trading successfully but invariably there will be times where a traders' timing will be off. Don't loose heart if you loose on some trades. Experienced and seasoned traders do not expect to generate returns on every trade. Let's enumerate what a trader needs to do in order to put the best chances for profitable trades on his side:Trade with money you can afford to lose: Trading forex markets is speculative and can result in loss, it is also exciting, exhilarating and can be addictive. The more you are 'involved with your money' the harder it is to make a clear-headed decision. Money you have earned is precious, but money you need to survive should never be traded.If in doubt, stay out: If you're unsure about a trade and find you're hesitating, stay on the sidelines.Trade logical transaction sizes: Margin trading allows the forex trader a very large amount of leverage, trading at full margin capacity can make for some very large profits or losses on an account. Scaling your trades so that you may re-enter the market or make transactions on other currencies is generally wiser. In short, don't trade amounts that can potentially wipe you out and don't put all your eggs in one basket.
