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.

Identify the state of the market:
What is the market doing? Is it trending upwards, downwards, is it in a trading range. Is the trend strong or weak, did it begin long ago or does it look like a new trend that's forming. Getting a clear picture of the market situation is laying the groundwork for a successful trade.

Gauge market sentiment:
Market sentiment is what most of the market is perceived to be feeling about the market and therefore what it is doing or will do. This is basically about trend. You may have heard the term 'the trend is your friend', this basically means that if you're in the right direction with a strong trend you will make successful trades. This of course is very simplistic, a trend is capable of reversal at any time. Technical and fundamental data can indicate however if the trend has begun long ago and if it is strong or weak.

Market expectation:
Market expection relates to what most people are expecting as far as upcoming news is concerned. If people are expecting an interest rate to rise and it does, then there usually will not be much of a movement because the information will already have been 'discounted' by the market, alternatively if the adverse happens, markets will usually react violently.

Use what other traders use:
In a perfect world, every trader would be looking at a 14 day RSI and making trading decisions based on that. If that was the case, when RSI would go under the 30 level, everyone would buy and by consequence the price would rise. Needless to say, the world is not perfect and not all market participants follow the same technical indicators, draw the same trendlines and identify the same support & resistance levels. The great diversity of opinions and techniques used translates directly into price diversity. Traders however have a tendency to use a limited variety of technical tools. The most common are 9 and 14 day RSI, obvious trendlines and support levels, fibonnacci retracement, MACD and 9, 20 & 40 day exponential moving averages. The closer you get to what most traders are looking at, the more precise your estimations will be. The reason for this is simple arithmetic, larger numbers of buyers than sellers at a certain price will move the market up from that price and vice-versa.
