In my opinion there is no such thing as a best Forex trading strategy. There is no one size fits all. Determining what the best Forex trading strategy for you is depends on several factors and conditions, such as:
What is your risk tolerance?
What are your financial objectives?
What is your personal philosophy about money?
How much time can you personally devote to trading the forex markets?
Are you looking for quick profits, or are you taking a longer term approach?
There are potential advantages and disadvantages to different trading strategies. Some people take a strictly mathematical approach to the market, trying to predict where it is likely to go over a set time in the future. This may be for a few minutes, an hour, a day, a week, a month, or longer. A word of caution here if you are thinking more in terms of long periods of time, such as weeks or months…keep in mind that the Forex market is not so much like investing in the stock market in this regard. As a rule of thumb, with stock trading the objective is to find one or more stocks that look promising based on several factors with the goal in mind that you will stick with that stock until the company has had time to grow, thus making your stock more valuable as time goes by. Trading in currencies is, in my opinion, an entirely different type of financial vehicle. Some people may not even think of it as an investment, but a more speculative type of transaction. Some people think trading currencies is like rolling the dice or pulling the lever, a pure random chance. I do not personally think of trading Forex in these terms. It can certainly be an investment, if treated like one, and while it operates in a different financial realm than stock trading, it can certainly be a vehicle that can help you achieve some financial goals.
