The factors mentioned above can also cause a currency to decline. For example, the currency of a country with low inflation will generally rise because that country's purchasing power is higher relative to other currencies. Even natural disasters such as earthquakes or tsunamis, which put a strain on a nation’s economy, can have a negative impact on a currency.
A forex trading strategy defines a system that a forex trader uses to determine when to buy or sell a currency pair. There are various forex strategies that traders can use including technical analysis or fundamental analysis. A good forex trading strategy allows for a trader to analyse the market and confidently execute trades with sound risk management techniques.
To easily compare the forex strategies on the three criteria, we've laid them out in a bubble chart. On the vertical axis is ‘Risk-Reward Ratio’ with strategies at the top of the graph having higher reward for the risk taken on each trade. Position trading typically is the strategy with the highest risk reward ratio. On the horizontal axis is time investment that represents how much time is required to actively monitor the trades. The strategy that demands the most in terms of your time resource is scalp trading due to the high frequency of trades being placed on a regular basis.
