Currency markets are important to a broad range of participants, from banks, brokers, hedge funds and investor traders who trade FX. Any company that operates or has customers overseas will need to trade currency. Central banks can also be active in currency markets, as they seek to keep the currency they are responsible for trading within a specific range.
Like most technical strategies, identifying the trend is step 1. Many scalpers use indicators such as the moving average to verify the trend. Using these key levels of the trend on longer time frames allows the trader to see the bigger picture. These levels will create support and resistance bands. Scalping within this band can then be attempted on smaller time frames using oscillators such as the RSI. Stops are placed a few pips away to avoid large movements against the trade. The MACD indicator is another useful tool that can be exercised by the trader to enter/exit trades.
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.
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.
