People trade the forex markets using various different time frames. Some traders like to scalp the markets using the 1 minute or the 5 minute chart, whilst others prefer to take positions on the daily or weekly chart, for instance. However it's generally the longer term traders who turn out to be more successful traders in the long run, so with that in mind I want to discuss two technical indicators you can use to help you trade these long-term charts.
The first is the EMA(200). If you're not already familiar with this indicator, it's basically the 200 day exponential moving average. Many people who trade the daily charts apply the EMA(200) to their chart because it gives you an impression of the long-term trend.
If it is sloping upwards then the price is clearly in an upwards trend, and therefore you should be considering opening long position in order to trade with this trend, and if it is sloping downwards, the price is trending downwards and you should only be looking to open short positions.
The second indicator you should consider using is the supertrend indicator. This is not one of the most popular indicators, simply because it's not included with most charting software, however overall it is very effective. Just like the exponential moving average indicator mentioned above, the supertrend indicator is another indicator that will highlight the overall trend, which will therefore help you determine which way you should be trading.
It is basically a line that moves in accordance with the price and changes colour based on the overall trend. If the line is currently green, then the trend is currently upwards, and if it's red then the price is obviously trending downwards. So it's a very simple indicator to use, and overall it's very effective because when the indicator changes colour you will often find that the price will move strongly in the direction of this new trend.
