How to trade the US Dollar Index

14 March 2023 By Mark Nguyen


The US Dollar Index (DXY) is a popular tool used by forex traders to assess the value of the US dollar relative to a basket of other major currencies. The DXY is calculated using the weighted average of six major currencies: the euro, yen, pound sterling, Canadian dollar, Swedish krona, and Swiss franc.

To use the DXY to trade forex, you can follow these steps:

1. Monitor the DXY:
Keep an eye on the movements of the DXY to get a sense of the overall strength or weakness of the US dollar. You can use technical analysis tools, such as moving averages or trend lines, to identify the direction of the trend.
2. Analyse currency pairs
Look for forex pairs that are inversely correlated to the DXY. This means that when the DXY goes up, the currency pair goes down, and vice versa. For example, the EUR/USD pair is negatively correlated to the DXY, which means that as the DXY goes up, the EUR/USD pair goes down.


  1. Plan your trades

Once you have identified a currency pair that is inversely correlated to the DXY, you can plan your trades accordingly. For example, if the DXY is showing signs of weakness, you may want to consider going long on a negatively correlated currency pair, such as the EUR/USD.

  1. Manage your risk

As with any trading strategy, it’s important to manage your risk when using the DXY to trade forex. Make sure to use stop-loss orders to limit your losses in case the market moves against you.

Currency pairs may be influenced by other factors besides the DXY, which may not be a perfect indicator of the US dollar’s value. To make informed trading decisions, it is important to combine the DXY with other technical and fundamental analysis tools.
