Currency indices for dummies

Currency indices, in simple words, are a general metric of the currency of a certain country without reference to the exchange rate. In a more complicated sense – the total ratio of the currency to a basket of other leading world currencies.

In the forex market, in addition to observing and trading certain pairs, many experienced traders use indices as additional analysis tools. In particular, the dollar index (DXY). Indices can act as guides or as filters. Such strategies are quite rare, and are mainly used for high-speed trading on short timeframes, when the slightest change in indicators can be a signal for a deal.

As filters, indices are used for longer-term trades, when the trend of a currency pair can be controversial. By considering the quote currency, you can use its index to understand the strength relative to others and understand the sentiments of large players regarding it.

Another popular use of index derivatives is futures when trading volume based strategies. Futures for currency indices traded on the Chicago Stock Exchange (CME) are analyzed by volume, from which traders draw conclusions regarding the levels or zones of accumulation of market activity. When compared to pairs, these places often coincide or completely overlap each other, which makes it easier to understand the structure and direction of a trend or sideways movement.

Indices also typically reflect real changes in currency strength when news releases. For example, the result of the US unemployment report will be easier and more correct to track on the index, and not on EUR/USD or another pair with the dollar. Yes, the change will also be reflected in the pairs, but the correlation with the news factors of other countries will also affect this one. Therefore, the index will show a more accurate impact. It is much easier to open the economic calendar, check the aggregate news, and mark these moments on the index chart, rather than on each pair, in order to have a complete picture of events. After that, the upcoming news will be applicable already for pairs for planning transactions based on the results and expectations of reactions, which are easy to study by indices.
