The Forex Currency Index is an indicator that can be integrated with any forex trading system or strategy for additional validation of trade entries or exits.
What is the Currency Index indicator?
The currency index is a measure of how one currency is changing in relation to all other foreign currencies. It is computed by averaging the changes in one currency compared to the others. This data is presented in a graphical format, making it easy to see the trends of each individual currency. The index is based on an arithmetic average of changes in each currency pair.
Currency Index Strategy
Buy Signal
- When the currency index indicator shows a currency is undervalued compared to other currencies in the basket, it may be a good time to buy that currency.
- When the currency index indicator is trending upward for a specific currency, it may indicate that the currency is gaining strength and could potentially be a good time to buy.

Sell Signal
- Selling a currency may be a good option when the currency index indicator indicates that it is overvalued compared to other currencies in the basket.
- If the currency index indicator is trending downward for a specific currency, it may signify that the currency is becoming weaker and could be a good time to sell.

Currency Index Indicator Pros & Cons
Pros
- Can provide a broad perspective on the overall strength or weakness of a currency.
- Can be useful for identifying long-term trends in the currency market.
- Can help traders make decisions about diversifying their portfolio among different currencies.
Cons
- May not provide a detailed enough picture for short-term trades or for trading in specific currency pairs.
- Does not take into account factors that can affect individual currency pairs, such as interest rate differentials or political developments.
- Can be affected by the weighting and construction of the index.
The way the currencies are selected and how much they weigh in the index, along with the exchange rates used to calculate it, is referred to:
Basket Composition & Parity.
A currency index is a tool used in forex trading to measure the relative strength or weakness of a currency in relation to a basket of other currencies. The composition of this basket is carefully chosen to include the currency in question, as well as all other major currencies. The basket is constructed in such a way that each currency pair included, it contains the currency in question either as the base or quote component includes all 8 major currencies and for pairs in which the currency in question is the quote component, the parity of the pair is reversed to adjust for relative strength.
For example:
The basket used to calculate the EUR currency index would include currency pairs such as EUR/USD, EUR/GBP, EUR/AUD, and so on, with each pair having EUR as the base component and a parity of +1.
This method of calculating the currency index is unique in that it uses an equally weighted portfolio of currencies instead of a weighted portfolio that takes into account economic factors. This helps to remove any bias from the calculation.
Conclusion
The currency index indicator is a useful instrument for forex traders as it gives them an idea of the relative strength or weakness of various currencies. By comparing the performance of a given currency with a group of other currencies, traders can detect patterns and make knowledgeable choices about when to enter or exit a trade.
