Constructing Forex Currency Baskets and Unified Strength Indicators
Summary
The article groups the 28 major currency pairs into eight baskets according to a shared base or quote currency. It explains how buying a currency basket translates into opposite trade directions across pairs where that currency appears on different sides. The basket's status can be summarized with a unified indicator, intended to isolate common currency behavior from the differences between individual exchange rates.
As a construction example, the article applies an unweighted geometric mean to appropriately oriented exchange rates, drawing on the logic of a currency index. It proposes adapting standard tools such as RSI and Stochastic to represent basket-level overbought or oversold conditions, and discusses using those readings to forecast pair behavior, filter entries, and look for divergences. The examples illustrate similarity among RSI readings for several GBP pairs and compare a computed USD basket with an existing index. The method is introductory: it offers no validated trading results, assumes meaningful common behavior within each basket, and recommends combining these indicators with other signals rather than treating them as replacements for conventional analysis.
Key ideas
- Currency pairs can be grouped into baskets according to a currency shared as the base or quote.
- Buying a basket currency requires reversing trade direction on pairs where that currency is quoted second.
- An unweighted geometric mean of oriented exchange rates can provide a synthetic basket series.
- Unified RSI or Stochastic readings aim to represent a currency's shared status across its pairs.
- Basket indicators may support filters and divergence analysis, but the article presents no validated performance evidence.
