Using Currency Strength to Filter Forex Pairs for Trends and Ranges
Summary
The Currency Strength Index (CSI) compares the relative momentum of eight major currencies by mathematically decorrelating 28 currency pairs. It uses percentage differences in linearly weighted averages of closing prices to help distinguish whether a pair’s movement reflects strength in one currency or weakness in the other. The indicator displays the currency readings on a chart and is described as independent of which pair’s chart hosts it.
The article suggests comparing currencies: those diverging may offer trend-following candidates, while currencies moving in parallel may be range-bound and suitable for channel-based analysis. Multiple timeframes can add context. CSI is presented as a filter for selecting pairs and monitoring possible shifts in relative strength; it does not provide trade entry timing. The document offers no tests or quantified results, and its suggestions are general ideas rather than a complete trading system. Users would need separate rules for entries, exits, and risk management.
Key ideas
- CSI estimates the relative strength of eight major currencies from 28 cross pairs.
- Its calculation uses percentage differences in linearly weighted average closing prices.
- Diverging currency readings can help identify potential trend pairs, while parallel readings may suggest range conditions.
- The indicator filters pairs and provides context but does not specify trade entries or validate performance.
