Looking at a single pair like EUR/USD only tells you about the relationship between two currencies at once — it can't tell you whether the move was really about euro strength, dollar weakness, or both. Currency strength analysis solves this by comparing each currency against a basket of others, isolating which one is actually driving the market.
How It Works
To measure USD strength, you'd average its performance against EUR, GBP, JPY, CHF, AUD, CAD, and NZD simultaneously, rather than looking at any single pair. If the dollar is rising against all seven, that's genuine broad dollar strength. If it's only rising against the yen but falling against everything else, the real story is yen weakness, not dollar strength.
A Simplified Worked Example
Suppose over one trading day: EUR/USD +0.3%, GBP/USD +0.1%, AUD/USD +0.5%, USD/JPY +0.6%, USD/CHF +0.4%, USD/CAD +0.2%. Converting these into per-currency performance shows the dollar actually gained against JPY and CHF but lost against EUR, GBP, and AUD. The 'dollar is strong today' headline would be misleading — the more accurate read is that JPY and CHF were the weakest currencies, while AUD and EUR were the strongest.
| Currency | Relative performance |
|---|---|
| AUD | Strongest — best performer of the group |
| EUR | Strong |
| GBP | Mildly strong |
| CAD | Roughly neutral |
| USD | Mixed — up vs some, down vs others |
| CHF | Weak |
| JPY | Weakest — worst performer of the group |
Turning Strength Into Trade Ideas
Once you've ranked currencies from strongest to weakest, the highest-conviction trade is usually pairing the strongest currency against the weakest one — in the example above, that would be buying AUD/JPY, since it combines the day's strongest currency with its weakest. This tends to produce cleaner, more decisive trends than pairing two currencies in the middle of the ranking.
Currency strength analysis tells you where the momentum is concentrated, but it doesn't give you entry timing. Combine it with your normal technical setup — use strength ranking to choose which pair to focus on, then apply your usual entry rules.
Practical Tools
- ▸Many charting platforms offer built-in currency strength meters that update in real time.
- ▸You can approximate it manually by checking percentage moves across the seven major pairs.
- ▸Look at multiple timeframes — a currency can be strong intraday but weak on the weekly chart, so match the tool to your trading horizon.
