The single most-underused edge in retail forex: trading the strongest currency against the weakest. This free currency strength meter (also known as a currency strength heat map) ranks USD, EUR, GBP, JPY, AUD, NZD, CAD, CHF, and XAU by intraday % change, colour-codes each row from deep green (strong) to deep red (weak), and auto-suggests the highest-conviction forex pair to trade right now.
Currency Strength Meter is part of the free Aurex Trader calculator suite — 23 browser-based tools for gold (XAUUSD) and forex traders. Nothing is installed, no account is required, and every calculation runs locally in your browser.

A currency strength meter measures how strong or weak each individual currency is against a basket of others over a chosen timeframe. It's more useful than looking at pairs alone because it isolates which currency is actually driving a pair's move.
The core principle: buy the strongest currency and sell the weakest. If USD is at +0.6% and JPY is at −0.5%, USDJPY is the highest-conviction pair to buy. If XAU is +0.8% and USD is −0.3%, XAUUSD long has strong tailwinds.
Because gold acts as a currency — the anti-USD. Ranking XAU alongside USD, EUR, JPY gives you a full picture of risk-on vs risk-off flow. When XAU is #1 strongest and USD is #8 weakest, XAUUSD is usually running trend.
Once at each session change — morning check (London open, 12 PM PKT), afternoon check (NY open, 6 PM PKT), and evening check (before you place any late-session trades). Strength can flip inside a session on high-impact news.
Yes — strength ranks currencies individually, correlation measures how pairs move together. Use both: strength picks the trade, correlation stops you from stacking three trades that are really the same bet.
