Strength Over Time

Tutorial / How to Use

How to Read and Use This Tool

The Currency Strength Meter lets you compare, at a glance, how much each of the 8 major currencies is being bought or sold right now, and track how that has changed over time. Whether you are new to FX or an experienced trader, this guide covers everything from the core concepts to chart interpretation and practical trading applications.

1Three Key Terms to Know First

Grasp these three concepts before using the tool and everything else will click into place.

① Currency Strength

An exchange rate is simply the ratio between two currencies. Looking at one currency in isolation tells you nothing about whether it is strong or weak. Currency strength is a score derived by comparing one currency against many others to quantify how much it is net-bought or net-sold across the board.

② Relative Score (Neutralization)

When the whole market moves in one direction — for example a broad USD rally — a simple return figure makes every currency appear to move together. By subtracting the average of all 8 currencies at each point in time, the tool removes that market-wide bias and isolates the pure relative strength between currencies.

③ Cross Currency Pair

A pair that does not involve USD, such as EURJPY or GBPAUD. Combining the strongest currency (buy) with the weakest currency (sell) tends to produce a clear directional trend, making cross pairs a natural target when using this tool.

④ Multi-Timeframe Analysis

The practice of comparing several timeframes to make trading decisions. When the same currency is strong (or weak) on both a short period (24h) and a long period (1M+), the trend is considered more reliable.

2What Can This Tool Do?

Compare 8 Currencies at a Glance

The 8 major currencies are ranked on a neutral, level playing field. See instantly which currencies are being bought and which are being sold.

Track Strength Changes Over Time

Each currency's relative strength is displayed as a line chart. Switch from 24 hours to 1 year to spot shifts in momentum and trend changes.

Discover Trending Pair Candidates

The strongest and weakest currencies are automatically paired and shown as a trending candidate — so you can narrow your focus before opening a price chart.

3How the Strength Score Is Calculated

The tool scores how much each of the 8 major currencies (USD, EUR, JPY, GBP, AUD, NZD, CAD, CHF) has been bought or sold relative to the others during the selected period. Because exchange rates are always quoted as a ratio of two currencies, the tool uses the following three steps to extract each currency's standalone strength.

Convert to USD-Denominated ValueEvery currency is first expressed as its USD value. EURUSD, GBPUSD, AUDUSD and NZDUSD rates are used as-is; USDJPY, USDCHF and USDCAD rates are inverted (1 ÷ rate).

Calculate Return Since Period StartUsing the opening value of the selected period as the baseline (0), the tool calculates how many percent each currency has moved.

Subtract the Average to NeutralizeAt each point in time, the average return of all 8 currencies is subtracted from every individual return. This removes the broad market direction (e.g., a USD-wide rally) and leaves only pure relative strength.

Strength Score = (currency's period return) − (average return of all 8 currencies)

※ The sum of all scores always equals 0.

Positive = stronger than average (net-bought)　Negative = weaker than average (net-sold)

Rates are sourced from 1-minute bars and aggregated into the interval that matches the selected period (24h = 5 min, 1W = 4h, 1M = 1 day, 3M–1Y = 1 week). The chart updates automatically every minute.

4How to Read the Chart

The chart shows the relative strength score of all 8 currencies over time. Each line starts at 0 at the left edge (period start) and shows how much stronger or weaker each currency has become since then.

Chart Element	What It Means
8 colored lines	Each color-coded line represents one currency. All lines start at 0 at the period start (left edge).
Line above zero	Net-bought currency. The higher above zero, the stronger it is relative to the average.
Line below zero	Net-sold currency. The further below zero, the weaker it is relative to the average.
Right-side labels	Current scores ranked from strongest to weakest, so you can instantly see which currency is where.
Legend	Click to show or hide individual currencies. Useful for focusing on just the pairs you care about.
Period buttons	Switch between 24h and 1Y to change both the display period and the aggregation interval.
Strength ranking	Bar chart at the top. Also shows the strongest and weakest currencies and the suggested trend candidate pair.

⚠️ Scores Are Relative ValuesBecause scores represent the difference from the average, they always sum to zero. A positive score means "stronger than average" — not "price will rise." Always confirm price direction on a candlestick chart.

5How to Analyze With This Tool

Reading the combination of currencies and the shape of their lines helps you identify which pairs to focus on and when. Learn these four common patterns.

PATTERN A

Pattern A — High-Trend Pair

How to spot it: One line is far above zero while another is far below (strongest × weakest).

Meaning: The cross pair formed by these two currencies is likely to show a clear directional trend.

Apply: Buy the strongest, sell the weakest — trend-follow (e.g., strongest EUR × weakest JPY → long EURJPY)

PATTERN B

Pattern B — Range-Prone Setup

How to spot it: Two lines intertwine near zero with a small gap between them.

Meaning: Strength is unclear; directional momentum is unlikely to develop.

Apply: Avoid trend trades. Could be a range candidate for mean-reversion strategies.

PATTERN C

Pattern C — Strength Reversal

How to spot it: A previously strong currency turns down while a weak currency turns up; lines cross.

Meaning: A trend reversal or momentum shift is underway.

Apply: The crossover is a signal to close existing trend positions or consider a new direction.

PATTERN D

Pattern D — Short & Long Term Agree

How to spot it: Switch the period buttons — the same currency is strong (or weak) on both a short and a long timeframe.

Meaning: The more timeframes that agree, the higher the confidence in the trend.

Apply: Use currencies that align across timeframes as the basis for entry decisions.

💡 The Golden Rule of AnalysisUse a longer period to determine the trend direction (which currency is strong/weak), then use a shorter period to time your entry. When the short-term and long-term strength agree on direction, signal reliability increases significantly.

6Do's and Don'ts

✔ Use It as a Pair FilterThe tool tells you which currency pairs deserve attention. Always confirm the final entry with a price chart.

✔ Prioritize Strongest × WeakestThe larger the strength gap, the more likely that cross pair will trend. Use the suggested "Trend Candidate" as your starting point.

✔ Confirm Short-Term and Long-Term AgreeSwitch through the period buttons. The more timeframes that show the same strength ranking, the higher the signal confidence.

✔ Combine With Other Research ToolsPair this tool with moving average analysis, RSI, and an economic calendar to understand the context and sustainability of the strength.

✘ Don't Trade on Score AloneScores are relative values. Entering without a price-chart confirmation, risk management, or a clear stop level is dangerous.

✘ Don't Confuse Positive With RisingA positive score means "stronger than the average" — not that the price will go up. Always verify direction on a price chart.

✘ Don't Ignore Economic EventsStrength scores can shift violently around major data releases. Reduce exposure before and immediately after high-impact events.

✘ Don't Judge on a Single TimeframeShort-term strength can be opposite to long-term strength. Always compare multiple periods before making a decision.

7Frequently Asked Questions

What do positive and negative scores mean?

They show how much each currency deviates from the average of all 8. Positive means net-bought relative to the average; negative means net-sold. Because it is a relative measure, all scores always sum to zero.

Why is USD used as the calculation base?

Most major currencies are actively quoted against USD, providing high liquidity and stable price data. All currencies are first expressed as their USD value, then compared. Subtracting the average at the end means USD itself is evaluated fairly alongside all others.

Which timeframe should I use?

It depends on your goal. Day traders typically look at 24h to 1W; swing traders at 1M or longer. Comparing short and long periods to check whether they agree on direction is recommended regardless of style.

Can I win just by using this tool?

No. This is a supplementary tool for narrowing down which pairs to focus on. Actual entries require price chart analysis, support/resistance levels, stop-loss placement, and risk management (e.g., risking 1–2% of account per trade).

How often is the data updated?

Every minute automatically. The display aggregates 1-minute bars into the interval for the selected period. Strength can change sharply right after a major data release, so always check the latest reading.

8Glossary (Mini FX Dictionary)

Currency Strength: A numeric measure of how much one currency is net-bought or net-sold compared with many other currencies.
Relative Score (Neutralization): The pure strength indicator after subtracting the average of all currencies, removing broad market direction. Scores always sum to zero.
Cross Currency Pair: A pair that excludes USD, e.g. EURJPY. The strongest × weakest combination tends to trend well.
Trend Following (Long-Bias): Trading in the direction of the trend: buying the strong currency and selling the weak one. The primary use-case for this tool.
Mean Reversion (Counter-Trend): Trading against the trend. Used in range-bound markets; higher difficulty level.
Multi-Timeframe Analysis: Comparing multiple periods to make decisions. When strength direction agrees across timeframes, signal reliability is higher.
Momentum: The speed of price movement. A steeper line on the chart indicates stronger buy or sell momentum.
Stop-Loss (Stop Out): Closing a position once a defined loss level is reached. Essential risk management for every trade.
