No continuation or reversal forecast
A signed change or relative rank describes the displayed dates only. The page does not test whether the movement will persist, reverse or produce a profitable trade.
Forex Currency Heatmap
Compare 28 major and cross-pair relationships across five calendar lookbacks using dated ECB reference observations. Switch between conventional pair cards and an 8 × 8 directed matrix; signed values and direction symbols keep meaning independent of color.

What is a forex currency heatmap?
A forex currency heatmap compares signed pair movement across a group of currencies for one selected period. This daily-reference version derives 28 conventional relationships and 56 directed matrix cells from two displayed ECB observation dates. Higher and lower describe historical cross-rate change only—not a forecast, signal or broker quote.
Signed changeLater cross rate versus earlier cross rate
Text directionHigher, little changed or lower
Relative scoreSeparate eight-currency model output
Source and observation context
Frankfurter v2 supplies direct EUR-based reference rows attributed to the ECB. The governed source adapter re-bases those rows into USD reference legs, and the pair model derives internally consistent crosses for USD, EUR, GBP, JPY, AUD, NZD, CAD and CHF. Every active result identifies the actual dates returned.
Daily reference observations, not live broker pricesThe derived crosses are modified analytical data. They do not include executable quotes, intraday ticks, spreads, swaps, slippage or broker-specific symbol specifications.
How to use this view
- 1Choose one calendar lookback
Select 1D, 1W, 1M, 3M or YTD. The source returns its available earlier and later daily observation dates.
- 2Read text and number together
Use the arrow, direction label and signed percentage. Color reinforces the band but does not carry the meaning alone.
- 3Filter, sort and inspect
Filter by a currency or major pairs, then open any card for the exact earlier rate, later rate and dates.

The matrix contains 56 directed cells but only 28 reciprocal currency relationships. Reversing a pair changes its orientation and percentage arithmetic; it does not create an independent market.

Worked example from the verification fixture
This is a fixed model test, not current market data. It uses complete earlier and later USD reference-leg sets so every displayed pair number can be regenerated by currency_pair_heatmap 1.0.0.
| Pair | Signed change | Displayed interpretation |
|---|---|---|
| EUR/USD | -1.149% | Lower, strong negative band |
| GBP/USD | +0.680% | Higher |
| USD/JPY | +1.014% | Higher, strong positive band |
| AUD/USD | +1.342% | Higher, strong positive band |
EUR/USD at -1.149% means one euro bought 1.149% fewer US dollars at the later fixture observation. It does not label EUR bearish, predict the next move or account for a broker’s bid, ask or spread.
Method and settings
Model currency_pair_heatmap 1.0.0 derives all 56 directed crosses from two complete USD reference sets, then calculates the signed percentage change. The 28 cards select conventional orientations from that matrix. Currency rankings come from a separate model that averages seven directed comparisons per currency and min-max normalizes the eight averages.
pair change = (later derived cross - earlier derived cross) / earlier derived cross × 100
relative currency score = min-max normalization of seven directed changes
relative currency score = min-max normalization of seven directed changes
- Pair directions: a fixed list of 28 conventional major and cross-pair orientations.
- Bands: product display bands applied to the observed percentage only; each includes an arrow and text label.
- Filtering: changes what is displayed, not what enters the eight-currency model.
- Missing data: the result is withheld when a required source leg or observation date is absent.
Currency heatmap vs strength meter vs volatility heatmap
| Tool | What it compares | Use it to answer |
|---|---|---|
| Currency heatmap | Signed cross-rate changes between two daily observations | Which conventional pairs moved higher or lower over the selected calendar window? |
| Currency strength meter | Each currency's average against the other seven, normalized within one sample | How did each currency rank relative to this eight-currency group? |
| Volatility heatmap | Close-derived range proxies across pairs | Which pairs showed larger or smaller historical movement magnitude? |
Sources and calculation references
Both views request ECB-attributed daily reference rates through Frankfurter v2. Cross rates, percentage changes and relative scores are derived analytical outputs; they are not published by the ECB as trading signals.
- European Central Bank euro reference exchange rates — official publication context and reference-rate limitations.
- Frankfurter v2 documentation — API parameters and ECB provider attribution used by the adapter.
Interpretation boundaries
No intraday market state
Refreshing does not manufacture a new ECB observation. Weekend and holiday requests can return the same available business-day date.
No execution or sizing output
Broker pips, spreads, position size, liquidity and execution costs require broker-specific quotes and separately governed tools.
Frequently asked questions
- It shows the signed percentage change of 28 conventional forex pair directions between two displayed daily ECB reference-rate observation dates. Each card also includes a text direction label.
- The adapter derives each cross rate from a complete USD reference set, then calculates (later rate - earlier rate) / earlier rate × 100 for the selected calendar lookback.
- Yes. Every card and legend item includes an up, down or approximately-equal symbol, a Higher, Lower or Little changed text label, and the signed percentage value.
- No. It uses daily ECB reference-rate observations supplied through Frankfurter. The derived crosses are modified analytical data, not intraday ticks or executable broker quotes.
- Model 1.0.0 averages seven directed percentage changes for each currency, then min-max normalizes the eight averages to 0–100. The score is relative within that sample.
- No. The cards, filters, ordering and currency scores are descriptive. They do not provide forecasts, entries, exits, position sizes or pair-selection recommendations.
- Blue bands reinforce positive historical change, orange bands reinforce negative change, and grey marks little change between -0.30% and +0.30%. Every result also includes a sign, symbol and text label, so color is not required.
- The lookback selects a calendar target, but ECB reference observations are not published every calendar day. Frankfurter can return the previous available observation for weekends, holidays or TARGET closing days, and the page displays the actual returned dates.
