Forex heat maps are visual tools that display the strength or weakness of various currencies in real time. They represent a currency’s movement relative to others, making it easy to identify which currencies are performing well and which are underperforming. Forex heat maps are valuable for gauging market sentiment, as they provide insights into the prevailing risk-on or risk-off sentiment in the forex market.

Heat maps allow traders to quickly assess the market’s mood by visualising the strength of currency pairs. In this guide, we’ll explore how forex heat maps work and how you can use them to gain insights into sentiment and make more informed trading decisions.

What Are Forex Heat Maps?

A forex heat map is a graphical representation of currency pair performance, typically showing the percentage change in price over a specific time period (e.g., 1 hour, 1 day). The map is colour-coded, with each currency pair represented by a cell that is shaded based on its price movement:

• Green indicates a currency is strengthening.
• Red indicates a currency is weakening.
• Yellow or neutral colours show little to no change in price.

By observing the heat map, traders can quickly identify which currencies are gaining or losing value, and how different currencies are performing relative to one another.

How Forex Heat Maps Reflect Market Sentiment

1. Risk-On Sentiment (Bullish Market):
   • In a risk-on environment, market participants are willing to take on more risk and often move capital into higher-yielding, riskier assets, such as commodity-linked currencies (AUD, NZD, CAD) or emerging market currencies.
   • On a forex heat map, you will see these currencies represented in green or showing strong upward movement, indicating that investors are optimistic and confident in the global economy.
   • Example: If the AUD and NZD are showing strong positive movements on the heat map, it suggests that investors are in a risk-on mood, willing to buy assets linked to global growth, like commodities or higher-yielding currencies.
2. Risk-Off Sentiment (Bearish Market):
   • In a risk-off environment, traders become more risk-averse, seeking safety in stable, low-yielding currencies such as the US dollar (USD), Japanese yen (JPY), and Swiss franc (CHF). These currencies tend to perform well when there is economic uncertainty or geopolitical instability.
   • On a forex heat map, you will see these safe-haven currencies in green or showing upward movement, indicating that investors are flocking to them as a safe store of value.
   • Example: If the USD or JPY are showing significant gains in a forex heat map, it could indicate that market sentiment is risk-off, with traders moving away from riskier currencies and into safer options due to uncertainty or crisis conditions.
3. Currency Divergence and Market Sentiment:
   • Forex heat maps can highlight divergence in currency performance, where certain currencies are moving in one direction while others move in the opposite. This can give insights into how strong or weak market sentiment is towards particular regions or economies.
   • For example, if major European currencies (EUR, GBP) are weakening, while the USD is strengthening, this could indicate that investors are more optimistic about the U.S. economy or concerned about economic conditions in Europe.

How to Use Forex Heat Maps for Sentiment Analysis

1. Identify Strong and Weak Currencies:
   • Look at which currencies are showing the most significant gains (green) and losses (red) in the heat map. This gives you a sense of market sentiment, whether it’s risk-on or risk-off, based on the performance of different currencies.
   • Example: If the AUD is green and strengthening across multiple currency pairs, and the USD is showing weakness (red), it suggests a positive sentiment toward riskier assets and a bearish outlook on the USD.
2. Spot Trends and Momentum:
   • By analyzing how long certain currencies remain in the green or red zones, you can identify trends and momentum. A currency that has been consistently in the green for an extended period suggests strong bullish sentiment, while a currency in the red indicates bearish sentiment.
   • Example: If the NZD has been in the green for several hours, it may indicate that risk-on sentiment is prevailing and that the New Zealand dollar is benefiting from this broader market mood.
3. Watch for Reversals:
   • Sudden shifts in a currency’s colour on the heat map can signal a potential reversal in sentiment. If a currency that has been in the red turns green, it might indicate a shift towards risk-on sentiment for that currency or a broader change in market mood.
   • Example: If the GBP suddenly shifts from red to green, it could be a sign of renewed confidence in the UK economy, possibly following positive economic data or news.
4. Use Heat Maps to Confirm Other Indicators:
   • Use forex heat maps in conjunction with other technical and fundamental indicators. For example, if you see a strong move in the heat map for a particular currency, you can check if there’s a breakout or confirmation from technical indicators (e.g., moving averages, RSI) to support the sentiment.
   • Example: If the heat map shows strength in the EUR and it coincides with an RSI above 50, this could confirm a bullish outlook for EUR/USD.
5. Evaluate Divergence Between Currency Pairs:
   • Look at the performance of different currency pairs relative to each other. A significant divergence can signal a shift in market sentiment. For instance, if the USD is strengthening against many currencies, but the EUR/USD shows weakness (red), this might indicate a stronger dollar sentiment despite general market volatility.
   • Example: If EUR/USD is red while other currencies like GBP/USD are showing green, it suggests a market preference for the USD over the euro, possibly due to news or economic data affecting the eurozone.

Practical Trading Example Using a Forex Heat Map

1. Scenario: Risk-On Sentiment
   • The forex heat map shows the AUD, NZD, and CAD in green (strong performance), while the JPY and CHF are in red (weaker performance).
   • Trade Setup: The heat map suggests that the market is in a risk-on mode, and commodity-linked currencies are benefiting from investor optimism. A trader might consider buying AUD/USD, NZD/USD, or CAD/USD, anticipating that these currencies will continue to appreciate as the risk appetite increases.
2. Scenario: Risk-Off Sentiment
   • The heat map shows the USD, JPY, and CHF in green (strengthening), while the AUD, NZD, and BRL are in red (weakening).
   • Trade Setup: The heat map signals a risk-off environment, and the trader may look to buy USD/JPY or USD/CHF, or sell AUD/USD, NZD/USD, or EUR/USD, expecting safe-haven currencies to appreciate while riskier currencies weaken.
