What is Market Sentiment in Forex, and How It is Used in Trading
In this overview, I will get you acquainted with such a notion as market sentiment in Forex. It helps confirm the current trend and warns you of its probable end.
What is market sentiment?
The market sentiment means the prevailing mood of most market participants at a certain moment. The word “sentiment” is of French origin and means “feeling, mood”. Market sentiment shows what market participants are currently keen on – buying a financial instrument (a group of assets) or selling it.
In other words, market sentiment is the current balance of traders’, investors’, and other market players’ optimism and pessimism about a certain financial market or asset. This is some sort of collective emotion based on certain expectations. The expectations are formed, as a rule, by the news and various fundamental factors.
For example, if market participants are sure that the stock market will be growing, they start buying shares actively and thus support the bullish trend. On the contrary, if most players are sure that the stock price will be falling, and a bearish trend will appear – they will start selling assets that they expect to decline soon. As a result, market supply will become excessive, making the price drop.
Forex market sentiment shows what most market participants prefer to do now: buy or sell currencies. Traders use such expressions as “buy bucks” — this means traders are ready to buy the USD against other currencies, or “sell bucks” — which means traders are ready to sell the USD against other currencies.
Market sentiment and expectations are influenced by several factors. Factors that support the currency rate form positive sentiment (moods to buy). Factors that drive the currency down form negative market sentiment (moods to sell). Check below the factors that influence Forex market sentiment.
What factors influence Forex market sentiment?
Market sentiment is mostly influenced by so-called fundamental factors. They include various financial, economic, and political events that influence directly currency rates. Such factors are studied by fundamental analysis. Here are the most important of such factors:
- Monetary policy of Central banks: cycles of increasing and decreasing the main interest rate can form long-term uptrends and downtrends in the national currency. If market players expect the rate to grow, the market sentiment will be bullish: market players will be ready to buy. If a decrease in the interest rate is expected, things go vice versa.
- Economic factors: if the news about the country’s economy is positive (GDP, employment, production, etc.), market sentiment about the currency improves.
- Political factors: elections, government resignations, scandals, sanctions, etc. can form negative market sentiment towards a currency.
- Rumors and expectations: they include political and economic factors but in the form of rumors and expectations.
- Force majeure: natural disasters, man-made disasters, terror acts, epidemics. All this can form serious negative sentiment towards a currency.
The influence of fundamental factors on Forex market sentiment can be short-term (several minutes to several days) or long-term (several weeks, months, years). For example, information about the growth of unemployment last month can have a short-term negative effect on market sentiment, while an announcement of the CB head about the necessity to increase interest rates can form a long-term positive sentiment to a currency.
Indicators for assessing Forex market sentiment
To detect the current market sentiment, various indicators can be used. They try to evaluate market sentiment and express it in digits or graphically. By them, one can conclude on the current positions and opinions of traders and how they can influence price moves.
Here are three popular indicators for assessing Forex sentiment.
The DXY (US dollar index) is the main index that shows the current market sentiment towards the leading world’s currency. The direction in which the index goes (the current trend) reflects the actual market balance. The growth of the index means positive market sentiment and the growth of the USD against major currencies, while the decline of the index means negative sentiment and weakening of the major currency.
The DXY is traded in exchanges as futures and options. By tech analysis, you can analyze the chart of the index and detect the current sentiment towards the USD: positive, negative, or neutral. You can find the DXY chart on various informational resources such as tradingview.com.

COT reports on currency futures
A COT (Commitments of Traders) report is a weekly publication showing aggregate positions of various players of futures markets. The COT is published every Friday by the US CFTC. Though this data refers to futures, they correlate strongly with the Forex market.
COT show clean long and short positions in futures on currencies (and other assets) of three groups of traders:
- Commercial Hedgers are large companies and entities that use the futures market to hedge their risks in the currency and spot markets. They influence the general sentiment moderately.
- Large Traders are major institutional investors, hedge funds, and other organizations trading in the futures market in order to invest and make profits. The sentiment of this group is more important.
- Small Traders: most of this category consists of private market players or small companies. Their influence on the market is scarce.
You can track the market sentiment of currency futures by the COT on various analytical resources, such as finviz.com. Under the charts of currency futures, you can find a diagram where the three groups of traders enumerated above are represented by three lines. When the lines are positive, buying positions prevail, while when the lines are in the negative area, this means selling positions dominate.
COT reports — JPY futures
Another popular and demonstrative instrument for assessing the sentiment is the Moving Averages. They show the average value of the chosen currency pair in a certain period. If the price rises above the average, this means the current sentiment is positive; if it drops below the average, the sentiment is negative.
To assess short-term sentiment, use the MA with a short period (from 5 to 50), for long-term sentiments – the MA with a larger period (100, 200). For example, when the price crosses the 200-days SMA from below, this means the sentiment is becoming positive, and an uptrend might be starting. And vice versa, if the quotations drop below the 200-days SMA, this means negative sentiment and promises a downtrend.

Using Forex sentiment in trading
I would single out systems of using market sentiment in trading. The first strategy presumes using the sentiment for confirming the current market trend, i.e. it helps you choose the main direction n which you will trade. The second strategy presumes the use of signals for the end of the current trend and the beginning of a correction or even a reversal.
Confirming the current trend
You can use the indicators described above. When the indicators are not too close to their extremes, they can help you confirm the current trend:
- The DXY demonstrates an uptrend (positive sentiment towards the dollar) or a downtrend (negative sentiment towards the dollar).
- The diagram based on the COT shows when Large Traders start changing their position: if they go negative, this confirms a downtrend, and if they go positive – an uptrend.
- When the D1 chart crosses the 200-days SMA upwards, this confirms an uptrend, and if it crosses it downwards, this means a downtrend.
- News: positive news supports uptrends, and negative news supports downtrends.
- The chart has risen above the 200-days SMA.
- The DXY demonstrates an ascending move.
- The COT lines on the JPY futures are not at the extreme, the lines of Large Traders set off downwards (sell the yen against the dollar).
- The news is positive, stock markets are growing – this supports the growth of USD/JPY.
All in all, the indicators of the sentiment support an uptrend in the pair; use tech analysis to find entry points for buying positions.

Signals of possible corrections and reversals
When the indicators reach their extremes, or their signals change for the opposite ones, this warns you of a probable correction or reversal:
- The DXY changes direction; reversal patterns might form.
- The COT diagram demonstrates extremes, the lines of Large Traders and Commercial Hedgers demonstrate a serious divergence.
- The price chart opens quite far away from the 200-days SMA, after which it starts the opposite move, closing faster MAs (such as 7, 14).
- News: positive news provokes a positive correction, and negative do correspondingly.
After a strong ascending impulse on the D1 of USD/JPY, there appeared signals for a possible correction or a reversal downwards:
- The chart of the pair is far away from the 200-days SMA, then crosses the faster MAs (7,14) from above.
- The DXY has reversed downwards.
- The COT lines of the yen futures show the year’s extremes, the lines of Large Traders and Commercial Hedgers have diverged maximally.
- The news is neutral.
The indicators signal that USD/JPY has begun a descending correction. Abstain from buying; you can even use tech analysis to find entry points for short-term sales.

Forex market sentiment reflects the prevailing mood of the currency market. By various indicators, you can assess who is dominating the market – bulls (believing in the growth of the currency) or bears (count on its decline). Forex market sentiment is a useful supplement to the rules of fundamental and technical analysis.
Market Sentiments Meaning, Definition, and Overview
Market sentiments are the driving force that can influence the demand and supply as well as move the price. This is why it can be both bullish and bearish depending on the movement direction. For instance, sentiments can be bearish, if the price falls or bullish when it rises.
To identify and define sentiments, traders utilize an array of technical indicators integrated into the trading platform or framework. Additionally, they can opt for extra tools and forms of analysis that make it possible to refine reliable signals for market entry or exit. If an investor is able to recognize the mood correctly. It will help to get maximum return.
In this article, we will not only define sentiments meaning but also review some of the top indicators traders use to understand them.
What Is Sentiment?
The sentiments meaning corresponds to the investors’ mood or attitude in references to a specific instrument, asset, or security. The term could be described as traders’ feeling about the market tone that also reflects the overall market psychology depending on the price activity and movement.
To make things a bit simpler, when the price goes up, it represents bullish market sentiment. If it falls, it shows a bearish market tone. The key features to consider when defining the sentiments meaning are as follows:
- The term refers to the overall attitude towards a traded asset.
- It can be bearish or bullish depending on the price movement.
- To measure sentiments, traders use specific technical indicators.
Understanding the Market Sentiments Meaning
Also known as “investor sentiment”, is a part of the trading fundamentals. It can influence technical indicators. This is why technical analysts and day traders use it regularly. It makes it possible for them to measure not only short-term movements of the asset price but also profit and potential returns. The results will generally rely on the overall investors’ mood and attitude towards a traded security.
At the same time, sentiments appear to be a helpful tool for so-called contrarian investors. Those are traders who tend to oppose the general market movement. In other words, if the majority of people buy an asset, contrarian traders are very likely to sell it.
Experts are used to describing sentiments as bearish or bullish. The concept is quite simple:
- When bears take control over the market, the stock price goes down.
- When bulls are in charge of the situation, the stock price goes up.
While the financial market is often driven by participants’ emotions, we cannot say that sentiments can fully rely on fundamentals, as they mainly refer to business performance. On the other hand, investors find it possible to identify over and undervalued stocks using sentiments. It can be achieved with the help of different technical (sentiment) indicators.
Market Sentiment Indicators
The following can be used to measure market sentiments and define the overall market mood as well as if it is bearish or bullish:
- VIX – also known under the “fear index” moniker. Used together with moving averages to define if it is low or high.
- High-Low Index – it is used to compare stocks that make 52-week highs and lows. As a rule, the indicator helps to underlie Nasdaq 100, S&P 500, and some other popular indices.
- BPI — Bullish Percent Index can be applied to figure and point charts in an effort to measure the number of bullish stocks. If the reading gives BPI over 80%, the market sentiment looks extremely optimistic. If it falls down below 20%, it means that the market is oversold.
Those are only a few tools to measure sentiments. You may opt for moving averages and some other indicators. Just make sure you apply proper reading and some fundamental knowledge to put all facts together and decide on the next move.

Every trader, starting their trading activity in Forex, strives to increase their level of well-being, which should be facilitated by successful transactions with currency. In this regard, it is important to be able to navigate in such a concept as market sentiment. Understanding how the market works from the inside will certainly help a trader to choose the most effective automated Forex trading strategies. Conversely, the lack of information on this topic can lead to rash and chaotic decisions that carry the risk of loss.
How do you understand what market sentiment is in Forex? First of all, a trader should grasp the essence of this term in a generalized context, after which the knowledge gained can be considered in relation to automated Forex trading. In view of the fact that the definition of market sentiment applies to both the stock and financial markets in aggregate, in our today’s material we will consider the concept of market sentiment, first in the global, general economic sense, and then in relation to currency trading in Forex.
Thus, market sentiment is the opinion that investors form about a security or currency. The significance of such a factor as the market sentiment is extremely high, because the psychological sentiment of a large group of people has a significant impact on the development of various trends in the growth or decrease of prices for trading products. It is generally accepted that when prices abruptly go up, bulls become the main players in the market, and when the dynamics of growth is diminishing, bears dictate their market conditions. Most traders keep questioning themselves: how to practically use the concept of market sentiment to their advantage?
In order to thoroughly study the subject of market sentiment and learn how to apply this information to increase the profitability of automated trading in Forex, below we will turn to the topic of the sentiment of the participants in a particular market, since here the preconditions from which a certain market sentiment can play a key role. Having learned to understand both the psycho-emotional and the economic components of these processes, you will be able to more rationally and predictably plan the execution of transactions with currency in Forex.
How to interpret the sentiment of participants in different markets?
Experienced traders agree that the prevailing sentiment in a particular market, coming directly from investors, are far from always based on objective or average data. Since a single trader can follow those automated Forex trading strategies that suit them specifically, another trader has the right to choose completely opposite trading methods and algorithms. Hence, it shows that there is still no single foundation that sets the tone for all market trends.
In order for you to imagine the big picture more clearly, we will give the following example. Specialists in the technical analysis field and day traders rely on market sentiment because technical indicators are affected by market sentiment correspondingly. This means that the forecasts for profit due to short-term price changes and, in fact, the profit itself is largely dependent on dynamically changing market sentiment. In addition, there is such a trading strategy in Forex, when the investor may trade in the direction totally opposite to the market sentiment.
As we can see from this example, different sentiment of market participants form diametrically opposite trading trends, and it is not possible to predict for sure how a particular trader will organize his automated trading in Forex, because this already refers to the sphere of personal psychology of a person, and not only to objective economic realities. The mechanisms of earning money from different investors can be very diverse, therefore, depending on market sentiment, the following types are distinguished:
- trading on the upward price trend (bullish market sentiment);
- trading on a price decline trend (bearish market sentiment);
- trading on overvalued or undervalued assets.
If we talk about the sentiment of market participants in a general sense, then during a period when the stock market is controlled by bulls, the value of securities, including stocks, investment shares and bonds, increases. The opposite is the process of falling prices for stock assets when the bears rule the market. It is believed that market sentiment is inextricably linked with the concept of a fundamental, base price, which, in turn, is already an indicator of the efficiency and reliability of a particular business.
Another interesting trading strategy is making a profit from the sale of shares, the value of which was initially either overvalued or undervalued. As a rule, in order for transactions in securities to be truly profitable, investors of this kind prefer to build on indicators of market sentiment. Of course, it will also be useful for currency traders in Forex to learn about such methods of measuring and predicting market sentiment, in connection with which we turn to the concept of market indicators.
How to measure market sentiment?
To find and select the optimal moment when transactions would bring the maximum profit to the trader, most experienced investors resort to using special indicators of market sentiment. Beginners who are just planning to start developing and testing automated Forex trading strategies should also know what indicators are implied here. Among them, there are four main types, and these indicators influence market sentiment. Let’s take a closer look at them:
- fear index (or Roman numerals VIX);
- moving averages;
- bullish index (expressed as a percentage).
How to correctly interpret market sentiment in terms of the “high-low” parameter? This index allows you to compare assets that have reached an absolute price maximum in 52 weeks with those assets that have fallen in price to a minimum over the same period. Threshold indicators within this index are the numbers 30 and 70, that is, the marks of the minimum and maximum prices. At the lowest reading of 30 points, bearish sentiment prevails in the market, and at the highest, bullish.
Any Forex trader will need to know about the so-called fear index. This index is most relevant to the value of options, but basic knowledge of the VIX index will be useful even when testing automated Forex trading strategies. If this index rises, it signals the need for asset insurance. Accordingly, the fear index itself speaks of the volatility, instability of the market, its increasing volatility, therefore, in this situation, a trader needs to take urgent measures to protect capital or any other assets from risks.
Moving averages are another index for determining market sentiment. This indicator is obtained over a fairly long period of time, and its identification takes from 50 to 200 days. Thus, a sample of 50 and 200 days is used, where the short-term moving average crosses the long-term one, forming “the golden cross”. If at the same time the trading momentum tends to shift upward, then this indicates bullish market sentiment. The reverse trend forms “the death cross” and is an indicator of bearish sentiment.
Finally, the last in our list of market sentiment indices is the Bullish Percent Index, measured purely as a percentage. This index refers primarily to stocks and calculates their number on the basis of figure and dot charts. Neutral markets are considered to contain no more than 50% bullish, while so-called “bullish” markets with a BPI of 80% and above signal the result of over-buying of stocks. The BPI-based market sentiment forecast is interpreted as negative if the index is 20%, which means, assets are already oversold.
Market sentiment in the context of Forex trading
Having a basic knowledge of what market sentiment is and how to measure it using various indicators, a trader is already helping himself by having useful information about the internal structure of the market. It would be natural to assume that this information should be useful to a novice trader when looking for the best Forex trading strategy and when setting up a robot assistant to the required parameters of automated trading. Understanding the economic structure of the market allows you to timely anticipate risky transaction scenarios.
Of course, it is difficult to absolutely accurately identify market sentiment in order to reduce risks to zero, but this measure serves as a good analytical tool for reducing or preventing unprofitable transactions, that is, with a competent assessment of the current market situation, even a novice trader will be able to benefit from emerging trends and trade profitably in Forex. What factors should you always take into account to improve the effectiveness of your automated trading strategy?
First of all, summing up our review, we recall that it is necessary to take into account the micro- and macroeconomic environment, which has a colossal impact on market sentiment. Any crucial social and political events, as well as unforeseen incidents, entail a series of changes in the price range for assets. The ability to correctly read the market sentiment indices and not to lose sight of the psychological component of trading will allow a trader to improve his skills in conducting transactions in Forex.
In order to take advantage of the newly acquired knowledge about market sentiment without any significant harm to your deposit, a reasonable measure for a novice trader would be to pre-test automated Forex trading strategies using a bot – an expert advisor, in which you can set adequate exit values from a trade in advance and make a profit. In this scenario, the trading process will be much safer for the trader, and the study of market sentiment will become an interesting analytical experience, which will certainly come in handy when making large transactions that can bring tangible profits.
