How To Use Relative Strength Index (RSI) Indicator In Forex Trading: Ultimate Guide For New Traders

What’s up Traders, in this article, we’re going to be talking about using Relative Strength Index (RSI) Indicator in Forex Trading. The relative strength index (RSI) is a technical analysis indicator that examines the size of recent price fluctuations to determine if a stock or other asset is overbought or oversold.

The RSI is represented by an oscillator (a line graph that travels between two extremes) with a range of 0 to 100. J. Welles Wilder Jr. created the indicator and published it in his important 1978 book “New Concepts in Technical Trading Systems.“

Values of 70 or higher on the RSI, according to traditional interpretation and usage, signal that an investment is becoming overbought or overvalued, and may be ready for a trend reversal or corrective retreat in price. 

A reading of 30 or less on the RSI suggests that the market is oversold or undervalued.

The relative strength index (RSI), which was created in 1978, is a prominent momentum oscillator. The RSI, which is commonly charted beneath the graph of an asset’s price, offers technical traders with clues concerning bullish and bearish price momentum.

When the RSI is above 70%, an asset is deemed overbought, and when it is below 30%, it is considered oversold.

• What’s the difference between RSI and MACD?

The RSI is calculated using a two-step process that begins with the following formula:

The formula uses the average percentage gain or loss over a look-back period as the average gain or loss. The average loss is given a positive value in the formula. 

Periods with price losses are counted as 0 in average gain calculations, while periods with price increases are counted as 0 in average losses calculations.

The initial RSI value is calculated using 14 periods as typical. Consider the case where the market has closed higher seven times in the last 14 days, with an average gain of 1%. The subsequent seven days all ended with a loss of 0.8 percent on average.

The following enlarged computation for the first half of the RSI might look like this:

The second portion of the RSI formula can be calculated after there are 14 periods of data available. The results are smoothed out in the second step of the process.

Calculation of the RSI

The RSI can be calculated using the calculations above, and the RSI line can then be placed beneath an asset’s price chart.

The RSI rises as the frequency and magnitude of positive closes rises, and falls as the number and size of losses rises. 

In a rapidly trending market, the second half of the formula smooths the outcome, thus the RSI will only be near 100 or 0.

While the company is on an uptrend, the RSI indicator can stay in the overbought region for extended periods of time, as shown in the chart above. 

When the stock is in a decline, the indicator may potentially stay in oversold area for a lengthy time. 

For inexperienced analysts, this can be perplexing, but learning to apply the signal in the context of the current trend helps clear things up.

 

What does the Relative Strength Index (RSI) Indicate?

The stock or asset’s primary trend is a useful tool for ensuring that the indicator’s readings are correctly comprehended. 

For example, well-known market expert Constance Brown, CMT, has propagated the theory that an oversold RSI reading in an uptrend is likely much higher than 30%, and an overbought RSI reading in a downtrend is likely much lower than 70%.

As shown in the chart below, during a downtrend, the RSI will peak near 50 percent rather than 70 percent, which can be utilised by investors to more consistently signal bearish conditions.

When a strong trend is in place, many investors will draw a horizontal trendline between 30% and 70% to help them detect extremes. 

When the price of a stock or asset is in a long-term horizontal channel, changing overbought or oversold levels is usually unnecessary.

Focusing on trade signals and strategies that conform to the trend is a related idea to employing overbought or oversold levels relevant to the trend. 

To put it another way, employing bullish signals when the price is in a bullish trend and bearish signals when the stock is in a bearish trend will assist you avoid the RSI’s many false alarms.

RSI and RSI ranges interpretation

When the RSI exceeds the horizontal 30 reference level, it is considered bullish, and when it falls below the horizontal 70 reference level, it is considered bearish.

To put it another way, RSI values of 70 or higher signal that an investment is becoming overbought or overvalued and is likely to see a trend reversal or corrective price decline. 

A reading of 30 or less on the RSI suggests that the market is oversold or undervalued.

RSI values may fall into a band or range during trends. During an uptrend, the RSI should be over 30 and close to 70 on a regular basis. 

The RSI rarely exceeds 70 during a downtrend, while the indicator typically falls to 30 or lower.

These rules can help you gauge the strength of a trend and identify potential reversals. 

If the RSI cannot reach 70 on several successive price swings during an upswing but then falls below 30, the trend has weakened and may be reverting lower.

In a decline, the converse is true. If a downtrend fails to reach 30 or lower and then rises over 70, it has weakened and may be turning to the upside. 

When using the RSI in this fashion, trend lines and moving averages are useful tools to incorporate.

 

Divergences in the RSI as an example 

When the RSI delivers an oversold reading, followed by a higher low that corresponds to similarly lower lows in the market, this is known as a positive divergence. 

This suggests that bullish momentum is building, and a breach above oversold area could signal the start of a new long position.

When the RSI delivers an overbought reading followed by a lower high that matches the price’s higher highs, this is known as a bearish divergence.

A bullish divergence was found when the RSI created higher lows while the price formed lower lows, as shown in the chart below. 

Although this was a valid indication, divergences are uncommon when a stock is in a long-term trend. 

More potential signs can be identified by using flexible oversold or overbought readings.

RSI Swing Rejections as an example

Another trading strategy looks at how the RSI behaves when it resurfaces from overbought or oversold zone. This signal is known as a bullish “swing rejection,” and it consists of four components:

• The RSI has reached oversold levels.
• The RSI returns to a level above 30%.
• Without crossing back into oversold territory, the RSI begins another dip.
• The RSI then smashes through its previous high.

The RSI indicator was oversold, broke up through 30%, and established the rejection low that triggered the signal when it bounced higher, as shown in the chart below. 

Drawing trend lines on a price chart is quite similar to using the RSI in this way.

The bearish version of the swing rejection signal, like divergences, is a mirror image of the bullish version. There are four aspects to a bearish swing rejection:

• The RSI has reached overbought levels.
• The RSI returns to a level below 70%.
• Without crossing back into overbought territory, the RSI forms another high.
• The RSI then breaks through its previous low.

The bearish swing rejection signal is depicted in the chart below. This signal, like most trading approaches, will be most reliable when it follows the long-term trend. 

During downtrends, bearish signals are less prone to cause false alarms.

About the difference between the RSI and the MACD?

Another trend-following momentum indicator is the moving average convergence divergence (MACD), which depicts the connection between two moving averages of a security’s price. 

By subtracting the 26-period exponential moving average (EMA) from the 12-period EMA, the MACD is calculated. The MACD line is the result of the calculation.

The “signal line,” a nine-day EMA of the MACD, is then plotted on top of the MACD line, which can be used as a trigger for buy and sell signals. 

When the MACD crosses above the signal line, traders can purchase the security, and when the MACD crosses below the signal line, they can sell it, or short it.

The RSI was created to show if an investment is overbought or oversold based on recent price levels. 

The RSI is calculated by averaging price gains and losses over a specified time period. With values ranging from 0 to 100, the default time period is 14 periods.

The MACD evaluates the relationship between two exponential moving averages (EMAs), whereas the RSI monitors price movement in relation to recent highs and lows. 

These two indicators are frequently combined to give analysts a more comprehensive technical view of a market.

Both of these indicators are used to determine an asset’s momentum. However, because they measure various things, they might sometimes yield contradicting results. 

For example, if the RSI remains above 70 for an extended period of time, it indicates that the security is overextended on the purchase side.

At the same time, the MACD may imply that the security’s buying momentum is still increasing. 

By displaying divergence from price, any indicator may indicate an impending trend change (the price continues higher while the indicator turns lower, or vice versa).

 

The RSI’s limitations

The RSI is a price momentum indicator that compares bullish and bearish price momentum and presents the findings in an oscillator that can be placed beneath a price chart. 

Its signals, like those of other technical indicators, are most accurate when they follow the long-term trend.

True reversal signals are uncommon, and distinguishing them from false alarms can be difficult. 

A bullish crossover followed by a sharp decrease in a stock, for example, would be a false positive. 

When there is a bearish crossover, but the stock quickly accelerates upward, this is referred to as a false negative.

When an item has substantial momentum in either direction, the indicator might stay overbought or oversold for a long time since it represents momentum. 

In an oscillating market, where the asset price alternates between bullish and bearish moves, the RSI is most beneficial.

 

What is the Relative Strength Index (RSI) and What does it mean?

Traders use the Relative Strength Index (RSI) to determine the price momentum of a stock or other instrument. 

The RSI’s primary concept is to track how quickly traders are bidding up or down on a security’s price. On a scale of 0 to 100, the RSI plots this outcome.

Stocks with ratings below 30 are considered oversold, while those with readings above 70 are considered overbought. 

Traders will frequently post this RSI chart alongside the security’s price chart so that they can compare the security’s recent momentum to its market price.

 

An RSI Buy Signal is a signal generated by the Relative Strength Index (RSI)

If a security’s RSI value falls below 30, some traders consider it a “buy signal,” implying that the security has been oversold and is due for a rebound. 

However, the signal’s dependability will be influenced by the whole context. If the security is in a major decline, it may continue to trade at an oversold level for a long time. 

Traders in that situation may decide to hold off on buying until they get additional confirmation indications.

 

What’s the difference between RSI and MACD?

Both the RSI and the moving average convergence divergence (MACD) are indicators that aim to assist traders comprehend a security’s recent trading behaviour, but in different ways. 

In essence, the MACD smooths out the security’s recent price movements before comparing that medium-term trend line to another trend line that shows the security’s more recent price changes. 

Traders can then decide whether to buy or sell when the short-term trend line comes above or below the medium-term trend line.

 

Definition of the Stochastic RSI -StochRSI

• How to Calculate the Stochastic RSI (Relative Strength Index)
• What does the RSI Stochastic indicate?
• The Relative Strength Index (RSI) and the Stochastic RSI are two different indicators (RSI)
• Use of the Stochastic RSI has its limits

 

What is the Stochastic RSI (Relative Strength Index)?

The Stochastic RSI (StochRSI) is a technical analysis indicator that goes from 0 to 1 (or 0 to 100 on some charting systems). 

And is calculated by applying the Stochastic oscillator formula to a collection of relative strength index (RSI) values rather than normal price data. 

Traders can determine if the current RSI value is overbought or oversold by using RSI readings in the Stochastic formula.

The StochRSI oscillator was created to combine the strengths of both momentum indicators to create a more sensitive indicator that is more sensitive to a given security’s previous performance rather than a broad examination of price change.

Overbought is defined as a StochRSI value above 0.8, while oversold is defined as a reading below 0.2. 

On a scale of 0 to 100, anything above 80 is overbought, and anything below 20 is oversold.

Overbought doesn’t always imply that the price will fall, and oversold doesn’t always imply that the price will rise. 

Rather, the overbought and oversold levels serve as a reminder to traders that the RSI is approaching the extremes of its recent readings.

A reading of 0 indicates that the RSI has reached its lowest point in 14 periods (or whatever lookback period is chosen). 

The RSI is at its maximum level in the last 14 periods if the reading is 1 (or 100).

Other StochRSI numbers indicate how close the RSI is to a high or low.

 

The Stochastic RSI (StochRSI) formulas are as follows:

 

                           max[RSI]−min[RSI]

StochRSI= ———————————-

                                  RSI−min[RSI]

​

 

Where:

RSI=Current RSI reading

min[RSI]=Lowest RSI reading over the last 14 periods

(or your chosen lookback interval)

max[RSI]=Highest RSI reading over the last 14 periods

(or your chosen lookback interval)

 

Where:

RSI = Current RSI reading;

Lowest RSI = Lowest RSI reading over last 14 periods (or chosen lookback period); and

Highest RSI = Highest RSI reading over last 14 period (or lookback period).

​

How to Calculate the Stochastic RSI (Relative Strength Index)

RSI measurements are used to create the StochRSI. The RSI has an input value, usually 14, that tells the indicator how many data periods it will use in its calculation. The StochRSI formula is then applied to these RSI levels.

*For 14 periods, keep track of your RSI levels.

*Note the current RSI reading, the highest RSI reading, and the lowest RSI value on the 14th period. All of the formula variables for StochRSI can now be filled in.

*Note the current RSI reading, maximum RSI reading, and lowest reading for the 15th period, but only for the previous 14 periods (not the last 15). Calculate the new StochRSI value.

*Calculate the new StochRSI value at the end of each period, using only the last 14 RSI data.

 

What does the RSI Stochastic indicate?

Tushar S. Chande and Stanley Kroll created the StochRSI, which was explained in their book “The New Technical Trader,” which was first published in 1994. 

While there were existing technical indicators to highlight overbought and oversold levels, the two created StochRSI to boost sensitivity and give more alerts than traditional indicators could.

When the StochRSI value falls below 0.20, it is considered oversold, indicating that the RSI value is trading at the lower end of its predefined range and that the underlying security’s short-term direction is approaching a low with a likely rise higher. 

A reading above 0.80, on the other hand, indicates that the RSI is nearing extreme highs and could be utilised to signal a decline in the underlying security.

The StochRSI can be used to identify short-term trends by looking at it in the context of an oscillator with a centerline of 0.50, in addition to indicating overbought/oversold conditions. 

When the StochRSI is over 0.50, the security is considered to be trending higher, and when it is below 0.50, the security is considered to be going lower.

To enhance effectiveness, the StochRSI should be utilised in conjunction with other technical indicators or chart patterns, especially considering the large number of alerts it provides.

Furthermore, non-momentum oscillators such as the accumulation distribution line may be particularly useful because their functioning does not overlap and they provide information from a different perspective.

 

The Relative Strength Index (RSI) and the Stochastic RSI are two different indicators (RSI)

Although they appear to be comparable, the StochRSI uses a different formula than the RSI. 

The RSI is a price derivative. StochRSI, on the other hand, is a derivative of RSI or a second derivative of price. 

One of the most significant variations is the rate at which the indicators change.

While the RSI is a considerably slower moving indicator, the StochRSI goes very quickly from overbought to oversold, or vice versa. 

The one isn’t better than the other; StochRSI simply moves more (and faster) than the RSI.

 

Use of the Stochastic RSI has its limits

One disadvantage of utilising the StochRSI is that it is highly volatile, changing quickly from high to low. 

In this case, smoothing the StochRSI may be beneficial. To lessen volatility and make the indicator more useful, some traders will employ a moving average of the StochRSI.

A 10-day simple moving average of the StochRSI, for example, can give a significantly smoother and more reliable indicator. 

Most charting platforms allow you to apply one type of indicator to another without having to do any own math.

In addition, the StochRSI is the price’s second derivative. In other words, its output is two steps away from the actual price of the item being examined, which means it may be out of sync with the market price of the asset in real time at times.

 

The Best Indicators for RSI

 

• What is the RSI and How does it work?
• The MACD
• Crossovers of Moving Averages
• RSI that has been smoothed
• Long-Term RSI (Relative Strength Index)
• The Crucial Points of Livermore

The relative strength index (RSI) is a momentum indicator that measures recent price gains and losses. 

It is generally used by traders and analysts to indicate potential overbought or oversold market circumstances.

Overbought and oversold assets, on the other hand, do not always turn around quickly. 

That is to say, getting confirmation from another trade signal before acting on RSI is advantageous.

When the RSI suggests that a security is oversold or overbought, the MACD can corroborate that it is time to buy or sell. Moving average crossings can also assist RSI users in determining the best moment to trade.

Smoothed RSI uses the moving average method to the RSI indicator itself, making it less jittery and reducing false positives.

Long-term RSI use RSI over a longer period of time, such as weeks or months, to discover a wider trend and ensure that short-term RSI trades are profitable.

RSI can also be used with Jessie Livermore’s key point technique to help identify uptrends and downtrends.

 

What is the RSI and How does it work?

Values on the RSI scale run from zero to one hundred, with readings above 70 indicating overbought situations and readings below 30 suggesting oversold conditions. 

Because the RSI evaluates the size of recent price changes, it is prone to producing false signals when there are large price changes.

The RSI will generally climb as the price of an asset rises since average gains will outnumber average losses. 

When the price of an asset drops, losses usually outnumber profits, leading the indicator to drop.

 

The MACD

Another widely-used momentum indicator, the moving average convergence divergence, can be utilised in conjunction with the RSI and can help corroborate the validity of RSI indications (MACD). 

The relative positions of a short- and long-term moving average are compared in this indicator, which calculates momentum differently than the RSI.

Traders look for signals of momentum deviating from price in the MACD. 

While the price may continue to rise, with the RSI remaining overbought for some time, the MACD begins to demonstrate divergence by beginning to flip down as the price rises. 

This adds to the evidence that a market is approaching a point where it is overextended and, as a result, is likely to retrace soon.

By design, both the MACD and the RSI are contrarian indicators. They defy conventional wisdom by signalling to purchase when there is a lot of selling and selling when there is a lot of purchasing.

When both indicators point to buying, the investment is more likely to be oversold. When both the RSI and the MACD create sell signals, the security is likely overbought and going lower.

 

Crossovers of Moving Averages

Moving average crossovers can also be used to confirm RSI signals of overbought or oversold market conditions. 

The RSI is frequently used to get an early indication of potential trend changes. As a result, using exponential moving averages (EMAs) that respond faster to recent price changes can be beneficial. 

Moving average crossovers that are relatively short-term, such as the 5 EMA crossing over the 10 EMA, are most suited to complement RSI. 

The RSI’s hint of overbought circumstances and likely trend reversal is confirmed by the 5 EMA moving from above to below the 10 EMA. 

An upside crossing, on the other hand, adds to the evidence that a market is oversold.

 

RSI that has been smoothed

The smoothed RSI indicator can also be obtained by applying the EMA procedure to the RSI itself. 

The smoothed RSI is less jittery than the RSI indicator, resulting in fewer false positives and more clearly defined trends. 

Smoothing RSI with an EMA, on the other hand, slows RSI’s response to true changes because all EMAs add lagged factors.

 

Long-Term RSI (Relative Strength Index)

RSI can be utilised with weeks or even months as inputs instead of days, hours, or minutes, which is how it is most commonly employed by traders. 

Short-term trades can be aligned with long-term trends by employing a longer time range. 

A daily RSI purchase signal is more likely to succeed if the monthly RSI is still reasonably low and increasing. 

Similarly, a monthly RSI that is high and decreasing shows that a daily RSI purchase signal is most likely a false positive. 

Finally, if the monthly RSI is very low and dropping, a daily RSI buy signal could signify the start of a new bull market.

 

The Crucial Points of Livermore

The crucial points system of famed trader Jessie Livermore, which should not be confused with pivot points, can also be used with RSI. 

A lot has been said about critical points. The basic concept is that if a security makes a low and then a deeper low, the first low becomes a critical point. 

If the price of the investment rises above that crucial point, the downtrend is over, then it’s time to buy.

Many traders struggle with Livermore’s approach because they can’t tell whether a decline has progressed far enough for key points to be effective. 

With its simple zero to one hundred range, RSI makes this simple. A buy is more likely to yield profits when the RSI is below 30 and a bullish reversal critical point occurs than when any of these signs occurs alone.

As is well known, Livermore preferred to play the bearish side of the market, thus the technique for selling and shorting can be reversed. 

The initial high becomes a bearish reversal critical point when a security achieves a high followed by a second higher high.

Assume the security’s price goes below that critical level but the RSI remains above 70. 

In that instance, it’s probably time to sell the security, possibly shorting it. 

Furthermore, Livermore’s key points can be combined with smoothed RSI to define uptrends and downtrends more precisely.

 

In Forex Trading, the RSI (Relative Strength Index) is used

 

• Forex and the RSI
• Using the RSI to find Trading setups

 

Forex and the RSI

The relative strength index (RSI) is most typically employed to detect when a market is briefly overbought or oversold. 

The RSI can be used to create an intraday forex trading strategy that takes advantage of indicators that a market is overextended and thus likely to retrace.

The RSI is a frequently used technical indicator and oscillator that signals overbought conditions when the RSI value exceeds 70 and oversold conditions when the RSI value falls below 30. 

The more extreme readings of 80 and 20 are preferred by some traders and experts.

The RSI’s shortcoming is that fast, sharp price fluctuations can cause it to surge up and down repeatedly, making it susceptible to false warnings. 

When compared to other signals, such spikes or dips that suggest a trade confirmation could signal an entrance or exit point.

It is not uncommon for the price to stretch considerably beyond the point at which the RSI first suggests that the market is overbought or oversold. 

As a result, a trading strategy based on the RSI performs best when combined with other technical indicators in order to prevent making a trade too soon.

When trading with the RSI, the popular levels to watch are 70 and 30. Overbought is defined as an RSI of 70 or higher. It is deemed oversold when it falls below 30.

When evaluating a trade, RSI indicators are frequently used as a starting point, and many traders set alerts around 70 and 30. The trader will examine the validity of a trade when the alert is triggered.

The RSI can produce false indications, and it’s not uncommon for the RSI to stay over 70 or below 30 for extended periods of time in volatile markets.

 

Using the RSI to find Trading setups

Here are some guidelines for putting together an intraday forex trading strategy that includes the RSI and at least one other confirming indicator:

*Keep an eye on the RSI to see if the market is overbought or oversold.

*Check for signals of an upcoming retracement using other momentum or trend indicators. 

If the RSI indicates oversold readings, for example, a retracement to the upward is expected but not guaranteed.

If one of these extra conditions is met, it is considered good practise to consider entering a trade hoping to profit on a retracement:

*The MACD (moving average convergence divergence) has exhibited price divergence (for example, if the price has made a new low, but the MACD has not and has turned from a downslope to an upslope).

*The average directional index (ADX) has shifted towards a probable retracement.

If the above criteria are met, consider starting the trade with a stop-loss order just beyond the most recent low or high price, depending on whether the transaction is a buy or sell trade. 

The nearest recognised support/resistance level might be used as the starting profit target.

 

When detecting a Stochastic RSI pattern, How can I construct a profitable strategy?

The Stochastic RSI (StochRSI) is most commonly used to create trade strategies by looking for readings in the overbought and oversold areas. 

The StochRSI ranges from 0 to 1, with values below 0.2 indicating oversold conditions and readings above 0.8 indicating overbought situations. 

Bullish indications are oversold values in a large rally, while bearish signs are overbought readings in a large decline.

The increased volatility of the StochRSI, on the other hand, calls for caution. 

Following overbought or oversold readings, trade entry should be delayed until price movement verifies the trend. 

Overbought readings in a downtrend, for example, should be viewed as a warning of a possible move rather than an entry signal.

To validate the sustained negative trend, the StochRSI must fall below the midline at 0.5. 

In a broader positive trend, the StochRSI must move above 0.5 following oversold readings. 

StochRSI readings that stay in oversold or overbought zone for an extended period of time, on the other hand, may indicate a trend reversal. 

 

Using StochRSI as an example

Assume a security has been in a significant downturn for several weeks, with RSI readings ranging from 18 to 60. 

The current session has a value of 56 on the RSI. Though this would not normally be considered an actionable RSI reading, the StochRSI computation suggests otherwise. 

This session’s StochRSI is (56 – 18) / (60 – 18), or 0.9. In a larger downtrend, such a substantial overbought signal indicates that price is likely to resume its slide following the bullish corrective.

Enter a short position using market or limit orders after the StochRSI falls below 0.5, depending on your preference. The bullish retrace’s maximum high serves as a handy stop-loss.

Because bulls have already attempted and failed to push the price above this level, a move over it could signify the conclusion of the bearish trend.

Because the StochRSI provides so many signals, both positive and bad, it’s best to look for additional indicators to confirm trend continuation. The stochRSI signal is strengthened by consistently high volume and candlestick patterns, such as the falling three ways.
