How Can You Trade Relative Strength Index?

Relative Strength Index

A well-liked instrument for day trading and intraday trading is the Relative Strength Index (RSI). You’re in the right place if you’re still learning how to utilise it. This article will emphasise the unique features of this indicator, including what it does. How it calculated, and the purposes for which traders employ it.

What Exactly is Relative Strength Index?

An asset’s or market’s recent price movement measured using the Relative Strength Index (RSI). A technical analysis technique, to assess if an asset or market overbought or oversold. The momentum oscillator known as the RSI oscillates between 0 and 100.

Pay attention to the “mid-line” at 50; traders frequently use this as a cut-off. Traders will view the trend as bullish if the RSI is reading over 50. Typically, traders will view the momentum as bearish if the RSI is below 50. The premise that the pair potentially overbought if the RSI rises above 70 has taken a step further by traders. As an alternative, traders frequently believe that if the RSI is below 30, the pair is not only bearish but also perhaps oversold.

How to Calculate Relative Strength Index?

Calculating the Relative Strength Index (RSI) involves:

J. Welles Wilder, an engineer, mathematician, and trader, created the RSI. When trading stocks and commodities at the time, Wilder ran into a common issue with the timing of trade entry and exit points. In order to address this difficulty and enable traders to properly time long and short entry/exit opportunities, Wilder created a formula.

RSI assigns a grade to the price movement that has occurred between candles over the past ‘X’ periods (where ‘X’ is the input that the trader utilized, which is typically 14 with RSI). To display the “strength” of the market, the RSI measures price fluctuations in relation to earlier price moves.

How Relative Strength Index Works?

When the RSI is over 70 and below 30, said to overbought, and vice versa. If necessary, these conventional levels can also changed to better suit the security. For instance, you could wish to raise this level to 80 if a security is consistently approaching the overbought level of 70.

It should noted that the RSI may spend a lot of time in overbought or oversold conditions during powerful moves.

In addition, the RSI frequently creates chart patterns like double tops and bottoms and trend lines that might not seen on the underlying price chart. Observe the RSI for signs of support or resistance as well.

The RSI typically stays in the 40 to 90 range during an uptrend or bull market, with the 40-50 region serving as support. The RSI typically oscillates between 10 and 60 during a decline or bear market, with the 50–60 area functioning as resistance. These ranges will change based on the RSI parameters and the strength of the underlying trend for the securities or market.

This divergence can indicate a price reversal if the underlying prices hit a new high or low that isn’t supported by the RSI.

A top swing failure has happened if the RSI makes a lower high followed by a downside move below a prior low. A bottom swing failure has happened if the RSI makes a higher low and then follows with an upward movement above a prior high.

Forex Trading Strategy Using RSI

We’ll now change gears and talk about some RSI-based strategy development options. Using the fundamental RSI principles, we will set entry and exit points on the chart based on the signals mentioned above.

Trade Entry RSI

You need to observe a signal from the RSI indicator in order to do an RSI trade. This could be a pattern of RSI divergence or an overbought or oversold RSI.

When the price action on the RSI indicator crosses the appropriate threshold, you would buy or sell the currency pair if you were entering on an overbought or oversold indication.

After the price action closes two or three consecutive candles in the direction of your intended trade, you would place a trade in the direction of the RSI if you were trading a divergence using the RSI indicator.

Stop Loss RSI

The RSI indicator, when employed as a solo instrument, can generate a lot of erroneous or premature indications, as we previously indicated. It is vital to apply a stop loss to guard against losses on our trade, even when combining it with further confirming research.

Beyond a recent swing top or bottom that was formed at the time of the reversal you are trading is the best spot for your stop loss order.

Take Profit on RSI

The fundamental RSI rule indicates that you should hold your trade until the RSI indicator gives you an opposite signal. In addition to being a bullish or bearish RSI divergence, this could also be an overbought or oversold signal. But in practice, it makes sense to use a trailing stop loss or other price action-based rules to take partial or complete profits earlier.

Let’s examine how a straightforward RSI trading technique utilising the guidelines we previously outlined might function.


You are viewing the USD/JPY forex chart for the day. You can see in the image how a trade was entered and exited using only the signals provided by the Relative Strength Index indicator.

The RSI line’s negative trend and the chart’s initial price decline both confirm this. The RSI line abruptly moves into the 30-0 region, generating an oversold signal. Soon after, the price action resumes its downward trend as the RSI line begins to rise. The price movement and the Relative Strength Index now show a positive divergence.

When the RSI line breaks the upward oversold zone, your initial thought might be to open a long position. However, at this point you see the bullish divergence, indicating that the actual entry signal may be better served by waiting for two or three consecutively bullish candles. When this occurs, the chart generates a long signal, allowing you to buy the USD/JPY currency pair under the presumption that the market movement is currently reversing.

A stop loss order should be placed exactly below the bottom that the reversal caused.

After that, the price activity picks up and moves into a bullish trend. Also rising is the RSI line. At least until the RSI indicator crosses the 50 level, the trade could be kept. At that point, you could close out a portion of your position.

Alternately, you may choose to employ some additional price action indicators that offer adequate support for closing the transaction. But in the absence of it, it would be prudent to completely close off the trade when the RSI crosses the 70 overbought level. The close signal is generated when the RSI indicator enters the overbought region, as indicated by the red circle on the chart.
