Many investors use RSI as a tool to identify overbought and oversold securities. A rudimentary trading strategy would signal purchasing Apple shares when the RSI is in oversold territory and short selling Apple shares when the RSI is in overbought territory. One can enhance this strategy with the RSI or use another indicator such as a moving average. The RSI can be used across a range of asset classes, such as currency pairs, indices, commodities and shares.
This is a signal that price may be heading towards a top and a downward reversal is about to happen. What the formula means, is that if the price grows against previous values, so does indicator reading; otherwise, oscillator’s value goes down. The RSI line may reach 0 or 100 only during strong, continuous downward or upward trend, respectively.
It is intended to chart the current and historical strength or weakness of a stock or market based on the closing prices of a recent trading period. The indicator should not be confused with relative strength. For example, if the RSI can’t reach 70 on a number of consecutive price swings during an uptrend, but then drops below 30, the trend has weakened and could be reversing lower.
A bullish divergence occurs when the RSI displays an oversold reading followed by a higher low that appears with lower lows in the price. This may indicate rising bullish momentum, and a break above oversold territory could be used to trigger a new long position. A related concept focuses on trade signals and techniques that conform to the trend. The average gain or loss used in this calculation is the average percentage gain or loss during a look-back period. Periods with price losses are counted as zero in the calculations of average gain. Periods with price increases are counted as zero in the calculations of average loss.
You can adjust the appearance of the RSI to your liking, but make sure to keep price lines between 30 and 70 like above. This setting can be changed later as you become more experienced with how everything works. Relative Strength Index is a popular momentum oscillator developed by J. Welles Wilder Jr. and detailed in his book New Concepts in Technical Trading Systems.
Like a moving average crossover signal, this change in trend can be an entry indicator. So if you used a lower RSI period settings, the more sensitive the indicator will be to recent price movements (and it’s just the opposite for higher RSI period settings). The index is easily calculated once the average gain and loss have been determined over a 14-day period.
Traders should apply the RSI together with other technical indicators for the most accurate trading signals. The RSI is usually based on a 14-day time frame, but this can virtual reality stocks be lowered to increase sensitivity or raised to decrease sensitivity. For example, 10-day RSI is more likely to reach overbought or oversold levels than a 20-day RSI.
To exactly replicate our RSI numbers, a formula will need at least 250 data points. In an uptrend or bull market, the RSI tends to remain in the 40 to 90 range with the zone acting as support. During a downtrend or bear market the RSI tends to stay between the 10 to 60 range with the zone acting as resistance. These ranges will vary depending on the RSI settings and the strength of the security’s or market’s underlying trend. Moving average convergence/divergence is a momentum indicator that shows the relationship between two moving averages of a security’s price.
If underlying prices make a new high or low that isn’t confirmed by the RSI, this divergence can signal a price reversal. If the RSI makes a lower high and then follows with a downside move below a previous low, a Top Swing Failure has occurred. If the RSI makes a higher low and then follows with an upside move above a previous high, a Bottom Swing Failure has occurred. The RSI line crossing below the overbought line or above oversold line is often seen by traders as a signal to buy or sell.
- The shorter the period, the steeper indicator’s chart movements will be.
- Overbought refers to a security that trades at a price level above its true value.
- He started trading stocks around 1972 but wasn’t very successful.
- Please note that Wilder does not use the standard moving average formula and the time period may need adjustment.
Click ‘Overlay indicator’ to add an additional Plot to an existing Area. For example, you may be showing Candlesticks in the first Area. You could then add an additional Plot to overlay a moving average. Use the Up and Down buttons to re-arrange the Plot order within the Area.
The indicator will find local tops or bottoms and will help you determine when it’s a good time to trade a potential reversal. The indicator makes use of the RSI to detect extremities and waits until the RSI reverses. Together, these two conditions indicate rising bullish momentum, and a break above oversold territory could be used to trigger a new long position. We can use it to pick potential tops and bottoms depending on whether the market is overbought or oversold.

By putting more emphasis on price action, the concept of positive and negative reversals challenges our thinking towards momentum oscillators. In trending markets, the RSI setting can be even lower (2-6). In this way, traders can identify the best value areas to enter the market in the direction of the dominant trend. For instance, in an uptrend, traders will look to enter buy trades after a pullback that will be indicated by an oversold RSI reading. Similarly, in a downtrend, sell trades will be placed after a retracement that will be highlighted by an overbought RSI reading. Moving averages will confirm the trend and also provide possible retracement target levels where RSI overbought and oversold signals can confirm solid trading opportunities.
Dynamic momentum index is technical indicator that determines if a security is overbought or oversold and can be used to generate trading signals. Since the indicator displays momentum, it can stay overbought or oversold for a long time when an asset has significant momentum in either direction. Therefore, the RSI is most useful in an oscillating market where the asset price is alternating between bullish and bearish movements. As with any technical analysis study, the RSI can be used in conjunction with other tools, including the 200-day moving average.
How to use the RSI indicator?
Andrew Cardwell, Brown’s RSI mentor, introduced positive and negative reversals for RSI and, additionally, turned the notion of divergence, literally and figuratively, on its head. The same idea applies to a security that technical indicators such as the relative strength index highlight as oversold. Traders watching for just such an indication might expect a price correction or trend reversal and buy the security. The standard number of periods used to calculate the initial RSI value is 14. For example, imagine the market closed higher seven out of the past 14 days with an average gain of 1%.
In the RSI equation, the Average Gain and Average Loss variables are computed using only the last X periods, where X is the RSI Period specified. Otherwise, in a non-Morris Modified RSI, these averages are cumulative. The RSI was developed by J Welles Wilder Jr as a momentum oscillator to measure the rate of change of price movements over a specific period.
The 50-day and 200-day moving averages are quite often used as support and resistance levels for gold, silver and mining stocks. The RSI Indicator has proven to be quite useful to gold traders and investors. It could potentially help to identify local tops and bottoms. When trading with RSI, traders also watch out for overbought and oversold signals.
In the above chart, Apple shares consolidated around the 200-day moving average in February. There is generally no RSI formula that can be relied on to determine when the rebound will occur. This means that prices could remain below 20 for months before experiencing a rebound.

Determining the Trend using RSI
The main parameter is the period; It defines the number of price values taken into consideration at plotting the main indicator’s line. The shorter the period, the steeper indicator’s chart movements will be. This parameter is set to 14 by default, and this setting is considered optimal in most cases.
However, they measure different factors, so they sometimes give contradictory indications. For example, the RSI may show a reading above 70 for a sustained period of time, indicating a security isoverextendedon the buy side. The primary currency strength indicator trend of the security is important to know to properly understand RSI readings. For example, well-known market technician Constance Brown, CMT, proposed that an oversold reading by the RSI in an uptrend is probably much higher than 30.
Traders who see indications that a security is overbought may expect a price correction or trend reversal. Typically, traders look for higher highs in price coupled with higher highs in RSI. For example, if a stock makes a new high, but RSI fails to make a new high, there is a bearish divergence between price and momentum.
