The Relative Strength Index (RSI) is an extremely popular trading tool that attempts to define overbought and oversold conditions in an underlying market. It was created by J. Welles Wilder and introduced in <\/span>Commodities <\/span><\/i>Magazine in 1978.\u00a0<\/span><\/p>\n RSI is a momentum oscillator that measures the speed and magnitude of recent changes in an underlying security or futures contract. The oscillator varies from 0-100 based on a calculation of average price gains vs. average price losses calculated over 14 periods.<\/span><\/p>\n Here is the actual RSI equation:\u00a0<\/span><\/p>\n While it is important to understand the underlying math to know what you are viewing, RSI is now a standard part of nearly all charting packages, so traders can simply pull it up on an existing chart with a click of a button. They can even alter its metrics\u2014changing the number of previous trading periods to calculate it and setting their own levels for overbought and oversold; though we would not encourage that.\u00a0<\/span><\/p>\n Wilder described five things that the RSI tells traders in his book, \u201cNew Concepts in Technical Trading Systems<\/a>.\u201d\u00a0 They are: Tops and bottoms, chart formations, failure swings, support and resistance, and divergence.\u00a0<\/span><\/p>\n When the RSI oscillator ranges above 70, it indicates overbought conditions, and when it drops below 30, it indicates oversold conditions. Simply put, these levels can indicate a top or a bottom in the market. Short of that, they can also indicate corresponding support and resistance levels in the underlying market or the oscillator.\u00a0<\/span><\/p>\n Below is a daily crude oil chart. Notice how often the market reverses after the RSI hits overbought (green line) or oversold (red line) territory. <\/span><\/p>\n Looking closer at the June 2022 period shows that the RSI formed a well-defined bearish head and shoulders pattern prior to the sharp sell-off.\u00a0<\/span><\/p>\n You can also see from the June 2022 rally that markets can remain overbought for quite some time.\u00a0<\/span><\/p>\n Perhaps the strongest signal the RSI produces is of market reversals when there is a divergence between the indicator<\/a> and the underlying price chart. \u201cDivergence occurs when the RSI is increasing, and the price movement is either flat or decreasing, [or] when the RSI is decreasing, and price movement is either flat or increasing,\u201d Wilder wrote.\u00a0<\/span><\/p>\n If you look closely at the second crude oil chart above, you can see that the RSI turned sharply lower while crude traded relatively flat at the top of the move. This divergence indicated a sharp sell-off was imminent.\u00a0<\/span><\/p>\n It is important to remember that the RSI is simply a measure that\u2014based on research\u2014indicates that a specific market\u2019s momentum could be waning. It is not a panacea but a tool that has proven valuable when used properly. Markets can remain overbought or oversold for some time, so RSI is best used in conjunction with other indicators or strategies to confirm a market outlook.\u00a0<\/span><\/p>\n J.B. Maverick suggests in an Investopedia post that using the RSI in conjunction with the Moving Average Convergence Divergence (MACD)<\/a> indicator can produce strong reversal signals. MACD is a trend-following momentum indicator that shows the relationship between two moving averages. \u201cMACD shows divergence by beginning to turn down as the price continues to advance,\u201d Maverick writes. \u201cThe MACD can confirm that it is time to buy or sell when RSI indicates a security is oversold or overbought.\u201d<\/span><\/p>\n One of the simplest strategies to trade is the moving average crossover. When the shorter-term moving average crosses above the longer-term moving average, it is a sign of upward momentum; when it crosses below the longer-term moving average, it is a sign of downward momentum. While such a strategy can be successful, it rarely works consistently on its own. But when you use other indicators to confirm this signal\u2014such as a bearish cross while RSI is overbought\u2014it can strengthen the signal and form a more consistent strategy.\u00a0<\/span><\/p>\n While some analysts have had some success in manipulating the RSI\u2014using different time periods and defining overbought\/oversold at different levels than the standard 30-70, it is best to stay with the original metrics absent compelling research.\u00a0<\/span><\/p>\n<\/p>\n
