Welles Wilder, is a momentum oscillator that measures the speed and change of price movements. The RSI oscillates between zero and Traditionally the RSI is considered overbought when above 70 and oversold when below Signals can be generated by looking for divergences and failure swings.
RSI can also be used to identify the general trend. The RSI is a fairly simple formula, but is difficult to explain without pages of examples. Refer to Wilder's book for additional calculation information. The basic formula is:. The MFI is a momentum indicator that measures the flow of money into and out of a security over a specified period of time.
RSI was developed by engineer, mathematician, and trader J. Welles Wilder. Wilder was a stock and commodities trader at the time and he encountered a common problem regarding timing of trade entry and exit points. There are several ways to use the RSI in trading, which will be outlined in the examples below:. The first two images below represent the most basic method of using the RSI by interpreting overbought and oversold junctures whereby potential trade entry points occur.
Divergence is another valuable way to use the RSI indicator. Divergence is a tool used to spot potential reversals by comparing the movement between indicator and market direction. The charts below illustrate positive bullish reversal and negative bearish reversal divergence signals. RSI measures the relative strength of the market, making this oscillator an invaluable tool that can be employed in virtually any market.
The multiple ways of utilising the RSI allows for traders to become flexible within their trading strategy. Every novice technical trader should definitely have the RSI incorporated into their repertoire.

In addition to the overbought and oversold indicators mentioned above, traders who use the Relative Strength Index RSI indicator also look for centerline crossovers. A movement from below the centerline 50 to above indicates a rising trend. This indicates the market trend is increasing in strength, and is seen as a bullish signal until the RSI approaches the 70 line. A movement from above the centerline 50 to below indicates a falling trend. This indicates the market trend is weakening in strength, and is seen as a bearish signal until the RSI approaches the 30 line.
RSI can be used just like the Stochastic indicator. We can use it to pick potential tops and bottoms depending on whether the market is overbought or oversold. On June 7, it was already trading below the 1. However, RSI dropped below 30, signaling that there might be no more sellers left in the market and that the move could be over. RSI is a very popular tool because it can also be used to confirm trend formations. Bullish divergence occurs when price makes a new low but RSI makes a higher low.
Wilder thought that "failure swings" above 50 and below 50 on the RSI are strong indications of market reversals. If it falls below 72, Wilder would consider this a "failure swing" above Finally, Wilder wrote that chart formations and areas of support and resistance could sometimes be more easily seen on the RSI chart as opposed to the price chart. The center line for the relative strength index is 50, which is often seen as both the support and resistance line for the indicator.
If the relative strength index is below 50, it generally means that the stock's losses are greater than the gains. When the relative strength index is above 50, it generally means that the gains are greater than the losses. Cardwell observed when securities change from uptrend to downtrend and vice versa, the RSI will undergo a "range shift.
Next, Cardwell noted that bearish divergence: 1 only occurs in uptrends, and 2 mostly only leads to a brief correction instead of a reversal in trend. Therefore, bearish divergence is a sign confirming an uptrend. Similarly, bullish divergence is a sign confirming a downtrend. Finally, Cardwell discovered the existence of positive and negative reversals in the RSI. Reversals are the opposite of divergence. For example, a positive reversal occurs when an uptrend price correction results in a higher low compared to the last price correction, while RSI results in a lower low compared to the prior correction.
A negative reversal happens when a downtrend rally results in a lower high compared to the last downtrend rally, but RSI makes a higher high compared to the prior rally. In other words, despite stronger momentum as seen by the higher high or lower low in the RSI, price could not make a higher high or lower low.
This is evidence the main trend is about to resume. Cardwell noted that positive reversals only happen in uptrends while negative reversals only occur in downtrends, and therefore their existence confirms the trend. A variation called Cutler's RSI is based on a simple moving average of U and D ,  instead of the exponential average above. Cutler had found that since Wilder used a smoothed moving average to calculate RSI, the value of Wilder's RSI depended upon where in the data file his calculations started.
Cutler termed this Data Length Dependency. Cutler's RSI is not data length dependent, and returns consistent results regardless of the length of, or the starting point within a data file. From Wikipedia, the free encyclopedia.
