Trading Online Based On The Relative Strength Index
For investors looking to learn stock market investing, technical analysis often provides an unbiased and objective reading on whether or not to take a position in a particular security. As noted in the balance of the series, some technical analysis is simple while the rest can become complicated, particularly for those who are trying to learn stock market investing techniques. The Relative Strength Index of a security is medium to difficult.
What is the Relative Strength Index (RSI) The RSI is an oscillator that measures a security's "relative strength" against its own price history. This technical indicator allows the investor to determine whether the security is currently overbought or oversold and, in fact, provides a better indication of support and resistance levels than the security's price chart would.
How Relative Strength Works Unlike some of the other oscillators covered in our technical analysis series, the RSI is plotted on a scale of 0 to 100. The key levels to remember are 0 to 30 for oversold, 30 to 70 for in range, and 70 to 100 for overbought. Depending on the investor's strategy, these numbers can have different trading implications.
Figuring out the RSI In terms of mathematics, maintaining an ongoing RSI chart is more involved than some other technical analysis calculations. To figure out a security's RSI, we use this formula: 100 - [100/(1 + A)] where A consists of the average "up" days divided by the average "down" days over a predetermined time frame. For example, if a stock closes up 7 days and down 7 days of the past 14 days, then the RSI would be 50.
Using RSI to Trade Securities The RSI is more useful than just providing buy or sell signals to investors. First, the RSI will show areas of support and resistance more clearly than security prices would. Second, overbought and oversold conditions can help determine whether one should sell, buy or hold an existing or non-existing position. They are not typically used on their own to trigger a buy or sell as they provided bearish (0 - 30) and bearish (70 - 100) signals. Using tools such as the RSI to determine safe or unsafe points of entry and exit is really the whole purpose of technical analysis in the first place.
Trading software can alleviate a lot of the time consuming and draining calculations needs to produce a solid buy or sell signal. Although technical analysis involves many aspects and signals, such software can change an individual investor's experience from overwhelmed to simple... or at least make it simpler. - 23199
