Forex Trading Charts And The Relative Strength Index

Momentum oscillator charts are useful investing tools that track the velocity of price movement. The Relative Strength Index (RSI), created by Welles Wilder, helps traders identify markets that are either oversold or overbought. When evaluating a currency with the RSI, the recent gains are measured against recent losses. It is then assigned a value from 0 to 100.

Oversold markets are those in which stock prices are considered too low. Overbought markets, by contrast, are those in which stocks have a higher price than their actual value. When RSI scores fall below 30, it tells traders that the market is oversold. At the other end of the spectrum, scores above 70 point to a market that is overbought. While many traders use the 30 and 70 markers as signals to buy and sell, others opt for 20 and 80. This is a stronger indication that a reversal or price correction is imminent.

Being able to recognize trends is important in making successful Forex trades, and the RSI can help with this as well. The center line, 50, indicates a stable market. You may be able to spot an uptrend by looking at the RSI score. If it is above 50, it can mean that currently, average gains outweigh average losses. Evidence of a down trend, on the other hand, can come with RSI scores below the center line.

RSI and other indicators are useful only during established trends. Within any given day, there will be price fluctuations which are normal parts of the market. Trends, however, last up to several months and indicate where the market is overall. Those interested in day trading will not find the RSI helpful in closing trades as it is a medium to long-term investing tool.

How does the RSI calculate momentum? When a trader uses an RSI program, it calculates scores by looking at the averages from past periods. Typically, at least 14 periods are used to ensure a balanced overview of the market. There are two different theories on using an RSI and improving its accuracy. If one increases the number of periods beyond 14, the score is more accurate. However, it will be more difficult to spot an emerging trend early. On the other hand, one may use fewer periods to calculate scores and get in on trends sooner. The downside to this is that it is possible to get a less accurate result, which may affect trading.

Momentum oscillators, the RSI in particular, are extremely useful in helping investors spot trends and time trades. Easy to read and often very accurate, the RSI can help maximize profits and minimize gains. It is not, however, foolproof. Traders have to balance the need to get in on trends early with the having the most accurate information. It can easily happen that a trader jumps on a perceived trend that does not materialize. As part of an overall investment strategy and in conjunction with other indicators and charts, though, the RSI is invaluable.
