How to Use RSI in Forex
The Relative Strength Index (RSI) was developed by Wells Wilder and first introduced in his 1978 book New Concepts in Technical Trading Systems. The Relative Strength Index is an oscillator type indicator that moves up and down on the Relative Strength Index in response to a change in market rates.
Widely hailed as one of the most accurate indicators for evaluating current market trend strength, the Relative Strength Index defines two thresholds:
A reading of 30 or under is considered "oversold" and identifies a potential rate increase.
A reading of 70 or higher is considered "overbought" and identifies a potential rate decrease.
