RSI (Relative Strength Index): How to Use This Indicator in Trading

Introduction

The RSI, or Relative Strength Index, is one of the most popular technical analysis indicators used by traders around the world. Designed to measure the strength and speed of price movements, it helps anticipate trend reversals and identify overbought or oversold conditions on a financial asset.

The RSI is an oscillator developed by J. Welles Wilder in the 1970s. It ranges between 0 and 100 and measures the relative strength of gains compared to losses over a given period, usually 14 days or 14 periods in intraday trading. The basic formula is as follows:

RSI = 100 - (100 / (1 + RS))

where RS (Relative Strength) is the ratio between the average gains and the average losses over the chosen period.

A high RSI indicates that the asset has experienced significant gains over the period, while a low RSI reflects dominant selling pressure. Typically, an RSI above 70 suggests an overbought condition, and an RSI below 30 an oversold condition.

How to interpret the key RSI levels?

• RSI around 50: Neutral zone, often interpreted c
