RSI (Relative Strength Index) Indicator – A Smart Tool for Online Trading on MT5 & Web Trading Platforms

Technical indicators are essential for online trading. The most reliable and widely used momentum indicators are RSI (Relative Strength Index). RSI works irrespective of whether you are trading Forex, Gold, Indices, Stocks, or Commodities through MT5 or any web trading terminal. RSI gives traders the opportunity to gauge market momentum, determine when a market is overbought, and identify when a market is oversold.

What is RSI (Relative Strength Index)?

Relative Strength Index or RSI is a momentum oscillating indicator created by J. Welles Wilder Jr. RSI is a scale of 0 to 100 measuring the speed and magnitude of price changes.

The RSI indicator primarily answers the question if a price of a financial asset is:

  • Overbought (overvalued)
  • Oversold (undervalued)

The most popular setting of RSI is 14 periods which means that the indicator evaluates the last 14 candles or price periods.

How RSI Works

RSI = 100 – 100 / 1+RS

Where:

  • RS = Average Gain ÷ Average Loss
  • RSI can range from 0 - 100

Standard RSI Levels

  1. Above 70 → Market is usually overbought
  2. Below 30 → Market is usually oversold
  3. Around 50 → Momentum is neutral

These levels also help traders determine if a trend is likely to be continued or get reversed.

RSI Function in Trading

The RSI (Relative Strength Index) is an important online trading indicator that does multiple things:

1. Identifying Overbought Markets

RSI reading over 70 is indicative that buyers are most likely to push the price higher too quickly. This means traders should be ready for possible price corrections or bearish reversals and traders should begin to sell short.

2. Identifying Oversold Markets

RSI reading below 30 is indicative of strong selling pressure to which traders respond by anticipating the bullish rebound and traders should begin to buy long.

3. Confirming Trend Strength

RSI confirms strong or weak trends. Here are some clues to trends:

  • RSI above 50 is bullish momentum.
  • RSI below 50 is bearish momentum.

4. Detecting Divergence

Divergence is detected when price movement and RSI move in opposite directions of each other.

Here are some examples of Divergence:

  • When price makes a new high, but RSI fails to make a new high, then you are in a possible bearish reversal.
  • When price makes a new low, but RSI forms a higher low, then you are in a possible bullish reversal.

Detecting Divergence is the most powerful RSI signals that are used by professional traders.
