What is the RSI Indicator?

The RSI (Relative Strength Index) is a momentum indicator that helps traders measure the speed and change of price movements. It is displayed as a line graph that moves between 0 and 100.

When the RSI value is above 70, the market is considered overbought, which means the price may soon drop. 

When the RSI is below 30, the market is oversold, meaning the price may soon rise.

Traders use RSI to confirm if an asset is trending up or down.

RSI helps traders spot trend reversals before they happen.

How to Set Up Your RSI Indicator Step-by-Step

The Relative Strength Index (RSI) is available on most trading platforms like MetaTrader 4 (MT4), MetaTrader 5 (MT5), TradingView, Binance, and other charting software. 

Below is a step-by-step guide to setting it up.

Step 1: Open Your Trading Platform

• If you’re using MT4/MT5, launch the platform and open a chart.
• If you’re using TradingView, open a chart of your preferred asset.
• If you’re using Binance, go to the Trading section and open the chart.

Step 2: Add the RSI Indicator

For MetaTrader 4 & 5 (MT4/MT5)

• Click on “Insert” in the menu bar.
• Select “Indicators” – “Oscillators” – “Relative Strength Index (RSI)”
• A settings window will appear.

• Click on “Relative Strength Index” to add it to your chart.

For Binance (Web or App)

• Click on “Indicators” at the top.
• Search for RSI and select it.

Step 3: Adjust RSI Settings

After adding the RSI, you’ll see a settings window. You can modify:

Period (Default: 14): This determines how many past candles RSI considers.

Overbought Level (Default: 70): Signals a possible sell.

Oversold Level (Default: 30): Signals a possible buy.

Line Color & Thickness: Customize for better visibility.

For shorter-term trading, some traders use:

RSI 6 for very short timeframes.

RSI 12 or 24 for medium-term trends.

Step 4: Apply RSI to Your Chart

Click OK or Apply, and the RSI will appear below your price chart as a separate indicator.

Step 5: Use RSI for Trading

Common RSI Mistakes and How to Avoid Them

The Relative Strength Index (RSI) is a great tool for spotting overbought and oversold conditions, but many traders make mistakes when using it. 

Below are the most common RSI mistakes and how to avoid them:

1. Relying Only on RSI for Buy/Sell Signals

Many traders think that when RSI is above 70, it’s an automatic sell, and when it’s below 30, it’s an automatic buy. This can lead to losses if the market stays in an overbought or oversold state for a long time.

Solution

Combine RSI with other indicators like Moving Averages, MACD, or trendlines to confirm signals.

Look for RSI divergence instead of just overbought/oversold levels.

2. Ignoring the Trend

Using RSI the same way in both trending and ranging markets.

In strong uptrends, the RSI can stay above 70 for a long time without reversing.

In strong downtrends, the RSI can stay below 30 without bouncing back.

Solution

In an uptrend, RSI near 30 is a better buying opportunity than waiting for it to reach 70 to sell.

In a downtrend, RSI near 70 is a better selling opportunity than expecting it to reverse at 30.

3. Using the Default RSI Setting for Every Market

The default 14-period RSI doesn’t work well in every market condition. It may be too slow or too fast depending on your strategy.

Solution

For short-term trading (scalping/day trading): Use RSI 6 or 9 for quicker signals.

For long-term trading (swing trading): Use RSI 20 or 24 for more stable signals.

4. Misinterpreting RSI Divergence

Assuming that RSI divergence (when RSI moves in the opposite direction of price) always leads to a trend reversal. 

Sometimes, the trend continues despite divergence.

Solution

Use support/resistance levels to confirm divergence signals.

Wait for price action confirmation (e.g., a trendline break or candlestick reversal pattern).

5. Ignoring RSI Failure Swings

Not recognizing when RSI signals a strong breakout.

A failure swing happens when RSI moves into overbought or oversold territory but does not return to normal levels, it indicates a strong trend continuation.

Solution

If RSI breaks above 70 and stays above 50, it confirms a strong uptrend.

If RSI breaks below 30 and stays below 50, it confirms a strong downtrend.

6. Overcomplicating RSI Strategies

Adding too many indicators with RSI, leads to confusion and conflicting signals.

Solution

Keep it simple! Use RSI with one or two other indicators like:

Moving Averages (to confirm trend direction)

MACD (to confirm momentum)

Support/Resistance Levels (to identify strong reversal points)

What is a Good RSI Number to Buy?

A good RSI level for buying depends on market conditions and your trading strategy:

• Traditional Approach: Buy when RSI is below 30 (oversold zone).
• Trend-Following Strategy: In an uptrend, RSI around 40-50 can signal a good buying opportunity.
• Divergence Strategy: Buy when RSI makes a higher low while price makes a lower low (bullish divergence).

Don’t rely only on RSI, combine it with trendlines, moving averages, or support/resistance for better confirmation.

How to Set RSI Indicator Alerts

• Slow RSI (for confirmation): 21-period RSI
