What is the Relative Strength Index (RSI)?

The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements to analyze overbought or oversold conditions in a financial instrument. It was developed in the 1970s by technical analyst Welles Wilder and introduced in his 1978 book “New Concepts in Technical Trading Systems“.

The RSI is displayed as an oscillator, which is a line graph that moves between two extremes – 0 and 100. The indicator signals overbought levels above 70 and oversold levels below 30. When the RSI approaches these extremes, it suggests a potential reversal in price direction.

The RSI calculates momentum as the ratio of higher closes to lower closes – also known as relative strength. This ratio is then smoothed using Wilder’s smoothing techniques to create the RSI line. The default settings use a 14-period RSI with 70/30 overbought/oversold levels.

Why Use RSI for Day Trading?

The RSI indicator has several benefits that make it a useful tool for day traders across any market:

  • Identifies overbought and oversold conditions early – The RSI can spot extremes long before other indicators giving traders an edge in timing entries and exits.
  • Versatile across markets and timeframes – The RSI works equally well on stocks, forex, cryptocurrencies, commodities, and any timeframe from 1 minute to daily charts.
  • Confirms price action and other indicators – Combining RSI with candlesticks, moving averages, chart patterns etc. improves the accuracy of trading signals.
  • Easy to interpret – The RSI scale from 0 to 100 makes overbought above 70 and oversold below 30 intuitive to understand.
  • Customizable settings – The period and overbought/oversold levels can be adjusted to suit different trading styles and securities.

Overall, the RSI’s ability to gauge market momentum and identify turning points makes it a valuable indicator for day traders looking to capitalize on short-term price movements.

How Does the RSI Indicator Work?

The RSI calculation uses the ratio of average upward price changes to average downward price changes over a set period – typically 14 days. There are four key steps:

  1. Calculate price changes: Subtract the previous period’s close from the current close. Up moves have positive values, down moves have negative values.
  2. Average gain: Take the sum of all positive gains over 14 periods and divide by 14.
  3. Average loss: Take the sum of all negative losses over 14 periods and divide by 14.
  4. Calculate RSI: 100 – (100 / (1 + (Average Gain / Average Loss))).

This final value gives the smoothed RSI line that moves between 0 and 100. Most charting platforms do the calculation automatically using these steps.

As new closing prices are added each period, the averages update and the RSI line moves up or down accordingly. When price gains outweigh losses, RSI rises. When losses outweigh gains, RSI falls.

RSI Indicator Settings

The default RSI settings are a 14-period RSI with overbought above 70 and oversold below 30. However, traders can customize the indicator based on their trading style and timeframe:

RSI Period

Overbought/Oversold Levels

  • Raise overbought level up to 80 for strong uptrends
  • Lower oversold level to 20 for strong downtrends

Moving Average Smoothing

  • Wilder’s smoothing (default) is responsive to recent changes
  • Simple moving average is more sensitive to older data

Adjusting the RSI settings to suit the market conditions can improve signal accuracy. However, the standard 14 period RSI often provides a reliable balance.

Using RSI for Overbought and Oversold Levels

One of the most common RSI trading strategies is looking for bounces off overbought or oversold levels.

When the RSI hits above 70, it suggests the security is overbought and may reverse lower. Traders can look to enter short positions on any bearish price confirmation.

Conversely, when the RSI falls below 30, it signals an oversold condition and potential upside bounce. Traders can look to buy on bullish confirmation.

However, overbought/oversold signals should always be combined with other analysis:

Using RSI with other indicators improves timing and avoids acting prematurely on false overbought/oversold readings.

RSI Divergence Trading Strategy

Divergence occurs when the RSI forms highs and lows that don’t match the price action. This signals a disconnect between momentum and price that often foreshadows a trend reversal.

Regular Bullish Divergence

  • Price makes lower low
  • RSI makes higher low = bullish divergence

Regular Bearish Divergence

  • Price makes higher high
  • RSI makes lower high = bearish divergence

Hidden Bullish Divergence

  • Price makes lower low
  • RSI makes higher low = bullish divergence

Hidden Bearish Divergence

  • Price makes higher high
  • RSI makes lower high = bearish divergence

When combined with classic chart patterns or other indicators, RSI divergence can accurately time market turning points weeks in advance. However, false divergences can occur, so wait for confirmation before trading a divergence signal.

RSI Trendline Breakout Strategy

Drawing trendlines on the RSI chart itself can generate trading signals when the lines are broken. This works similar to trendline breaks on the price chart.

To use RSI trendlines:

  1. Connect at least 2 reaction highs or lows on the RSI with a trendline. The more touch points the better.
  2. Trade in the direction of the breakout.
  3. Bullish RSI breakouts signal upside momentum, while bearish breaks indicate downside acceleration.
  4. The key is identifying valid trendlines that accurately fit the RSI’s swings.
  5. Look for breakouts on expanding volume for confirmation.

RSI trendline breaks often foreshadow big moves and allow traders to enter new trends early. However, use other indicators like price action for confirmation before trading the breakout.

Trading RSI Chart Patterns

The RSI indicator can also be used to trade classic chart patterns like double tops, head and shoulders, triangles, flags, and more. The key steps are:

  1. Identify chart patterns forming on the price chart. Look for clear, well-defined patterns.
  2. Look for RSI confirmation. The RSI should reflect the pattern – e.g. lower highs on a head & shoulders top.
  3. Enter trades in the direction of the anticipated breakout. Place stops beyond pattern support/resistance.
  4. Manage the trade according to the price target from the pattern.

When RSI and price patterns align, it creates high probability setups. However, false patterns are common, so wait for confirmation before acting.

Using RSI for Day Trading Confirmation

The RSI indicator can act as a confirmation tool for many day trading strategies across forex, stocks, cryptocurrency, and more. Ways traders use RSI for confirmation:

  • With breakouts – Ensure RSI is aligned with the breakout direction
  • With candlesticks – Combine RSI with reversals like engulfing bars
  • With moving averages – RSI above 50 aligns with bullish crosses
  • With support/resistance – Look for RSI to confirm levels holding
  • With other indicators – Use RSI with MACD, Stochastics, Bollinger Bands etc.

Checking multiple indicators improves timing and avoids acting prematurely on false signals. RSI works well confirming price action and other indicators.

Optimizing RSI Trading Strategies

When optimizing RSI trading strategies, consider these tips:

  • Adjust RSI periods and levels to match the security and timeframe
  • Combine RSI with complementary indicators like MACD and Bollinger Bands
  • Look for confirmation from price action like candlestick patterns
  • Fine-tune entries and exits to match chart levels and structure
  • Test strategies through backtesting and paper trading

No indicator works perfectly on its own. Fine-tuning RSI and combining it with price action and other indicators can improve performance for specific trading styles and securities.

Common RSI Trading Mistakes to Avoid

Some common mistakes traders make when using RSI include:

  • Acting on overbought/oversold levels without confirmation
  • Trading divergences too early before confirmation
  • Forcing trendlines that don’t fit the RSI swings
  • Not accounting for false breakouts and divergences
  • Failing to optimize settings and combine with other analysis

Avoid these errors by waiting for confirmation, fine-tuning RSI, and combining it with price action and other indicators. Patience and combining signals is key for high probability setups.
