RSI

Measure the speed and magnitude of price movements with the most widely used momentum oscillator, identifying overbought and oversold conditions across any market.

What is RSI?

RSI (Relative Strength Index) is a momentum oscillator that measures the speed and magnitude of recent price changes to evaluate whether an asset is overbought or oversold. It oscillates between 0 and 100, with the default calculation period set to 14. Developed by J. Welles Wilder, RSI remains one of the most fundamental tools in technical analysis.

The calculation compares the average gain of up periods to the average loss of down periods over the lookback window. When gains dominate, RSI rises toward 100; when losses dominate, it falls toward 0. The resulting value gives you a normalized reading of momentum that is comparable across different assets and timeframes.

RSI is displayed as a sub-chart indicator below the main price chart. Beyond its standard overbought/oversold readings, RSI is particularly valued for divergence analysis — when RSI and price disagree, it often foreshadows a reversal. Note that DCT Alpha also offers an RSI Heatmap in the analysis tools section, which displays RSI readings across multiple coins simultaneously for a broader market view.

Key Concepts

• RSI Value (0-100): A normalized momentum reading — higher values indicate stronger recent upward momentum, lower values indicate stronger recent downward momentum
• Overbought (above 70): Price has been rising aggressively and may be due for a pullback or consolidation — but in strong uptrends, RSI can remain overbought for extended periods
• Oversold (below 30): Price has been falling aggressively and selling may be exhausted — but in strong downtrends, RSI can stay oversold for a long time
• 50 Level as Trend Filter: RSI above 50 generally indicates bullish momentum, below 50 indicates bearish momentum — this simple filter can keep you on the right side of the trend
• RSI Divergence: When price makes a new high but RSI makes a lower high (bearish divergence), or price makes a new low but RSI makes a higher low (bullish divergence) — this is one of the most powerful reversal signals in technical analysis

How to Use RSI

1. Open Chart from the sidebar and navigate to the indicator settings
2. Enable the RSI indicator — it will appear as a sub-chart below the main price chart
3. Monitor the 70 and 30 levels for overbought and oversold conditions
4. Use the 50 level as a quick trend filter — above 50 favors longs, below 50 favors shorts
5. Compare RSI peaks and troughs with price action to identify divergences

What to Look For

• Bullish signals: RSI falling into oversold territory (below 30) and then turning back up suggests selling pressure is exhausting. Bullish divergence — where price prints a lower low but RSI prints a higher low — is one of the most reliable reversal signals, indicating that downward momentum is weakening even as price continues to fall. RSI crossing back above 50 after spending time below it confirms a shift to bullish momentum.
• Bearish signals: RSI rising into overbought territory (above 70) and then turning down indicates that buying momentum is fading. Bearish divergence — where price makes a higher high but RSI makes a lower high — warns that the rally is running out of steam. This signal is especially powerful at key resistance levels or after extended moves.
• Key patterns: RSI “failure swings” — where RSI enters overbought/oversold, pulls back, fails to re-enter the extreme zone on the next attempt, then breaks its pullback level — are considered high-reliability reversal patterns. In strong trends, RSI often oscillates between 40 and 80 (uptrend) or 20 and 60 (downtrend), which can help you calibrate expectations.
• Combine with: Stochastic RSI for more sensitive timing within the broader RSI context, MACD for trend direction confirmation, Funding Rate and Open Interest to understand whether the overbought/oversold condition is backed by leveraged positioning

Tips

• RSI divergence is most reliable on higher timeframes (4H, daily) — on 5-minute or 15-minute charts, divergences frequently resolve without producing meaningful reversals
• In strong trends, RSI can remain overbought or oversold for extended periods — do not blindly fade an overbought reading in a strong uptrend, as RSI will simply stay elevated
• The 50 level is underrated as a trend filter — a simple rule of only taking longs when RSI is above 50 and shorts when below 50 can significantly improve trade quality
