K Value (KDJ) and RSI Difference Exceeds 30, Essentially Indicating Severe Imbalance in Market Bullish and Bearish Momentum, with Indicators Showing Extreme Divergence, Triggering "Mean Reversion," Leading to Market Rebound or Pullback.

1. Understand the Two Indicators First
K Value (KDJ):
Range 0–100, Reflects Short-term Price Position and Momentum
>80: Overbought (Overheated); <20: Oversold (Overly Declined)
RSI (Relative Strength Index):
Range 0–100, Reflects Strength of Bullish and Bearish Forces
>70: Overbought (Excessive Buying); <30: Oversold (Exhausted Selling)
2. Difference > 30: Two Typical Situations
1. Rebound Signal: K Value Very Low, RSI Very High (Difference > 30)
Pattern: K <20 (Oversold), RSI > 50 (Relatively Strong)
Meaning:
K Value: Price Has Severely Oversold, Short-term Bearish Momentum Exhausted
RSI: Medium to Long-term Bullish Force Still Present, Downward Momentum Insufficient
Conclusion: Bears Overly Exhausted, Bulls Ready to Rebound → Rebound
2. Pullback / Correction Signal: K Value Very High, RSI Very Low (Difference > 30)
Pattern: K > 80 (Overbought), RSI < 50 (Relatively Weak)
Meaning:
K Value: Price Has Severely Overbought, Short-term Bullish Momentum Exhausted
RSI: Medium to Long-term Bearish Force Still Present, Upward Momentum Insufficient
Conclusion: Bulls Overextended, Bears Ready to Counterattack → Pullback / Correction
3. Why Does a Difference > 30 Trigger Reversal?
Indicator Divergence (Core)
K Value (Short-term) and RSI (Mid-term) Moving in Opposite Directions, Indicating Trend Momentum Breaks
Market Short-term and Mid-term Directions Conflict, Must Be Repaired Through Price Reversion
Overbought/Oversold Resonance
When Difference > 30, at Least One Indicator Enters Extreme Zone (K<20 or K>80)
Overbought Must Correct, Oversold Must Rebound (Mean Reversion Principle)
Imbalance of Bull and Bear Forces
K High, RSI Low: Short-term Buying Overheated, Mid-term Selling Pressure Heavy → Bulls Unable to Continue Rise
K Low, RSI High: Short-term Selling Exhausted, Mid-term Buying Strong → Bears Unable to Continue Drop
4. Practical Judgment (Quick Memory)
Rebound: K <20, RSI > 50, Difference > 30 → Oversold + Bullish Dominance → Rebound
Pullback: K > 80, RSI <50, Difference > 30 → Overbought + Bearish Dominance → Pullback
5. Precautions
Not 100%: In Strong Trends, Indicators May Become Less Sensitive, and Difference May Continue to Widen
Must Combine with Trend: In Bull Markets Watch for Overbought, in Bear Markets Watch for Oversold
Coordinate with Volume and Price: Breakouts with Increased Volume / Breakdowns of Key Levels Are More Effective
Summary in One Sentence: K and RSI Difference > 30 = Extreme Divergence Between Short-term and Mid-term Momentum → Market Self-corrects → Rebound or Pullback.
Rebound and Pullback Trading Method: Show Overbought/Oversold Shadow Bars on Main and Sub Charts; Wait for Overbought/Oversold Shadow Bars to Complete, then Enter Based on the Color of the K-line (Yellow for Long, Gray-Blue for Short, according to the Sub-chart Time Frame).
Follow the Trend: On Larger Timeframes, Reach the Top of the Sub-chart; On Smaller Timeframes, When Trend Bullish or Bearish Appears, Enter, Strictly Follow Stop Profit and Stop Loss!
Numerical Precautions: K Value in Yellow Line, RSI in Purple Line (Difference of Both Values)
K > RSI, RSI Not Crossing Midline, K Overbought, Price Likely to Fall, Expect a Pullback Level
K < RSI, RSI Crossing Midline, K Oversold, Price Likely to Rise, Expect a Rebound Level
(The Larger the Numerical Difference, the Higher the Accuracy, Suitable for Timeframes Above 5 Minutes)
Yellow Text for Bull/Bear: No Delay Signal, Real-time Orders, Stop Loss Before Highs and Lows (Mainly Using 15-Minute and 1-Hour Charts, Confirm Signals with Sub-chart K-line Coloring)
