Quick Review of RSI Basics
RSI Calculation Formula
RSI = 100 - (100 / (1 + RS)) Where RS = Average Gain / Average Loss (14-day period)
Traditional RSI Interpretation
| RSI Value | Traditional Definition | Notes |
|---|---|---|
| > 70 | Overbought, consider selling | Strong stocks can stay overbought |
| < 30 | Oversold, consider buying | Weak stocks can stay oversold |
| > 80 | Extremely overbought | Only consider taking profit |
| < 20 | Extremely oversold | Potential buying opportunity |
Three Advanced RSI Techniques
Advanced Technique 1: RSI Divergence
This is the most powerful advanced RSI technique.
Bearish Divergence (Sell Signal):
- Price makes a new high, but RSI makes a lower high
- Indicates weakening upward momentum
- Suggests a potential trend reversal
Bullish Divergence (Buy Signal):
- Price makes a new low, but RSI makes a higher low
- Indicates weakening downward momentum
- Suggests a potential bottom formation
For more divergence analysis, see MACD and RSI Combined Use.
Advanced Technique 2: RSI Range Trading
In sideways/range-bound markets:
- RSI oscillates between 30-70
- RSI touches 30 + bounce = buy signal
- RSI touches 70 + pullback = sell signal
Combine with Bollinger Bands: RSI < 30 + price touching lower Bollinger Band = stronger buy signal.
Advanced Technique 3: RSI Momentum Confirmation
- RSI > 50 = upward momentum (go long)
- RSI < 50 = downward momentum (go short or wait)
Use RSI 50 as the momentum dividing line. Only trade in the direction of momentum.
RSI + AI: Intelligent Stock Selection
How Does AI Optimize RSI Application?
Traditional RSI uses fixed parameters (14-day) and fixed thresholds (30/70), but:
- Different stocks have different optimal parameters
- Different market environments have different optimal thresholds
- AI can automatically learn the optimal settings from historical data
Three Ways AI Enhances RSI
Method 1: Automatic Parameter Optimization
AI tests different RSI parameter combinations on historical data:
- RSI periods: 5, 10, 14, 20, 30 days
- Overbought thresholds: 60, 65, 70, 75, 80
- Oversold thresholds: 20, 25, 30, 35, 40
Finding the optimal parameter combination for each stock in different periods.
Method 2: Multi-Indicator Fusion
AI simultaneously analyzes multiple indicators and gives a composite signal:
- RSI (momentum) + MACD (trend) + Volume (confirmation)
- Automatically assigns importance weights based on historical performance
Method 3: Market Environment Recognition
AI automatically identifies the current market environment (bull, bear, range-bound) and switches between different RSI strategies:
- Bull market: RSI > 60 is considered momentum confirmation
- Bear market: RSI < 40 is considered momentum confirmation
- Range-bound market: Use RSI range trading strategy

Practical Stock Selection Process
Step 1: Fundamental Screening
Use the Stock Screener to eliminate financially weak companies, scoring 3000+ stocks in real time.
Step 2: Technical Screening
- RSI in 40-60 range (not overbought/oversold)
- MACD above zero line (uptrend)
- Volume > 1.5x average
Step 3: Pattern Confirmation
- Is there a Cup and Handle or VCP pattern?
- Is there support level confirmation?
Step 4: Risk Control
- Stop-loss setting: 5% below pattern low
- Target setting: calculated using risk-reward ratio
Summary
Core advantages of RSI + AI stock selection:
- Dynamic parameters - no longer using one-size-fits-all 14-day RSI
- Multi-dimensional judgment - technical + fundamental + quantitative factors
- Market adaptation - automatically adjusts strategy based on market conditions
- Data-driven - validate strategy effectiveness through backtesting
The intelligent upgrade of traditional indicators is an important step from subjective trading to systematic trading. See Strategy Center for more systematic trading tools.
