BOLL + RSI 趋势信号

📘 Strategy Name

BOLL + RSI Dot Cluster Strategy (Unfiltered Base Version)

⸻

🎯 Overview

This strategy combines Bollinger Bands (BOLL) with the Relative Strength Index (RSI) to identify short-term overbought and oversold conditions. By detecting when price breaks out of the BOLL channels and confirming with RSI extremes, the strategy generates buy/sell signals with graded strength, visualized through stacked colored dots on the chart.

⸻

🔍 Core Logic

🟢 Buy Signal Conditions:
• Price closes below the lower Bollinger Band, indicating potential market oversold conditions or capitulation;
• RSI is below the oversold threshold (default: 30), confirming technical oversold status;
• When both conditions are met, a buy signal is generated.

🔴 Sell Signal Conditions:
• Price closes above the upper Bollinger Band, suggesting a sharp short-term rally;
• RSI is above the overbought threshold (default: 70), confirming technical overbought status;
• When both conditions are satisfied, a sell signal is triggered.

📊 Signal Strength Scoring System

Each signal is scored from 1 to 5 based on:

Dimension Logic Score Range
RSI Score Based on how extreme the RSI is (e.g. >90 or <10 scores highest) 1–5
Price Distance Score Based on the percentage deviation of the current price from the Bollinger middle band 1–5

• The final signal strength is the average of both scores (rounded), capped at 5.
• Signals are visualized as 1 to 5 stacked dots (green for buy, red for sell) above or below the candles.

🧭 Use Cases & Suitability
• Designed as a visual manual trading aid;
• Can serve as a signal confirmation module for other strategies;
• Particularly suited for volatile assets such as BTC, ETH, altcoins, and momentum stocks;
• Works well on 1H, 4H, or daily charts;
• Not recommended for blindly shorting during strong uptrends (unless used with stop-loss logic).

⸻

⚠️ Key Characteristics & Limitations
• This is a base version — no trend filters, cooldown mechanisms, or lockouts are applied;
• May generate consecutive opposite signals during strong trends (e.g., repeated sell signals during an uptrend);
• Users are encouraged to customize or enhance this strategy with:
• Trend filters (e.g., EMA, MACD);
• Cooldown intervals;
• Volume or divergence confirmations;
• All signals are probabilistic and do not constitute financial advice.

🔔 Visual Guide
• Green dots stacked below candles represent buy signals;
• Red dots stacked above candles represent sell signals;
• The number of dots = signal strength (1–5);
• Bollinger Bands are plotted in white, the midline in yellow, with a subtle white background channel.
