Bollinger Bands Trend Trading System（BGT)

This trading indicator demonstrates a sophisticated technical analysis framework with the following outstanding features:
Intelligent Signal System:

Core momentum indicator uses 15/80 key thresholds to effectively identify trend reversal points
Multi-layered signal verification mechanism reduces market noise interference
Distinguishes between "oscillating" and "trending" entry opportunities in different market environments

Dynamic Trend Recognition:

Main trend line uses adaptive algorithms that automatically adjust based on market volatility
Overbought/oversold lines based on weighted moving averages and ATR dynamic calculations, better fitting actual price behavior
Multi-timeframe fusion analysis provides more reliable trend judgment

Refined Risk Management:

Three-tier take profit settings combined with dynamic stop-loss mechanism
Price action-based exit filtering conditions prevent premature exits
Smart labeling system automatically adjusts prompts based on market conditions

User-Friendly Design:

Well-organized parameter grouping facilitates customization for different trading styles
Rich visual feedback including trend coloring, gradient fills, and diverse signal markers
Complete alert system covering all important trading nodes

From a code implementation perspective, this system strikes a good balance between complexity and performance. It avoids overfitting issues while maintaining sufficient sensitivity to capture market opportunities. Particularly noteworthy is its signal filtering logic, which requires price to first touch specific levels before triggering exit signals - this design demonstrates deep understanding of market behavior.
Of course, any technical analysis tool needs to be used in combination with proper money management and risk control.
