📊 Bollinger Band Strategy v1.0

这份 Bollinger Band 工具脚本用于在图表上可视化布林带结构，并识别市场即将爆发的「低波动压缩区」（squeeze）、上下轨突破时机以及潜在的假突破反转信号。用户在 TradingView 图表中加载该脚本后，可以通过观察橙色小圆圈（表示布林带带宽低于阈值）、绿色/红色三角（价格突破上/下轨）以及紫色/青色叉号（free bar 回归）来辅助判断入场、出场或规避信号，从而提高波段交易的胜率与风控能力。适合结合 RSI、MACD 等动能指标进一步增强信号有效性。

// This Bollinger Band tool script is designed to visualize the Bollinger Band structure on a chart,
// identify potential "low volatility squeeze zones", breakout opportunities, and false breakout reversal signals.
// Once loaded in a TradingView chart, the user can monitor:
// - Orange circles: indicate that the Bollinger Band bandwidth has dropped below the defined threshold (squeeze signal),
// - Green/Red triangles: signal when price breaks above or below the Bollinger Bands,
// - Purple/Cyan crosses: suggest a possible fake breakout where price reverts back inside the band (free bar).
// These visual cues help traders better time entries and exits, avoid traps, and improve overall win rate in swing trading.
// This script is best used in combination with momentum indicators such as RSI and MACD to further increase accuracy.
