CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

This is a collection of TradingView Pine Script (v5/v6) indicators and strategies for technical analysis. All scripts are standalone .pine files with no build system, package manager, or dependencies — they are pasted directly into the TradingView Pine Editor.

Working with Pine Script

There is no local build, lint, or test toolchain. Pine Script can only be validated by pasting into the TradingView web editor.
All files use //@version=6 (or occasionally v5). Pine Script v6 is the current target.
indicator() declares an indicator (overlay on chart), strategy() declares a backtestable strategy with order execution.
Common overlay settings: overlay=true, max_lines_count=500, max_labels_count=500, max_boxes_count=500, max_bars_back=5000.

File Organization by Category

缠论 (Chan Theory): chan_theory*.pine — Classic Chinese technical theory implementing 分型 (fractals), 笔 (strokes), 线段 (segments), 中枢 (pivot zones). The chan_theory_complete.pine is the most comprehensive version (~62KB), combining both Chan Theory and trend identification. Earlier files are iterative improvements.
EMA Strategies: ema_strategy_4lines.pine, ema_macd_trend_indicator.pine, ema_macd_trend_strategy.pine, ema26_ema52.pine, ema26_ema52_diff.pine — EMA cross/alignment-based trading strategies with MACD confirmation.
Multi-Timeframe EMA52: 多周期EMA52_Pro.pine, 多周期MA52.pine — Draws EMA/MA lines from higher/lower timeframes onto the current chart. _Pro is the latest and most feature-rich.
支撑压力位 (Support/Resistance): 支撑压力位*.pine — Various support/resistance detection indicators (DeepSeek, QwenMax, optimized versions).
趋势判断 (Trend Detection): 趋势行情判断*.pine — Trend condition assessment with optimized/super-optimized variants.
背驰/背离 (Divergence): macd_divergence.pine, high_macd_divergence.pine, kdt_divergence.pine, last_divergence_simple.pine — MACD and K-line momentum theory divergence detection.
Bollinger Bands: bollinger_atr_strategy.pine, bollinger_band_strategy_new.pine.
Other: 裸K趋势反转识别.pine (naked candlestick pattern reversal), close_fft_spectrum.pine (FFT spectrum analysis), 三重滤网均线交易策略.pine (triple-screen MA strategy), 自定义MACD柱子面积.pine (custom MACD histogram area).

Code Patterns

All user-configurable parameters use input.*() grouped with the group= parameter (e.g., group="显示设置").
Display toggles follow the pattern: showX = input.bool(true, "显示X", group="显示设置") with conditional plotting via plot(showX ? value : na, ...).
Color configuration uses input.color() for user-customizable colors.
Chinese is used for parameter labels, tooltips, and comments. Variable names are a mix of English and pinyin (e.g., show_fenxing, color_bi_up).
var prefix is used for persistent state variables (e.g., var bool cycle_in_progress = false).
Many scripts are iterative refinements — when making changes, prefer editing the latest/most complete version (look for _Pro, _complete, _超级优化版, _优化版 suffixes).

Multi-File Relationship

Files in the same category are typically evolutionary versions (simple → optimized → super-optimized → complete). When asked to fix or improve an indicator, identify the latest version first. The README.md and various *.md files contain usage instructions and comparison guides for different versions.
