自定义类型定义说明（Type Definitions）

该库定义了三个核心类型（type），用于结构化处理双顶双底形态识别逻辑：

This library defines three custom types to structurally manage double top/bottom pattern detection logic:

store

TopBottomState

f_detect_top_bottom() 函数

// 引入库（请将 {version_code} 替换为具体版本号） // Import the library (replace {version_code} with the actual version code) import dachengsuper/doublepattern_dacheng/{version_code} as dp // ====================== 以下为 M 顶和 W 底的检测开始 ==================== // ====================== Start of M Top and W Bottom Detection ==================== // 用一个 store 类型的动态数组 sequence 保存最近的枢轴点（最多 3 个） // A dynamic array of type `store` to store recent pivot points (up to 3 points) var dp.store[] sequence = array.new<dp.store>() // 初始化状态对象，用于跟踪当前和历史的顶部/底部状态 // Initialize a TopBottomState object to track current and historical top/bottom state var dp.TopBottomState state = dp.TopBottomState.new(0, 0, na, na, na, na, na, na, 0, 0, 0.0, 0.0) // 调用检测函数：检测是否形成了 M 顶或 W 底 // Call the detection function to check for M Top or W Bottom patterns [DTC, DBC, res_sequence, res_state] = dp.f_detect_top_bottom(x, sig, green, red, sequence, state) // ====================== M 顶和 W 底的检测结束 ==================== // ====================== End of M Top and W Bottom Detection ====================

// 当 DTC 为 true 时，表示检测到双顶形态
// When DTC is true, it indicates a double top pattern is detected

// 当 DBC 为 true 时，表示检测到双底形态
// When DBC is true, it indicates a double bottom pattern is detected

// 示例：如果需要发送 webhook 信号，请加上 `barstate.isconfirmed` 判断，这样就不会重绘
// Example: To send a webhook signal, use `DTC and barstate.isconfirmed` to avoid repainting
