Engulfing Pattern[SpeculationLab]

14 ago

Overview

This script detects two types of engulfing / outer bar patterns and marks them directly on the chart:
Body Engulfing – The current candle’s body range (open–close) completely covers the entire range (high–low) of the previous candle.
Range Engulfing – The current candle’s full range (high–low, including wicks) completely covers the entire range (high–low) of the previous candle.
Direction logic:
Bull – The previous candle is bearish and the selected engulfing rule is met.
Bear – The previous candle is bullish and the selected engulfing rule is met.
Optional: Require the current candle to have the opposite color of the previous one.
This is an open-source pattern recognition tool for learning, backtesting, and chart review. It is not financial advice.

Key Features
Two detection modes:
body – Body engulfs previous entire range
range – Wicks engulf previous entire range
Direction detection based on the previous candle’s color, with optional opposite-color confirmation
Chart markers: “BULL” /“BEAR” above bars
Alert-ready: built-in conditions for bullish and bearish engulfing patterns

Parameters
Engulfing Type: body / range
body: Current body must fully cover the previous candle’s high–low range
range: Current full range (high–low) must fully cover the previous candle’s high–low range
Require Opposite Previous Candle (default: off):
When enabled, the engulfing pattern must also have the opposite color from the previous candle to trigger

Usage Tips
Engulfing patterns are price action structures; combine with trend, key levels, and volume for context
Signals confirm on bar close (barstate.isconfirmed) to reduce repainting
Can be used with personal risk management rules (stop-loss, take-profit, filters)

Past performance of patterns does not guarantee future results
Trading involves risk; always manage it responsibly

脚本简介
本脚本用于识别两类包裹/外包形态，并在图表上以标记提示：
Body（实体包裹）：当前K线的实体区间（开—收）完全覆盖上一根K线的整个区间（上一根的高—低）。
Range（影线外包）：当前K线的影线区间（高—低）完全覆盖上一根K线的整个区间（上一根的高—低）。

方向判定：
Bull（多）：上一根为阴线且满足所选包裹规则；
Bear（空）：上一根为阳线且满足所选包裹规则；
可选项：要求“当前K线颜色与上一根相反”后再确认（见参数）。
本脚本为开源形态识别工具，适合技术分析学习、回测与复盘，不构成任何投资建议。

主要功能
两种识别模式：body（实体包裹上一根整段） / range（影线包裹上一根整段）。
方向识别：按上一根K线颜色判断多空；可选“当前颜色与上一根相反”的二次确认。
图表提示：plotshape 在K线上方标注 “BULL / BEAR”。
提醒支持：内置 Bullish Engulf / Bearish Engulf 提醒条件。

参数说明
Engulfing Type：body / range
body：当前实体须完全覆盖上一根的高—低整段；
range：当前高—低须完全覆盖上一根的高—低整段。
Require Opposite Previous Candle（默认关闭）：
开启后，除满足包裹规则外，还需当前K线颜色与上一根相反才触发标记。

使用建议
包裹/外包是价格行为结构，建议结合趋势、关键价位、成交量等因素综合判断。
信号在收盘时确认（barstate.isconfirmed），以减少重绘干扰。
可与个人风格的风险控制规则（止损、止盈、过滤条件）配合使用。
