K 线基础与结构

Lesson Overview

In "Technical Analysis Intro" → "K 线与价格行为", this lesson "K 线基础与结构" builds knowledge you can apply immediately.

K线的实体和影线由OHLC决定，颜色不是定义。高必须不低于开/收，低必须不高于开/收；不满足约束的数据应先隔离，不能直接用于形态判断。 检查OHLC有效性→算实体绝对值→算上影H−max(O,C)→算下影min(O,C)−L→写方向及计量单位。 本课作业：A=(100,108,98,106)，另有B=(100,99,98,101)。计算A实体影线，判断B是否有效。

Core Concepts

These points align with the video walkthrough—take notes as you watch.

• ▸K线的实体和影线由OHLC决定，颜色不是定义。高必须不低于开/收，低必须不高于开/收；不满足约束的数据应先隔离，不能直接用于形态判断。
• ▸检查OHLC有效性→算实体绝对值→算上影H−max(O,C)→算下影min(O,C)−L→写方向及计量单位。
• ▸本课作业：A=(100,108,98,106)，另有B=(100,99,98,101)。计算A实体影线，判断B是否有效。
