自在买卖

通达信自在买卖指标公式-通达信公式｜查看原文 ↗

🔧 核心通用·带A股选股过滤（核心可用 · 把'去ST/选板块/CODELIKE'那行删掉，美港马加都能跑）

周期：短线用途：只管进单(找买点/选股)（纯多·只做多)

📊 把公式 自在买卖 实时算进主散博弈(纯技术函数;选股/筹码特殊函数会标注不支持)　

🧩 这个指标拆开看 = 哪些"积木"组合的

① 定方向（趋势）

均线类 MA/EMA — 一段时间的平均价，铺出趋势中枢、看多空排列

MACD — 快慢均线之差，测趋势动能、金叉死叉

④ 触发（信号扳机）

CROSS 交叉 — 两线金叉/死叉当买卖扳机

搭条件的零件

HHV/LLV/REF 等 — 取区间最高最低、引用前N根——搭条件的零件

图上标注买卖点

画线/标注 — 在图上画柱、标买卖点、上色提示（只是显示，不是判断逻辑）

⚠️ A股专属（港股/美股/马股/加密都没有）

去ST/风险股 — 剔除A股ST风险股

组合思路：用均线/MACD 定方向，再用金叉/突破当买卖扳机。把几件事叠在一起同时成立，才算一个'信号'——叠得越多看着越细，但也越容易过度拟合。 ⚠️ 这条含 A股专属逻辑（涨停板/龙虎榜/代码板块）——只有大陆A股有这制度，港股、美股、马股、加密统统没有，这部分搬不过去。
