『短线低买高卖』精准把握买卖点！轻松抓黑马稳获利
公式介绍
「短线低买高卖」是一款综合型通达信短线交易公式，融合均线、RSI、MACD、KDJ、量能等多维度指标，兼具趋势判断与买卖信号提示功能。公式核心通过6条不同周期均线（5/10/20/60/120/250日均线）判断股价趋势，结合RSI超买超卖、量能异动、MACD金叉死叉、KDJ低位金叉等信号，精准标注低吸、买入、追涨、卖出及黑马启动信号，同时提示变盘窗口、底背离等关键节点，辅助短线交易者把握波段机会。
使用方法
1. **买入信号**：当K线附近出现红色「吸」「买」、粉色「进」、黄色「追」「底背离」「定乾坤」或白色/紫色「黑马」提示时，结合5日均线向上（红色）的趋势，为低买时机；RSI跌破11后金叉、KDJ低位金叉叠加量能放大时，买入信号更可靠。
2. **卖出信号**：出现绿色「★S」、蓝色「★」、绿色「◆」提示，或RSI超买（JH9跌破84）时，结合5日均线向下（绿色），为高卖节点。
3. **辅助参考**：黄色柱线代表量能异动，「窗,变盘」提示需关注股价方向选择，保护价可作为止损参考。
总结
1. 公式通过多指标共振给出买卖信号，核心看均线趋势+专属文字/图标提示；
2. 买入优先选「吸」「定乾坤」「黑马」等叠加量能放大的信号，卖出关注超买类提示；
3. 需结合大盘环境使用，信号仅作参考，建议搭配止损策略。
