通达信三平底指标（其他）指标公式

买卖信号

- **买入信号**：VAR19（绿转红）- 前一天收绿K（下跌形态），当天收红K（上涨形态），表示下跌趋势可能结束，上涨开始 - **卖出信号**：VAR1A（红转绿）- 前一天收红K（上涨形态），当天收绿K（下跌形态），表示上涨趋势可能结束，下跌开始 - **辅助信号**：三平底、强平底用于识别底部形态

用法

1. **适用场景**：该指标主要用于识别K线形态的转换，特别是下跌转上涨的拐点（买入机会）和上涨转下跌的拐点（卖出风险） 2. **使用方法**： - 当出现绿转红（VAR19）时，可考虑买入 - 当出现红转绿（VAR1A）时，可考虑卖出或减仓 - 三平底、强平底信号出现时，表示可能形成底部形态 3. **注意事项**： - 该指标基于K线形态判断，属于短期交易指标 - 红K表示收盘价高于前一日收盘价（上涨），绿K表示收盘价低于前一日收盘价（下跌） - 建议结合其他技术指标或均线（如MA13）进行综合判断 - STICKLINE函数直接绘制K线颜色，红色代表上涨，绿色代表下跌
