通达信上升通道主图及选股指标（趋势型）指标公式

买卖信号

1. **买入信号**：当XG条件满足时，在最低价位置显示买入图标（drawicon） - XG条件包含： - 收盘价突破G1（前波段高点）或突破SG（长期趋势线） - D1>D2（近期低点高于前期低点，上升趋势确认） - G1>G2（近期高点高于前期高点，上升趋势确认） - REF(C,T7)/REF(C,T4+1)<1.4（近期涨幅小于40%，防止追高） - BARSCOUNT(C)>200（上市超过200天）

用法

1. **适用场景**：用于选择处于上升趋势中、股价刚刚突破前期高点的股票 2. **注意事项**： - 该指标结合了趋势确认和突破买入两种逻辑 - 要求低点和高点逐步抬高（趋势向上） - 限制涨幅不超过40%，避免追高被套 - 过滤了上市不足200天的新股 - 属于选股指标，适合用于筛选符合条件的股票后再进行人工分析确认 - 图标信号出现在最低价位置，表示参考买入价位
