夜雨聆风它不是那种花里胡哨的垃圾指标，它的底层是最小二乘法加权算法，不用你手动画线、不用你调参数、不用你找高低点，全程全自动识别有效趋势通道。
它最大的核心亮点，就是支持九周期全周期共振扫描。
从一分钟、五分钟、十五分钟，一直到小时线、日线、周线、月线，全周期同时运算！大周期帮你定整体趋势方向，小周期帮你抓精准入场点位，多周期通道重合，就是高概率稳定行情。
而且它自带专业级多重过滤，彻底杜绝无效通道、杂波行情。
自带黄金分割过滤、通道宽度过滤、极值高低点过滤，太窄、太宽、不稳定的垃圾通道，它直接帮你过滤掉，只留给你高胜率有效通道。
趋势行情，你可以开启极值模式，通道紧贴高低点，完美跟随趋势走完全程；震荡行情，用等宽通道模式，上轨压力高抛、下轨支撑低吸，买卖位置一目了然。
可视化做得也特别舒服，自动上色、自动填充通道区间、自动画趋势辅助线，整张盘面干净清晰，新手一眼看懂支撑压力，老手直接用来共振抓拐点。
