带MACD/EMA确认的高低点摆动策略

KaizenTraderB的带MACD/EMA确认的高低点摆动策略。

我设计这个指标是为了配合市场结构突破策略。它标记MACD确认的波动高点和低点。它还显示更高的时间范围快速和慢速EMA，以确定方向偏差。还提供警报，指示下跌趋势中的低谷摆动和上升趋势中的高谷摆动。它在最后一次上下摆动时画一条水平线。

在输入时间段上显示此指示器，并在设置中选择较高的时间段。您还可以更改波动高点和低点以及均线的回溯期。

当我使用它时，我在寻找HTF趋势方向上的摆动高/低突破然后，寻找突破价格水平和流动性区域（wicks、order Block、price拥塞）之间的回调，以进入均线趋势。
