tradingview上面有一个超级趋势策略,截止到今天的获赞数量42483. 一看就是 抢手货色,我也用了很久,我们来看看这个超级趋势策略的表现:
我们可以基本清晰的看到这个超级趋势策略出来的信号相对及时. 但由于指标的滞后性,我把它放到自己的框架里去接收交易信号的时候还是有一些困惑.
1.单从买卖信号来看,回测看的数据目前没有特别明显的赚钱效应. 2.这个超级趋势策略里面有一个信号转折点. 这个转折点我到现在还没搞清楚派啥用场,经常让我在交易信号过滤的时候搞不清楚,干扰了我的正常过滤规则.
之前的的信号过滤规则是如果相同的标的,在相同周期内,连续两个交易信号都是相同方向的,那么最近的相同方向的信号就过滤掉不管它. 现在这个信号转折点一来,我有点懵逼...
下面是supertrend的超级趋势 指标的源代码,大家空了收藏一下,我有时间给它换成python的...
