交叉点数

Question

所以我试图找出我要去哪里。现在，我只想计算在定义的时间段内价格超过或低于斐波那契线（F0）的次数，但由于某种原因，它没有在斐波那契线附近计算蜡烛。我需要更改什么？

Answer 1

您在crossing中的条件基于F236，而不是F0，这就是为什么不一致的原因。这些条件也不同于使用cross函数（该函数用于测试两个序列之间的杂交）。

附带说明，也可以通过使用以下更简单的形式来计算十字架：

counts = cum(crossing ? 1 : 0)

根据您的情况，请提供：

crossing = (high>=F0 and low<=F0) or (high<=F0 and low>=F0)
theCount = cum(crossing?1:0)

或以下代码，如果您想改为使用cross函数：

crossing = cross(high,F0) or cross(low,F0)
theCount = cum(crossing?1:0)
