如何在股票数据的收盘价中找到V [英] How to find a V in an array of close price for stock data

问题描述

 如果我要绘制数据数组，我可以看到V何时出现.我希望我的程序使用股票的收盘价来查找何时出现V.怎么办呢?

 If i were to plot the array of data i could see when the V occurs.  I would like my program to find when a V occurs using minute close price of stock.  How can this be done ?

谢谢

推荐答案

您正在寻找局部最小值.您需要做的就是保留最后一个值，并保留有关库存是否最后增加的标志.如果它正在减少(标志为假)，但是新值更高 比您之前的价格要低.如果价格在增加(标志为true)，但新价格较低，则您已达到本地最高价.

You are looking for a local minimum.  All you should need to do is keep the last value, and keep a bool flag of whether the stock was last increasing.  If it was decreasing (flag is false), but the new value is higher than your previous price, you have a minimum.  If it was increasing (flag is true) but the new price is lower, then you have hit a local maximum.
