我写标识股市数据模式的程序,我试图找出以下的短期格局:浮在java中比较识别模式
如果低值低于开盘值由至少3,收盘价格在未平仓值的2以内。
我在读从以下格式的CSV文件中的值,但没有头:
Open High Low Close
353.4 359.2 347.7 349
351.4 354.08 349.1 353.1
350.1 354 349.3 350.2
352.4 353.28 348.7 349.8
345.7 352.3 345.7 351.5
的值存储在一个名为closePrice,openPrice,lowPrice浮动的ArrayList。我正在计算 这是我写的代码,用于尝试识别数据中的模式。
for(int i = 0; i < closePrice.size(); i ++)
{
//Difference between opening price and the price low
float priceDrop = Math.abs(openPrice.get(i) - lowPrice.get(i));
//Difference between opening price and close price (regardless of positive or negative)
float closingDiff = Math.abs(openPrice.get(i) - closePrice.get(i));
float dropTolerance = 3.0f;
float closingTolerance = 2.0f;
if((priceDrop > dropTolerance) || (closingDiff < closingTolerance))
{
System.out.println("price drop = " + priceDrop + " closing diff = " + closingDiff);
System.out.println("Hangman pattern" + "\n");
}
}
那么它应该做的是测试如果价格下降超过3个,然后收盘价距离开盘价的2但是当我运行它,它似乎让一切都绕过if语句。我的输出是:
price drop = 5.6999817 closing diff = 4.399994
Hangman pattern
price drop = 2.2999878 closing diff = 1.7000122
Hangman pattern
price drop = 0.8000183 closing diff = 0.1000061
Hangman pattern
是因为我比较花车吗?任何帮助,将不胜感激。
argh这样一个愚蠢的错误!我花了这么长时间才写出这个问题:谢谢 – James
