c - 用 C 语言编写的回测器

我正在编写一个用于回测股价的代码,最初的编码有一些错误,我在 SO 成员的帮助下发现了这些错误。现在代码已进入最后阶段。我在回测中添加了各种功能。该程序执行以下步骤:

  1. 从txt文件中读取值
  2. 将数据存储到数组
  3. 计算二维数组 mag[][] 中的移动平均值(针对一系列值)
  4. 在每笔交易中指出 MA 与价格的交叉(股票市场的基本 MA 交叉规则)。
  5. 列出交易 list 。
  6. 提供所有值(范围)测试的摘要。

一切似乎都运行良好。所有值在主文件中时都会被打印...但是在完成代码后,为了交叉检查,我尝试再次读取程序末尾的数组值..这次它显示了一些垃圾而不是真实值。

下面是代码

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>
#define MAX_FILE_NAME 100
#define MAXCHAR 1000

int count=0,k1=0,k2=0,k=0;
char filename[MAX_FILE_NAME];
char c; // To store a character read from file

// Get file name from user. The file should be
// either in current folder or complete path should be provided
printf("Enter file name or full path: ");
scanf("%s", filename);
printf("Enter the minimum rolling period for calculation : \n");
scanf("%d", &k1);
printf("Enter the maximum rolling period for calculation : \n");
scanf("%d", &k2);
// Open the file

fp = fopen(filename, "r");

// Check if file exists
if (fp == NULL)
{
printf("Could not open file %s", filename);
return 0;
}

// Extract characters from file and store in character c
for (c = getc(fp); c != EOF; c = getc(fp))
if (c == '\n') // Increment count if this character is newline
count = count + 1;
// Close the file
fclose(fp);
//printf("The file %s has %d lines\n", filename, count);
FILE *myFile;
myFile = fopen(filename, "r");
//read file into array
float numberArray[count];

printf("\nTotal Buy Trades for %d is = %d",k,btradesarray[k]);

}

在检查部分,它正在打印在程序运行期间正确打印的同一变量的垃圾。

以下是输出:
