将 3 个指向数组的指针传递给函数并修改它们

有 3 个类型的数组double。我通过指针将它们传递给函数，为它们分配新的大小，初始化它们。但是退出函数后，数组本身最终并没有改变。错误在哪里？

double *open = new double[LIST_SIZE];
double *high = new double[LIST_SIZE];
double *low = new double[LIST_SIZE];
double *close = new double[LIST_SIZE];
double *volume = new double[LIST_SIZE];
CompressTo(open, high, low, close, volume, date, count, 5);


void CompressTo(double* open, double* high, double* low, double* close, double* volume, Date* date, int &count, int TF)
{
vector<double> newOpen, newHigh, newLow, newClose, newVolume;
vector<Date> newDate;
//Здесь я добавляю в вектора какие-то значения, размер у всех векторов одинаковый.
count = newOpen.size();

open = new double[count];
high = new double[count];
low = new double[count];
close = new double[count];
volume = new double[count];
date = new Date[count];
copy(newOpen.begin(), newOpen.end(), open);
copy(newHigh.begin(), newHigh.end(), high);
copy(newLow.begin(), newLow.end(), low);
copy(newClose.begin(), newClose.end(), close);
copy(newVolume.begin(), newVolume.end(), volume);
copy(newDate.begin(), newDate.end(), date);
}
