There is a text file that contains numbers like:

10962
11433
13226
12232

I need to find the maximum number among these numbers, so I do the following:

//Открываю файл
int file_1 = FileOpen("ch/DOWNLINE.TXT",FILE_TXT|FILE_READ); 

//Читаю все числа в массив
string arr_1[];
FileReadArray(file_1,arr_1,WHOLE_ARRAY);

//Пытаюсь найти максимальное число в массиве
int maximum =  ArrayMaximum(arr_1,WHOLE_ARRAY,0);

However, the ArrayMaximum function fails because arr_1[] is a string array, and I need to convert it to a numeric array. Please help with solving the conversion from a string array to a numeric one.

Are you doing everything right?

According to the help

You have been answered in the MQL5 questions thread - enable the indicator as a resource, don't know how - start searching for "resource" on the website

Service Desk deals with financial issues, not training
