Amibroker Code to Create a Text File
The below code is the code from the video above and will export a text file of recent candles of a few indices listed in the code.
To adjust it to your needs, be sure to change the FOLDERPATH to your preferred folder where your text file needs to go.
You can also change the symbols to the symbols you want data for. The symbols listed start with $DAX and ends at $XJO

fileName = “C:\\ FOLDERPATH \\OHLC_data.txt”;
fh = fopen(fileName, “w”);
if (fh)
{
fputs(“Symbol,Date,Open,High,Low,Close\n”, fh);
// Define the symbols you want to export data for
Symbols = “$DAX,$FT100,$DJI,$N225,$XJO”;
SetForeign(Symbols);
for (symbolIndex = 0; symbolIndex < StrCount(Symbols, “,”) + 1; symbolIndex++)
{
Symbol = StrExtract(Symbols, symbolIndex);
SetForeign(Symbol);
lastIndex = (BarCount – 1);
line = StrFormat(“%s, %.2f, %.2f, %.2f, %.2f\n”, Symbol, O, H, L, C);
fputs(line, fh);
RestorePriceArrays();
}
fclose(fh);
printf(“Most recent day OHLC data exported to %s successfully.”, fileName);
}
else
{
printf(“Error: Unable to open file for writing.”);
}
