Is it possible to edit broker's history (.hst) files?

New comment
 

Hello. I try to open broker's .hst files from history/brokerfolder with FileOpenHistory() or FileOpen() functions to see and edit OHLC data, but I can not find any number like open price or any order of candle's data. Can we read inside .hst files?

simple example:

int handle=FileOpenHistory("AUDCAD10080.hst",FILE_BIN|FILE_READ);

while(!FileIsEnding(handle))
      Print(FileReadDouble(handle));
