...thanks for the look; something has definitely changed. Could it be passing the string in '_lopen (string,int)'? Would kernel32.dll be affected? Is MQ standing in the way of calls like this? If so, what about so many other Win32 API functions? If so, MQ is more than silly and there will be *many* unhappy people.

Try using this function (tested it and it should work now - but please let me know)

//------------------------------------------------------------------

//------------------------------------------------------------------

//

//

//

//

//

#define sectorSize 1936

#define HFILE_ERROR -1

void getSuffixPrefix()

{

int fileHandle = FileOpenHistory("symbols.raw",FILE_BIN|FILE_READ);

if (fileHandle == HFILE_ERROR) return;

//

//

//

//

//

prefix=""; suffix="";

for(int i=0;; i++)

{

FileSeek(fileHandle, sectorSize*i, SEEK_SET);

string symbolName = FileReadString(fileHandle,12);

symbolName = StringSubstr(symbolName, 0);

//

//

//

//

//

int pos = StringFind(symbolName,"EURUSD",0);

if (pos > -1)

{

if (pos>0) prefix = StringSubstr(symbolName,0,pos);

if ((pos+6)<StringLen(symbolName)) suffix = StringSubstr(symbolName,(pos+6),0);

break;

}

}

FileClose(fileHandle);

}

Seems that low level file operations (like _lopen) are not allowed any more, but we can use built in file operations (luckily)

Yes!, this works. Though we should add ' if (StringLen(symbolName) != 12) break;' to get out of the loop if using to get symbols list or where the eurusd comparison might fail Thanks

PS Any thoughts about coming up with a 'Forex-TSD' standard for 'new' MT4 files to avoid confusion (at least during the transition)? For example, filename_N.mq4, filename_4.mq4, filename_5.mq4 obviously many ways to go about it. I think it would be a good service to the users/community. I know I've devoted a few brain calories to file management as brokers resist upgrade for as long as possible...hopefully until bugs are worked out. It gets even more interesting when modifications introduce capabilities that are NOT downward compatible (I've seen a few already).

Yes. Those are simple warnings that are not influencing the work of the indicator so it can be used in new metatrader 4 without changes

[adeo]

There we go - the filename could have answered that question before it was asked

The good news is that that indicator is also 100% compatible with the new metatrader 4
