Need help to convert the code into MT4

Dilchan B M 2021.06.13 18:58

Hello,

I want to print the list of symbols having open orders buy,sell and pending orders. I have a MT5 version of code but could not make it working in MT4.

Would very much appreciate if you can help me to convert this code into MT4 version.

Thanks.

string SyMass[];
bool Find(string aSymbol)
{
int arr = ArraySize(SyMass);
for(int i = 0; i < arr; i++)
if(SyMass[i] == aSymbol)
return false;
if(ArrayResize(SyMass, arr + 1) != -1)
SyMass[arr] = aSymbol;
return true;
}
bool FillSymbols(void)
{
int TotalPositions=PositionsTotal()-1;
for(int i = TotalPositions; i >= 0; i--)
if(Find(PositionGetSymbol(i)) == false)
{
}
int arr = ArraySize(SyMass);
for(int f = 0; f < arr; f++)
{
Print(SyMass[f]);
}
return(true);
}

You should start by reading the MQL4 documentation, especially the trade functions, as it is completely different to MQL5 (e.g. instead of "PositionsTotal", use OrdersTotal).

However, you will have to change the logic of your code, because MT4 handles things differently from MT5.
