Quote from MSDN on the
CStdioFile::ReadString function: "The CString version of this function
removes the '\n' if present; the LPTSTR version does not."

So, the ReadString function is the culprit in removing the newline
character.

Try something like

void CMyDialog::ReadFile()
{
CStdioFile In;

if (!In.Open("Trade.Dat",CFile::modeRead))
{
    return; //could not open file
}

CString Temp;
strTrade = "";
while (In.ReadString(Temp.GetBuffer(8096), 8096))
{
    Temp.ReleaseBuffer(-1);
    strTrade += Temp;
}
In.Close();

UpdateData(FALSE);
}
