To add a push notification alert to the provided MT4 indicator code, you'll need to use the `WebRequest` function in MetaTrader 4. Here's how you can modify the code:

1. At the beginning of the code, add the following lines to include the necessary libraries and define the notification URL:

#import "kernel32.ex_"

int SendNotification(string url);

#import



extern string NotificationURL = ""; // Replace with your notification URL

2. In the `start()` function, add the following code after the `DailyOpen` function call to check for specific conditions and send a notification if the conditions are met:

//+------------------------------------------------------------------+

//| Custom indicator iteration function                               |

//+------------------------------------------------------------------+

int start()

{

    int counted_bars=IndicatorCounted();

    if(counted_bars < 0) return(-1);

    if(counted_bars>0) counted_bars--;

    int lastbar=Bars-counted_bars;

    if(counted_bars==0) lastbar-=1+1;



    DailyOpen(1,lastbar);



    // Check for conditions and send notification

    if(!IsTesting() && !IsVisualMode() && StringLen(NotificationURL) > 0)

    {

        // Your condition to send notification (example)

        if(TodayOpenBuffer[0] > 1.2 * TodayOpenBuffer[1])

        {

            string message = "Significant price move detected.";

            SendNotification(NotificationURL + "?message=" + UrlEncode(message));

        }

    }



    return(0);

}

3. After the `start()` function, add the following functions to handle the notification sending process:

//+------------------------------------------------------------------+

//| Send notification to specified URL                               |

//+------------------------------------------------------------------+

int SendNotification(string url)

{

    char data[], headers[];

    string result[];

    int tmp = StringToCharArray(url, data, 0, StringLen(url)) + 1;

    ResetLastError();



    int res = WebRequest("GET", DoubleToStr(randbyt, 0), data, headers, data, headers, result, headers);



    if(res == -1)

    {

        Print("Send notification failed, error: ", GetLastError());

        return(FALSE);

    }



    return(TRUE);

}



//+------------------------------------------------------------------+

//| Encode string for URL                                            |

//+------------------------------------------------------------------+

string UrlEncode(string str)

{

    static string l_result, l_symbols = " !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~";

    int l_symbols_total = StringLen(l_symbols);

    int l_str_len = StringLen(str);

    int l_result_size = 0;



    for(int i=0; i<l_str_len; i++)

    {

        if(StringFind(l_symbols, StringGetChar(str, i)) >= 0)

        {

            l_result_size++;

        }

        else

        {

            l_result_size += 3;

        }

    }



    l_result = StringRepeat("%", l_result_size);



    for(int i=0, j=0; i<l_str_len; i++)

    {

        int l_sym = StringGetChar(str, i);

        int l_pos = StringFind(l_symbols, CharToString(l_sym));



        if(l_pos >= 0)

        {

            StringSetChar(l_result, j, l_sym);

            j++;

        }

        else

        {

            StringSetChar(l_result, j, '%');

            j++;

            StringSetChar(l_result, j, CharToString(l_sym / 16 + (l_sym / 16 > 9 ? 55 : 48)));

            j++;

            StringSetChar(l_result, j, CharToString(l_sym % 16 + (l_sym % 16 > 9 ? 55 : 48)));

            j++;

        }

    }



    return(l_result);

}



//+------------------------------------------------------------------+

//| Return random byte                                                |

//+------------------------------------------------------------------+

int randbyt()

{

    static int l_seed = 0;

    l_seed = (l_seed * 31415 + 6789) % 65536;

    return(l_seed);

}

4. Replace `"Replace with your notification URL"` with the URL of your push notification service. Make sure to encode any special characters in the URL using the `UrlEncode` function.

With these modifications, the indicator will send a push notification to the specified URL when the condition `TodayOpenBuffer[0] > 1.2 * TodayOpenBuffer[1]` is met (which you can modify according to your requirements). The message sent in the notification will be "Significant price move detected.".
