Andrey Voytenko:

ok. But if you are working with a private channel, use the Channel ID, not the Channel Name.

Hi andrey

Thank you very much first of all for your time and for your article has helped me a lot and I have read all the publications.

Reading between them I have finally been able to work with the "Telegram_Bot_EA" in to MT5.

Trying "Telegram_Signal_EA" in to MT5, I have not managed to send any signal with either "MA" or "MACD" or with a custom indicator.

The compilation works well but does not send an alert or message.However I know that it is well configured since I have been able to work with "Telegram_Bot_EA".

I have reviewed the code both the EA and the telegram.mqh I do not see where the fault may be and I am stuck.The EA( Telegram_Signal_EA) cant be send any text info.

Could you help me?Its same files that original article.

In this forum i see this code but i think its not my problem:

   //+------------------------------------------------------------------+
   int SendMessage(const string _channel_name,
                   const string _text,
                   const bool   _as_HTML=false,
                   const bool   _silently=false)
     {
      //--- check token
      if(m_token==NULL)
         return(ERR_TOKEN_ISEMPTY);

      string name=StringTrim(_channel_name);
      if(StringGetCharacter(name,0)!='@')
         name="@"+name;

      string out;
      string url=StringFormat("%s/bot%s/sendMessage",TELEGRAM_BASE_URL,m_token);
      string params=StringFormat("chat_id=%s&text=%s",name,UrlEncode(_text));
      if(_as_HTML)
         params+="&parse_mode=HTML";
      if(_silently)
         params+="&disable_notification=true";
      //      Print(params);
      int res=PostRequest(out,url,params,WEB_TIMEOUT);
      return(res);
     }

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

 Note:I´m sure that work because "Telegram_Bot_EA" can be run well.

Another one: 

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam)
  {
   if(id==CHARTEVENT_KEYDOWN && 
      lparam=='Q')
     {
         
         bot.SendMessage(InpChannelName,"ee\nAt:100\nDDDD");
     }
  }

Note:i press "Q" in to bot chat or channel chat and dont work....i think if you press the key,bot send you text...right?Well, this option cant work.I dont understand... I dont have any error´s or warnings to compile all mql5 code.

Resume: i like send to telegram text signal(buy/sell) about your example indicators or my custom indicators rules but i dont understant why not work me.

Thank you and nice day.

UPDATE1(solved):

I check logs and get this info:

HL 0 06:24:00.729 Telegram_Signal_EAEVO (DE30,M1) Error: Bad Request

LH 0 06:40:00.916 Telegram_Signal_EAEVO (DE30,M1) {"ok":false,"error_code":400,"description":"Bad Request: chat not found"}

RG 0 06:40:00.916 Telegram_Signal_EAEVO (DE30,M1) Error: Bad Request

KQ 0 07:31:00.442 Telegram_Signal_EAEVO (DE30,M1) {"ok":false,"error_code":400,"description":"Bad Request: chat not found"}

MO 0 07:31:00.442 Telegram_Signal_EAEVO (DE30,M1) Error: Bad Request

I´m add a new father and resolve the last error,  but again cant be send message the bot...

EF    0    12:26:44.372    Telegram_Signal_EAEVO (DE30,H1) NAME_bot: NAMEsignalsbot 

UPDATE2(solved):

I check this link http://usefulmix.com/send-message-telegram-channel-bot-http-api/

In the text :

So we need to make the channel private, however in doing so our above HTTP API call will stop working and this is what trying to prublish a message will look like:

{
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: chat not found"
}

i check with the url sample and get this:

        
ok      false
error_code      404
description     "Not Found"

In common.mqh list this error but i´m very lost with this....I research more.

The "problem" its with a convert token, i write and type this code to test and the bot write me:

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+

//Original code:

// {
// 
//  if(id==CHARTEVENT_KEYDOWN &&   lparam=="Q")
//bot.SendMessage(InpChannelName,"ee\nAt:100\nDDDD");
//}

//Test code:

 {

  
   if(id==CHARTEVENT_KEYDOWN && 
      lparam=="Q")
   
      //--- set token
   bot.Token(InpToken);
    bot.SendMessage("ID CHAT OR USER","ITS A TEST!");

}

Thanks a lot Nguyen Van Tuan,
Now, it works with private channels. Before, my bot was working only in public channels.

Best Regards,

Nguyen Van Tuan:

Hi,

When i have tested with this Library of  Andrey Voytenkoon MT5, It not work well so i have some more simple step. Any people hit same error can try to change like me:

1. Confirm add https://api.telegram.org to Allow WebRequest for listed URL

2. When you using chat_id (like "-1001301234105") instead @channel_name, you will hit some error with this code so i have change it

And now I confirm after i have do two things above, this library work well in MT5.

Thanks Andrey Voytenko again.

[Alejandro FG]

Right!!! Same problem!!!!

Hi, I update metatrader v and compile the code again, but report me a warning:

MT5 5.00 build: 2170 4 / OCT / 2019:

"" Obsolete behavior, calls to hidden methods will be disabled in a future version of the MQL Telegram.mqh compiler ""

The reference call to: " StringReplace "

I am looking for any alternative but for the moment I did not find it. In the future rev ..... any ideas?

Thank you!!

Code:

 //+------------------------------------------------------------------+
   void UserNameFilter( const string username_list)
     {

       //--- parsing
       string text=StringTrim(username_list);
       if (text== "" )
         return ;

       //---
       while ( StringReplace (text, "  " , " " )> 0 );
       StringReplace (text, ";" , " " );
       StringReplace (text, "," , " " );
      

       //---
       string array[];
       int amount= StringSplit (text, ' ' ,array);
