There is an difference, Expert can access websites, but Indicator nearly can't. Then we should push telegram SendMessage to Expert

Thank you very much, Sir Andrey Voytenko

Andrey Voytenko:

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

Hello Andrey

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!");

}

I read again the general post because one people talk about this.
