Here is a simple instruction to add Telegram notifications into your cBot or indicator.

First you need to create your own bot by chatting with BotFather in Telegram

Send /newbot and it will ask desired display name and user name for your new Telegram bot.

From the final message you need Token. Also you need to get chat ID for your new bot to send messages to you.

Go to your bot by clicking link in the final message and send some text.

To get chat ID you need to request latest updates from your bot by entering following URL in your browser:  https://api.telegram.org/bot<TOKEN>/getUpdates
replace <TOKEN> placeholder with your bot token

In response you will get text where you can find chat id
Example: ..."chat":{"id":123,...

Now you have 2 required parameters to send Telegram notifications and you can create cBot or indicator to test it. Telegram messages can be send using simple HTTP request. Here is a helper class that will do it for you.

public class TelegramBot
{
    public string Token { get; private set; }
    public int ChatId { get; private set; }

    public TelegramBot(string token, int chatId)
    {
        UseTls12();
        Token = token;
        ChatId = chatId;
    }

    public bool Send(string message)
    {
        var url = string.Format("https://api.telegram.org/bot{0}/sendMessage?chat_id={1}&text={2}", Token, ChatId, message);
        var request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
        var response = (System.Net.HttpWebResponse)request.GetResponse();
        return response.StatusCode == System.Net.HttpStatusCode.OK;
    }

    public bool Send(string message, params object[] args)
    {
        var formattedMessage = string.Format(message, args);
        return Send(formattedMessage);
    }

    private void UseTls12()
    {
        // Required for SSL/TLS connection with Telegram
        // Will work only on .Net 4.5 or higher
        // Using number to avoid compilation error
        System.Net.ServicePointManager.SecurityProtocol = (System.Net.SecurityProtocolType)3072;
    }
}

 

After adding this class to your cBot or indicator you can send notifications like this:
replace <TOKEN> and <CHAT_ID> with yours

private TelegramBot TelegramBot;

protected override void OnStart()
{
    TelegramBot = new TelegramBot("<TOKEN>", <CHAT_ID>);
    TelegramBot.Send("Started {0} {1}", SymbolName, TimeFrame);
}

 

NOTE: cBot and indicators need extended permission. You need to use Internet or FullAccess permissions:

[Robot(AccessRights = AccessRights.Internet)]
public class NewcBot : Robot

 

I tried this in my bot and I get the following errors : TelegramBot is a type but is used like a variable and the second error is an object reference is required for the non-static field, method, or property. Both points to the lines OnStart

Any suggestions how to fix?

Hi,

You can start cBot/Indicator Timer with 1 second interval, then call the send method inside OnTimer method every one second.

Hi,

You have to add the Telegram bot as an admin on your channel and then you will be able to get a chat ID with it that you can use it to send messages.

Telegram notifications whenever a Trade is Opened or Closed and an update of opened positions every hour

Hello I coded this so that I know when my bot running on a VPS opens or closes a position and I get an update every hour. Do not try to send a message every second, 1) because telegram does not allow 2) keep calm.

You have to grant AccessRights.Internet otherwise the bot won't be able to send messages(just copy paste the code and when prompted you have to click Yes); also, set the timeframe to 5 minutes if you want the updates, otherwise you can set it to 1h timeframe and you will only get the position Opened and Closed message.

Of course you first have to create a Telegram bot and make him joining a group as previously explained from others.

I was able to send telegram messages using the code above. Thank you very much. However, there is a compiler warning - "WebRequest.Create(string) is obsolete ... " . How do I change this to HttpClient Request?

Thank you for answering.

Hi there,

Does your cBot have full access? You can use the tool below to check if there is any issue with your system. If the tool sends telegram messages, then the issue is somewhere in your code
