Introduction
Telegram isn't simply for sending and receiving chat messages. It's also for automating your dialog period, including piece of work catamenia. Using a Telegram Bot gives you the ability to check prices, query status, manage trades, and even have a fun chat.

In this tutorial you'll use a Telegram Bot to query your orders on a Metatrader 4 account. You'll create a Telegram Bot ["bot"], build an Expert Advisor ["EA"] that tin heed and process messages from a user, as well every bit respond to the user with orders and account data.
Prerequisites
* Metatrader 4 ["MT4"] client and demo account with any broker.
* Telegram Bot created in your Telegram account. The tutorial How to Create a New Telegram Bot walks you through creating a bot and configuring your MT4 customer.
* Postman Windows application to sympathize how the Telegram HTTP API works.
Step 1 - Peeking into Telegram's HTTP API with Postman
Before diving into the MT4 EA build, allow'due south take a peek at how the Telegram HTTP API work, in particular the getUpdates method, with the Postman app.
The getUpdates method returns messages from all channels, groups, and chats that the Bot is a member of.
In other words, the JSON bulletin returned by this function tin get crowded very apace, if the Bot is a member of more ane group or aqueduct.
Each Bot can too have a private chat with whomever sends a private message to the Bot.
For example, my Bot belongs to both a channel TradeTitanSignal and a private chat where I can sent it private messages.
Get https://api.telegram.org/bot**token**/getUpdates The response in JSON format requires some caption:
* The update_id value represents a sequential number that is assigned to every message regardless of whether the bulletin is from a channel mail, or a private message, etc.
"update_id": 769794061, "update_id": 769794062, * The update id is followed past the message type, i.due east channel_post for a channel bulletin, while a private message begins with message head.
* A aqueduct has a negative chat_id, so we may take to use chat_title to scan for a channel.
"chat": { "id": -1001326947729, "championship": "TradeTitanSignal", * A private chat has a positive chat_id, so we tin use sendMessage method to conversation to the person.
"chat": { "id": 902090608, "first_name": "Dennis", * A channel mail has chat_title and chat_username, but a private message has from_is_bot, from_first_name, from_last_name, chat_first_name, and chat_last_name.
"update_id": 769794061, "channel_post": { "message_id": 4, "conversation": { "id": -1001326947729, "championship": "TradeTitanSignal", "username": "tradetitansignal", "blazon": "aqueduct" }, "date": 1569929874, "text": "hello i'm dennis" * Both channel mail service and individual message have update_id, message_id, chat_id, chat_type, date and text. For both channel post and private bulletin, the content can be accessed using text.
"update_id": 769794062, "message": { "message_id": iv, "from": { "id": 902090608, "is_bot": false, "first_name": "Dennis", "last_name": "Lee", "language_code": "en" }, "chat": { "id": 902090608, "first_name": "Dennis", "last_name": "Lee", "type": "private" }, "appointment": 1569931564, "text": "hello" * The response has a limit of 100 messages, but it doesn't clear automatically each time yous call the getUpdate method, unless y'all pass it an offset parameter.
* After processing the higher up letters, y'all should call the getUpdates method, but with an offset value equal to the highest update_id + 1, in this example above, i.e. 769794062 + 1.
GET https://api.telegram.org/bot**token**/getUpdates?offset=769794063 We should get an empty response if in that location are no new messages.
It is of import to notation that calling the getUpdates method once more, without the commencement value, returns an empty response.
This is considering the Telegram API server stores the concluding beginning that we passed as a parameter, so that we don't have to specify the same get-go again.
{ "ok": truthful, "result": [] } Step two - Creating a New MT4 Proficient Advisor
In this section, let'southward create a new Expert Advisor ["EA"] in MetaEditor, and name the EA TelegramRecon.mq4.
Get the source code for the in a higher place MQ4 file.
Offset, nosotros include the file Telegram.mqh, which provides the grade CCustomBot to manage a Telegram Bot.
Second, we declare an input variable TgrToken, which the user must provide. This is the HTTP API token for the Telegram Bot.
3rd, nosotros declare 2 global variables:
(1) The variable bot is of type CCustomBot, which is a class defined in Telegram.mqh. This bot is used to ship and process Telegram messages.
(2) The variable intResult is an integer, which holds the outcome of the bot.GetMe() method. The method returns zero if successful.
CCustomBot bot; int intResult; Quaternary, in the OnInit() function, we phone call the bot.Token() method and passing it the variable TgrToken.
And so nosotros call the bot.GetMe() method, which returns a zero if successful.
We then prepare the Timer to repeat every 3 seconds to call the OnTimer() role.
bot.Token(TgrToken); intResult=bot.GetMe(); //--- create timer EventSetTimer(3); OnTimer(); Finally, in the OnTimer() office, we check the variable intResult. If it is a non-zero value, then we display the Error Clarification on the chart.
Otherwise, if the value of intResult is null (success), then we display the bot Proper name using the bot.Proper noun() method.
if( intResult!=0 ) { BigComment( "Error: "+GetErrorDescription(intResult) ); return; } BigComment( "Bot name: "+bot.Name() ); Compile the above source code, and you lot should come across the TelegramRecon EA in the Navigator under the Expert Advisors tab.
Step three - Running the MT4 EA for Starting time Time
Before running the EA, we have to add a URL to the List of immune WebRequest URLs in MT4.
Click on menu Tools --> Options (Ctrl+O), and then click on carte tab Expert Advisors.
Check the box Allow WebRequest for listed URL, and add together the URL https://api.telegram.org
Click OK button to save the dialog window.
Side by side, attach the EA to whatever chart, and in the Input dialog window, enter your unique HTTP API token in the Input field TgrToken.
If you had washed every step above correctly, y'all should come across your Bot Name displayed on the chart.
Step 4 - Edifice a Bot Query Tool
In lodge to build a Bot Query Tool, we have to be able to both send and process messages to and from a user respectively.
In this section, permit's create a new include file in MetaEditor, and name the file CPlusBotRecon.mqh.
Get the source lawmaking for the higher up MQH file.
First, we include both the files PlusBotRecon.mqh and Telegram.mqh. The first MQH file is one that we will create later that does all the gild queries, while the latter MQH contains the class CCustomBot, as previously discussed.
#include <PlusBotRecon.mqh> #include <Telegram.mqh> Second, we declare a new grade CPlusBotRecon, which inherits all the methods and data of CCustomBot. In addition, nosotros declare a new public method ProcessMessage().
course CPlusBotRecon: public CCustomBot The method ProcessMessage() checks and parses any messages into commands, prepended by a slash ["/"], that we divers as follows:
1. /ordertotal - Return a count of opened orders
ii. /ordertrade - Return ALL opened orders, where EACH order includes ticket, symbol, blazon, lots, openprice, stoploss, takeprofit, and prevticket
3. /orderticket <ticket> - Return an order past ticket
4. /historytotal - Return a count of history
5. /historyticket <ticket> - Render a history by ticket
6. /account - Return account number, currency, balance, equity, margin, freemargin, and profit.
7. /help - Display a list of bot commands
Finally, let's create a new include file in MetaEditor, and proper name the file PlusBotRecon.mqh.
For at present, we but return an empty cord in each of our above function.
Let's modify our previous EA TelegramRecon.mq4 in MetaEditor.
Find the following lawmaking into the in a higher place MQ4 file and add the line to include file CPlusBotRecon.mqh below as follows:
#include <Telegram.mqh> #include <CPlusBotRecon.mqh> Adjacent, notice and replace the following code:
with our inherited form:
Adjacent, find the BigComment lawmaking in the OnTimer() function and add together 2 more than lines beneath it as follows
BigComment("Bot proper name: "+bot.Proper name() ); bot.GetUpdates(); bot.ProcessMessages(); Compile and attach the EA to any nautical chart, and in the Input dialog window, enter your unique HTTP API token in the Input field TgrToken.
Open your Telegram app and send a message "/help" to your Telegram Bot. You should get the post-obit response:
Stride 5 - Implementing the Bot Commands
The concluding pace is to actually implement the empty functions in our include file PlusBotRecon.mqh.
Open your Telegram app and transport a message "/ordertrade" to your Telegram Bot. You should get the following response:
