Introduction
Telegram isn't just for sending and receiving chat messages. It'south likewise for automating your dialog flow, including work catamenia. Using a Telegram Bot gives yous the ability to bank check prices, query condition, manage trades, and even have a fun conversation. And if you're a serious crypto or forex trader, you can create your own Telegram Bot to manage your order flow.
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 can mind and process letters from a user, too as reply to the user with orders and account data.
Prerequisites
* Metatrader 4 ["MT4"] client and demo account with whatsoever banker.
* Telegram Bot created in your Telegram business relationship. The tutorial How to Create a New Telegram Bot walks you through creating a bot and configuring your MT4 customer.
* Postman Windows application to understand how the Telegram HTTP API works.
Stride 1 - Peeking into Telegram'due south HTTP API with Postman
Before diving into the MT4 EA build, let'south take a peek at how the Telegram HTTP API work, in detail 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 message returned by this office can get crowded very quickly, if the Bot is a fellow member of more than 1 grouping or channel.
Each Bot can too have a private chat with whomever sends a individual message to the Bot.
For example, my Bot belongs to both a channel TradeTitanSignal and a private conversation where I can sent it private messages.
GET https://api.telegram.org/bot**token**/getUpdates The response in JSON format requires some explanation:
* The update_id value represents a sequential number that is assigned to every message regardless of whether the message is from a aqueduct mail service, or a private message, etc.
"update_id": 769794061, "update_id": 769794062, * The update id is followed by the message type, i.e channel_post for a aqueduct message, while a private bulletin begins with message head.
* A channel has a negative chat_id, so we may take to use chat_title to scan for a channel.
"chat": { "id": -1001326947729, "title": "TradeTitanSignal", * A private chat has a positive chat_id, and then nosotros can use sendMessage method to chat to the person.
"conversation": { "id": 902090608, "first_name": "Dennis", * A channel mail has chat_title and chat_username, simply a individual 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", "type": "channel" }, "date": 1569929874, "text": "howdy i'one thousand dennis" * Both channel post and individual message accept update_id, message_id, chat_id, chat_type, date and text. For both channel post and private message, the content tin can exist accessed using text.
"update_id": 769794062, "message": { "message_id": 4, "from": { "id": 902090608, "is_bot": fake, "first_name": "Dennis", "last_name": "Lee", "language_code": "en" }, "conversation": { "id": 902090608, "first_name": "Dennis", "last_name": "Lee", "blazon": "private" }, "date": 1569931564, "text": "hullo" * The response has a limit of 100 letters, but information technology doesn't articulate automatically each time you call the getUpdate method, unless y'all pass information technology an get-go parameter.
* Afterward processing the in a higher place letters, you should call the getUpdates method, but with an starting time value equal to the highest update_id + 1, in this example to a higher place, i.e. 769794062 + 1.
Go https://api.telegram.org/bot**token**/getUpdates?offset=769794063 Nosotros should get an empty response if there are no new messages.
Information technology is important to annotation that calling the getUpdates method again, without the offset value, returns an empty response.
This is because the Telegram API server stores the last offset that we passed as a parameter, so that nosotros don't have to specify the aforementioned offset over again.
{ "ok": true, "upshot": [] } Pace 2 - Creating a New MT4 Expert Counselor
In this section, allow's create a new Expert Advisor ["EA"] in MetaEditor, and name the EA TelegramRecon.mq4.
Get the source lawmaking for the in a higher place MQ4 file.
Showtime, nosotros include the file Telegram.mqh, which provides the class CCustomBot to manage a Telegram Bot.
2d, nosotros declare an input variable TgrToken, which the user must provide. This is the HTTP API token for the Telegram Bot.
Third, we declare two 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 procedure Telegram messages.
(two) The variable intResult is an integer, which holds the result of the bot.GetMe() method. The method returns zilch if successful.
CCustomBot bot; int intResult; Fourth, in the OnInit() office, we call the bot.Token() method and passing it the variable TgrToken.
Then we telephone call the bot.GetMe() method, which returns a zero if successful.
We and so set the Timer to echo every 3 seconds to call the OnTimer() office.
bot.Token(TgrToken); intResult=bot.GetMe(); //--- create timer EventSetTimer(iii); OnTimer(); Finally, in the OnTimer() function, we check the variable intResult. If information technology is a non-cypher value, then nosotros brandish the Error Description on the nautical chart.
Otherwise, if the value of intResult is zero (success), then we brandish the bot Name using the bot.Name() method.
if( intResult!=0 ) { BigComment( "Error: "+GetErrorDescription(intResult) ); return; } BigComment( "Bot name: "+bot.Proper noun() ); Compile the above source code, and you lot should see the TelegramRecon EA in the Navigator under the Skilful Advisors tab.
Step 3 - Running the MT4 EA for Start Time
Before running the EA, we have to add a URL to the Listing of allowed WebRequest URLs in MT4.
Click on menu Tools --> Options (Ctrl+O), and then click on bill of fare tab Skilful Advisors.
Bank check the box Let WebRequest for listed URL, and add together the URL https://api.telegram.org
Click OK push to salve the dialog window.
Next, 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 done every step above correctly, you lot should run into your Bot Name displayed on the nautical chart.
Pace 4 - Edifice a Bot Query Tool
In gild to build a Bot Query Tool, nosotros have to exist able to both transport and process messages to and from a user respectively.
In this department, permit'southward create a new include file in MetaEditor, and proper noun the file CPlusBotRecon.mqh.
Become the source code for the higher up MQH file.
First, we include both the files PlusBotRecon.mqh and Telegram.mqh. The first MQH file is one that nosotros volition create later on that does all the order queries, while the latter MQH contains the form CCustomBot, as previously discussed.
#include <PlusBotRecon.mqh> #include <Telegram.mqh> Second, nosotros declare a new class CPlusBotRecon, which inherits all the methods and information of CCustomBot. In improver, we declare a new public method ProcessMessage().
class CPlusBotRecon: public CCustomBot The method ProcessMessage() checks and parses any messages into commands, prepended by a slash ["/"], that we defined every bit follows:
1. /ordertotal - Return a count of opened orders
ii. /ordertrade - Return ALL opened orders, where EACH lodge includes ticket, symbol, type, lots, openprice, stoploss, takeprofit, and prevticket
3. /orderticket <ticket> - Return an gild by ticket
4. /historytotal - Return a count of history
5. /historyticket <ticket> - Return a history by ticket
half-dozen. /business relationship - Return account number, currency, residuum, equity, margin, freemargin, and profit.
7. /help - Brandish a list of bot commands
Finally, let's create a new include file in MetaEditor, and name the file PlusBotRecon.mqh.
For now, we simply return an empty string in each of our above part.
Let'southward modify our previous EA TelegramRecon.mq4 in MetaEditor.
Detect the following lawmaking into the above MQ4 file and add the line to include file CPlusBotRecon.mqh beneath every bit follows:
#include <Telegram.mqh> #include <CPlusBotRecon.mqh> Next, observe and supervene upon the following lawmaking:
with our inherited form:
Adjacent, find the BigComment code in the OnTimer() function and add two more lines below information technology every bit follows
BigComment("Bot proper name: "+bot.Proper noun() ); bot.GetUpdates(); bot.ProcessMessages(); Compile and attach the EA to any chart, and in the Input dialog window, enter your unique HTTP API token in the Input field TgrToken.
Open up your Telegram app and send a bulletin "/help" to your Telegram Bot. You should become the following response:
Step 5 - Implementing the Bot Commands
The terminal step is to actually implement the empty functions in our include file PlusBotRecon.mqh.
Open up your Telegram app and send a message "/ordertrade" to your Telegram Bot. You should become the following response:
