In this tutorial we will be discussing practical examples of how to send alerts from Amibroker to a Telegram channel using Telegram Bot API
In order to be able to do so, you will have first to:
- Create a Telegram public channel
- Create a Telegram BOT via BotFather
- Set the bot as administrator in your channel
Getting the BOT API key from BotFather in Telgram APP
Provided that you did the above, now you can send a message to your channel by issuing an HTTP GET request to the Telegram BOT API at the following URL:
https://api.telegram.org/bot[BOT_API_KEY]/sendMessage?chat_id=[MY_CHANNEL_NAME]&text=[MY_MESSAGE_TEXT]where:
- BOT_API_KEY is the API Key generated by BotFather when you created your bot
- MY_CHANNEL_NAME is the handle of your channel (e.g. @my_channel_name)
- MY_MESSAGE_TEXT is the message you want to send (URL-encoded)
One can send Telgram Alerts from Amibroker in two different ways
1)Modern Way to access HTTP API using InternetOpenURL functions (Supports Amibroker 6.17 or higher)
2)Using AFL scripting (VBScript) inside the AFL Program (legacy method compatible with most of the versions of Amibroker)
Legacy Method
Using AFL scripting (VBScript)
If you understand Amibroker from a coding perspective it supports AFL scripting host. AFL scripting host is an interface between AFL engine and JScript/VBScript engines (aka. Active Scripting technologies) available as a part of Internet Tools & Technologies platform provided by Microsoft.

if (TelegramAlerts)
{
//code for Telegram alerts to channel
tg.Telegram("This is Telegram Alert from Amibroker");
}//end Telegram alert
_SECTION_END();Modern Method
using InternetOpenURL functions
Code requires Amibroker 6.17 as some of the new AFL functions like InternetClose( handle ) , InternetOpenURL( “url” ) , InternetReadString( handle ) – which is essecial to read from internet resource/http api is available from v6.17 or higher version.

1)Apply the AFL to the chart and over the chart -> right click and select Properties
2)Enter the Telegram Bot API Key and Channel ID as per your requirement
3) Press the Send Alert (Trigger Button)
4)Bingo you are done. You should be able to see the Telegram Alert from Amibroker in your Telegram Channel

Thank you Rajandran. I have learnt many things from this site. I could replicate the technique and able to include it along with the exploration.
