Telegram EOD Alert

Works with Any Long-Only AFL Strategy

Designed Exclusively for Daily Timeframe

This document describes how to automatically run a daily AFL exploration at 6:00 PM IST and send Telegram alerts using OpenAlgo.

This module is intended for Daily timeframe only. Lower timeframes are not supported because they require special alert suppression logic.

1. Telegram Bot Setup (One-Time Process)

This step must be completed before AmiBroker can send alerts to your Telegram.

1.1 Create a Telegram Bot

  1. Open the Telegram app.

  2. Search for “BotFather”.

  3. Send the command:

  1. Choose a bot name and username.

  2. BotFather will respond with:

Save this token.

1.2 Configure the Bot Token in OpenAlgo

  1. Open OpenAlgo in your browser (default http://127.0.0.1:5000).

  2. Go to the Telegram Bot page at /telegram, then open Configuration (/telegram/config).

  3. Paste the Bot Token received from BotFather and click “Save Configuration”.

  4. Return to /telegram and click “Start Bot”.

Your bot is now active. The bot has to stay started: /api/v1/telegram/notify rejects requests with HTTP 409 while the bot is stopped, so a scheduled exploration will run but no alert will be delivered.

1.3 Link Your Telegram Account with OpenAlgo

In Telegram, open your bot and send:

Example:

If successful, the bot will respond confirming the link. Your Telegram account is now authenticated with OpenAlgo and ready to receive alerts.

2. Add the Telegram Exploration Module to Your AFL Strategy

Your strategy must contain valid daily timeframe Buy and Sell signals:

Below your strategy code, insert the Long-Only Daily Telegram Exploration Module.

This module automatically:

  • Detects Buy/Sell signals on the latest daily bar

  • Sends formatted alerts via OpenAlgo when Exploration is executed

The alert format is:

This module is intended for Daily timeframe only.

3. Create an APX (Analysis Settings File)

  1. Open AmiBroker’s Analysis window.

  2. Load your AFL containing Buy/Sell signals and the Telegram module.

  3. Set the following:

  • Apply To: Filter or All Symbols

  • Range: 1 recent day(s)

  • From/To: Today

  • Timeframe: Daily

  1. Click “Explore” to verify signals display as expected.

  2. Save the analysis settings:

Save as:

The APX stores:

  • Formulas

  • Symbol list

  • Date range

  • Exploration settings

4. Create a Batch File (.abb)

  1. Go to:

  1. Click “Insert”.

  2. Select Action: Explore.

  3. Browse and choose your .apx file.

  4. Save the batch as:

This batch file will run exploration automatically.

5. Schedule Automatic Daily Execution at 6 PM IST

  1. Open:

  1. Click “Add Task”.

  2. Select your batch file.

  3. Configure:

  • At specific date/time: 18:00:00

  • Repeat: Daily (Monday to Friday)

  1. Click “OK”.

At the scheduled time, AmiBroker will automatically execute:

  • The batch

  • The exploration

  • The Telegram alert module

  • The alerts will be delivered to your linked Telegram account via OpenAlgo

6. Daily Execution Workflow

Every day at 6 PM IST:

  1. AmiBroker loads the APX

  2. Runs the daily exploration

  3. Detects Buy/Sell signals from today’s daily bar

  4. Sends Telegram alerts via OpenAlgo

  5. No manual intervention is required

This works only on Daily timeframe strategies.

Notes and Restrictions

  1. This module is exclusively designed for Daily timeframe.

  2. Intraday or lower timeframes are not supported, because they require:

    • Bar-level alert deduplication

    • StaticVar suppression

    • Session segmentation

  3. AmiBroker must remain running for Scheduler tasks to execute.

  4. OpenAlgo must remain running for Telegram API to respond.

  5. The Telegram bot must be started in OpenAlgo. If it is stopped, POST /api/v1/telegram/notify returns HTTP 409 and nothing is delivered.

  6. The OpenAlgo Username parameter must match the OpenAlgo account that ran /link in Telegram. If no linked user matches, the API returns HTTP 404.

  7. Telegram Priority is clamped to the range 1 to 10; anything outside it falls back to 5.

  8. Internet connection must remain active.
