Telegram bot for displaying cryptocurrencies price

Project description

Telegram Crypto Price Bot

PyPI version Codacy Badge CodeFactor License: MIT

Telegram bot for displaying cryptocurrencies prices and charts based on pyrogram and matplotlib libraries.
Data is retrieved using CoinGecko APIs.
It is possible to show coin information either on demand (by manually calling a command) or periodically using background tasks.
A single bot instance can be used with multiple coins and in multiple groups.
The usage of the bot is restricted to admins, in order to avoid users to flood the chat with price requests.

Setup

Create Telegram app

In order to use the bot, in addition to the bot token you also need an APP ID and hash.
To get them, create an app using the following website: https://my.telegram.org/apps.

Installation

The package requires Python 3, it is not compatible with Python 2.
To install it:

  • Using setuptools:

      python setup.py install
    
  • Using pip:

      pip install telegram_crypto_price_bot
    

To run the bot, edit the configuration file by specifying the API ID/hash and bot token. Then, move to the app folder and run the bot.py script:

cd app
python bot.py

When run with no parameter, conf/config.ini will be the default configuration file (in this way it can be used for different groups).
To specify a different configuration file:

python bot.py -c another_conf.ini
python bot.py --config another_conf.ini

Of course, the app folder can be moved elsewhere if needed.

An example of configuration file is provided in the app/conf folder.
The list of all possible fields that can be set is shown below.

    • COIN_VS: CoinGecko vs_currency
    • flag: true or false
  • /pricebot_task_info: show the list of active price tasks in the current chat

By default:

  • a price task will send chart and price information in the same message. This can be enabled/disabled with the pricebot_task_send_in_same_msg command.
  • a price task will delete the last sent message when sending a new one. This can be enabled/disabled with the pricebot_task_delete_last_msg command.

The task period starts from the specified starting hour (be sure to set the correct time on the VPS), for example:

  • A task period of 8 hours starting from 00:00 will send the message at: 00:00, 08:00 and 16:00
  • A task period of 6 hours starting from 08:00 will send the message at: 08:00, 14:00, 20:00 and 02:00

In case of API errors (e.g. network issues or invalid coin ID) an error message will be shown.

Examples

Show the price of BTC/USD of the last 14 days in the current chat (single call):

/pricebot_get_single bitcoin usd 14

Show the price of ETH/BTC of the last 30 days periodically every 8 hours starting from 10:00 in the current chat:

/pricebot_task_start 8 10 ethereum btc 30

Pause/Resume/Stop the previous task:

/pricebot_task_pause ethereum btc
/pricebot_task_resume ethereum btc
/pricebot_task_stop ethereum btc

Set task so that it sends chart and price information in the same message:

/pricebot_task_send_in_same_msg ethereum btc true

Set task so that it doesn't delete the last sent message:

/pricebot_task_delete_last_msg ethereum btc false

Run the Bot

It'd be better if the bot is an administrator of the group. This is mandatory if it needs to delete the last sent messages.
In order to display prices periodically, the bot shall run 24h/24h so it's suggested to run it on a VPS (there is no performance requirements, so a cheap VPS will suffice).

Test Mode

During test mode, the bot will work as usual but the task period will be applied in minutes instead of hours. This allows to quickly check if it is working.

Translation

The messages sent by the bot on Telegram can be translated into different languages (the default language is English) by providing a custom XML file.
The XML file path is specified in the configuration file (app_lang_file field).
An example XML file in italian is provided in the folder app/lang.
