• Notifies you once order is closed and trade successfully executed
• Fully usable with buttons - no need to enter commands manually
• Supports all currencies available on Kraken (configurable)
• Change bot settings via bot
• Following Kraken functionality is implemented
  • Create a buy / sell order (type limit)
  • Lookup last trade price for currencies
  • Show all your assets
  • Current market value of assets (one or all)
  • Show / close open orders
  • Sell all assets for current market price
  • Deposit & withdraw
  • Show real-time charts
  • List history of closed orders

Configuration

Before starting up the bot you have to take care of some settings. You need to edit two files:

config.json

This file holds the configuration for your bot. You have to at least edit the values for user_id and bot_token.

• user_id: Your Telegram user ID. The bot will only reply to messages from this user. If you don't know your user ID, send a message to Telegram bot userinfobot and he will reply your ID
• bot_token: The token that identifies your bot. You will get this from Telegram bot BotFather when you create your bot. If you don't know how to register your bot, follow these instructions
• trade_to_currency: The base currency you are using (for example EUR or USD)
• check_trade: If true then every order (already existing or newly created) will be monitored by a job and if the status changes to closed (which means that the trade was successfully executed) you will be notified by a message
• check_trade_time: Time in seconds to check for order status change (see setting check_trade)
• update_url: URL to the latest GitHub version of the script. This is needed for the update functionality. Per default this points to my repository and if you don't have your own repo with some changes then you can use the default value
• update_hash: Hash of the latest version of the script. Please don't change this. Will be set automatically after updating
• update_check: (currently not used) If true, then periodic update-checks (see also option update_time for timespan) are performed. If there is a bot-update available then you will be notified by a message
• update_time: (currently not used) Time in seconds to check for bot-updates. update_check has to be enabled
• send_error: If true, then all errors that happen will trigger a message to the user. If false, only the important errors will be send and timeout errors of background jobs will not be send
• show_access_denied: If true, the owner and the user who tries to access the bot will both be notified. If false, no one will be notified. Set to false if you get spammed with Access denied messages
• used_coins: List of currencies to use in the bot. You can choose from all available currencies at Kraken: XBT, BCH, DASH, EOS, ETC, ETH, GNO, ICN, LTC, MLN, REP, USDT, XDG, XLM, XMR, XRP, ZEC
• coin_charts: Dictionary of all available currencies with their corresponding chart URLs. If you want to add new ones, get the plain URL of the chart, save it with tinyurl.com and add the new URL to the config file
• log_to_file: If true, debug-output to console will be saved in file debug.log

kraken.key

This file holds two keys that are necessary in order to communicate with Kraken. Both keys have to be considered secret and you should be the only one that knows them.

If you don't know where to get / how to generate the keys:

1. Login to Kraken
2. Click on Settings
3. Click on API
4. Click on Generate New Key
5. Enter Telegram-Kraken-Bot in Key Description
6. Enter 4 in Nonce Window (or just use the default value)
7. Select all available permissions at Key Permissions
8. Click on Generate Key

When you have your Kraken API keys, open the file kraken.key and replace some_api_key (first line) with the value of API Key and some_private_key (second line) with the value of Private Key.

Installation

In order to run the bot you need to execute the script telegram_kraken_bot.py. If you don't have any idea where to host it, take a look at Where to host Telegram Bots. Since you have to provide sensitive data (Kraken API keys) to use the bot, i would only host this script on a server that you own. You can also run the script locally on your computer for testing purposes.

Prerequisites

Python version

You have to use Python 3.6 to execute the script (because of enum method auto()). If you would like to use Python 3.4 or 3.5, you have to remove auto from imports and set the values in WorkflowEnum and KeyboardEnum yourself. Python 2.x is not supported.

Needed modules

You need to install the following Python modules first:

pip3.6 install python-telegram-bot -U
pip3.6 install krakenex -U
pip3.6 install requests -U

Installing from requirements.txt

Do the above to install the newest versions of the needed Python modules (recommended) or if you run into issues, install a set of module-versions that is known to work together for sure with:

pip3.6 install -r requirements.txt

Starting up

To start the script, execute

python3.6 telegram_kraken_bot.py &

Usage

If you configured the bot correctly and execute the script, you should get a welcome message from the bot along with the information if you are using the latest version. There should also be a custom keyboard that shows you all the available commands. Click on a button to execute the command or type the command in manually.

Development

I know that it is unusual to have the whole source code in just one file. At some point i should have been switching to object orientation and multiple files but i kind of like the idea to have it all in just one file and object orientation would only blow up the code. This also makes the /update command much simpler :)

Todo

Priority 1

• Add command /history that shows executed trades
• Add command /chart to show TradingView Chart Widget website
• Add command /funding to deposit / withdraw funds
• Add command /alert to be notified once a specified price is reached
• Add possibility to sell all assets immediately to current market value
• Enable to trade every currency that Kraken supports
• Add possibility to change settings via bot

Priority 2

• Optimize code to call Kraken API less often
• Automatically check for updates (configurable timespan & changelog)
• Create webhook-version of this bot

Priority 3

• Add command /stats that shows statistics
• Closed order notifications: Show gain / loss if association between orders possible

Troubleshooting

In case you experience any issues, please take a look at this section to check if it is described here. If not, create an issue on GitHub

• Error Invalid nonce: It might happen pretty often that Kraken replies with this error. If you want to understand what a nonce is, read the Wikipedia article. This error happens mostly if you use different Telegram clients. Maybe you issued some commands on your laptop and then switched to your smartphone? That would be a typical scenario where this might happen. Or you didn't use the bot for a long time. To resolve it, just execute the command again. It should work the second time - meaning you press the keyboard button again. Unfortunately there is not much i can do. The correct behavior would be to have one Kraken API key-pair for one device (one for your smartphone and one for your laptop). Unfortunately there is no way to identify the client. You can play around with the nonce value in your Kraken account (take a look at the settings for the generated key-pair). If you are really annoyed by this then here is what you could try: Create some key-pairs (5 might do it) and then, before you call the Kraken API, randomly choose one of the keys and use it till the next Kraken API call is made.
• Error Service unavailable: If you get this error then because Kraken fucked up again. That happens regularly. It means that their API servers are not available or the performance is degraded because the load on the servers is too high. Nothing you can do here - try again later. If you want to have details on the API server performance, go to Kraken Status.

Disclaimer

I use this bot personally to trade on Kraken so i guess it's kind of stable but if you use it, then you are doing this on your own responsibility !!! I can not be made responsible for lost coins or other stuff that might happen due to some fuckup within the code. Use at your own risk!
