PancakeTrade - Limit orders and more for PancakeSwap on Binance Smart Chain

PancakeTrade helps you create limit orders and more for your BEP-20 tokens that swap against BNB on PancakeSwap. The bot is controlled by Telegram so you can interact from anywhere.

DISCLAIMER

This software is for educational purposes only. Do not risk money which you are afraid to lose. USE THE SOFTWARE AT YOUR OWN RISK. THE AUTHORS AND ALL AFFILIATES ASSUME NO RESPONSIBILITY FOR YOUR TRADING RESULTS.

We strongly recommend you to have coding and Python knowledge. Do not hesitate to read the source code and understand the mechanism of this bot.

Features

The bot provides a lot of convenience trading features including:

• Tokens balance and price shown in status messages
• Price tracking relative to buy transaction
• Ability to make buy and sell limit orders including trailing stop loss
• Automatic smart price selection in case PancakeSwap v1 and v2 LPs are available
• Automatic approval for selling
• Assign emoji to each token to differentiate them easily
• Default slippage set on a token basis for faster order creation
• Chart link for each token

Requirements

In order to use this bot, you will need the following:

• A server or computer that can run the script continuously (linux or macOS, as well as WSL have been tested)
• A Telegram bot token (interact with @BotFather)
• Your Telegram chat ID/user ID (interact with @userinfobot)

If you choose to use the Docker image, you'll just need docker installed, see the section below.

If you choose to run the script with Python, you'll need the following:

• Python version between 3.7.1 and 3.9.x
• Poetry
• Optional: git to clone this repository, you can also download the source from the github website.

Quick Start

Before you start, make sure you have your Telegram Bot token + user ID available. Initiate the chat with your bot on Telegram (click the "Start" button) to initialize the chat ID before you start the bot the first time.

Run the following commands

git clone https://github.com/beeb/pancaketrade.git
cd pancaketrade
poetry install --no-dev
cp user_data/config.example.yml user_data/config.yml

Next, open the config.yml file inside the user_data folder with a text editor and populate the secrets section.

The bot needs your wallet's private key in order to sign and execute orders on your behalf. You can either run the command below and enter your private key in the prompt that will be shown, or you can provide an environment variable named WALLET_PK that will be used by the bot. The private key is not the same as the seed words/mnemonic. You need the 64-characters hexadecimal private key.

Your wallet address will be inferred from the private key and doesn't need to be provided.

Run the bot:

poetry run trade

You will receive a notification in the Telegram chat after entering your private key. You can then start by adding your tokens with the /addtoken chat command.

The other most useful command is the /status command that will display all your tokens and the existing orders.

Configuration file

The script looks for a file named config.yml located inside the user_datafolder by default. You can pass another file path to the trade command as a positional argument.

The only parameter that is not self-explanatory is min_pool_size_bnb. Since PancakeSwap migrated to version 2, some tokens have Liquidity Pairs (LP) on both v1 and v2. As a result, the price might be better for buying or selling on one version versus the other. However, sometimes the LP on a given version has very little liquidity, which means that the price is very volatile. In order to avoid swapping on the version that has little liquidity, the bot checks that at least min_pool_size_bnb is staked in the LP. If that's not the case, the bot will use the other version even if the price is worse.

The update_messages parameter will update the status messages every 30 seconds if set to true. If you have trouble with the inline buttons not working, this means this bot token is not able to update messages anymore. It's unclear what the reason is, but it happened a few times to the developer and testers of this bot. The solution is to create a new bot token and try again, or disable update_messages (not ideal).

---
bsc_rpc: 'https://bsc-dataseed.binance.org:443' # you can use any BSC RPC url you want
min_pool_size_bnb: 25 # PancakeSwap LPs that have less than 25 BNB will not be considered
monitor_interval: 5 # the script will check the token prices with this interval in seconds
update_messages: true # status messages will update periodically to show current values
secrets:
  telegram_token: 'enter_your:bot_token' # enter your Telegram Bot token
  admin_chat_id: 123456 # enter your chat ID/user ID to prevent other users to use the bot

Updating the bot

When a new version is released, if you cloned the repository with git, you can simply perform a git pull on the master branch. After that, run the poetry install --no-dev command again to update dependencies.

Use docker

This bot now gets published as docker images on Docker Hub.

Before you start, make sure you have your Telegram Bot token + user ID available. Initiate the chat with your bot on Telegram (click the "Start" button) to initialize the chat ID before you start the bot the first time.

Steps to use docker:

1. Copy the example docker-compose.example.yml file in this repository, rename it to docker-compose.yml
2. Create a file named .env next to your docker-compose file and insert your private key: WALLET_PK=123abc...
3. Create a user_data folder if it doesn't already exist, and create your config.yml file inside (see previous section).
4. Run the service with docker-compose up -d or docker compose up -d depending on your docker version.

Note: the bot will create a file for the database named pancaketrade.db inside the user_data folder on your local machine. Do not delete or move that file because it holds all your token configurations and orders data. This is the file to back up if you want to move the bot elsewhere, etc.

Run as a service

On systems that support systemd, you can use the included pancaketrade.service file to run this script as a service.

cp pancaketrade.service ~/.config/systemd/user/
# edit the new file in .config/systemd/user with your wallet private key
systemctl --user start pancaketrade.service
systemctl --user enable pancaketrade.service # run at launch
