Overview

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.

Steps to use docker:

Copy the example docker-compose.example.yml file in this repository, rename it to docker-compose.yml
Create a file named .env next to your docker-compose file and insert your private key: WALLET_PK=123abc...
Create a user_data folder if it doesn't already exist, and create your config.yml file inside (see previous section).
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

Request: Disable PK input every run poetry trade

Every time i'm start this bot it always ask Private key.. and for me this annoying ,, i try to change the code but it failed ,,

i think the best way is to acess .env WALLET_PK as docker do ,,

as in readme.md i have try created .env file with WALLET_PK=MYPK

in root and user_data ,,, the prompt asked for pk is still exist,,,

is this should be tagged as bug?

Different LPs on Pancake

Hi, First of all, nice job on the bot. One question I have is: is it possible to support different LP on the pancake swap? (maybe a silly question) Also, I'm not very sure, but I think for example MTV/BNB and MTV/USDT are different LP for a single coin? (see screen)

Proposal: when you add a coin you can select which LP to use.

Feature Request

I tried to write my own a DeFi bot but I failed because testing the code with BSC testnet was not working. Forking mainnet in Ganache, Hardhat was also problematic. LP pairs on testnets were always giving weird errors.

How do you test your code? Would you like to share your unit tests (if any)?

Add Passphrase when starting the bot.

Add Passphrase when starting the bot.

it would be interesting if the user, when interacting with the bot, was asked for the passphrase of the wallet to initiate transactions..

I understand that when starting the project on linux the passphrase is passed or via the conf file... but the bot could request this information (giving a little more sense of security for those who will use the bot).

Example:

Releases(v0.7.2)

v0.7.2(May 30, 2022)

The price impact calculation was not normalizing token decimals, so it could produce wrong results for tokens that have less or more than 18 decimals. This has been fixed in this release.
Source code(tar.gz)
Source code(zip)
v0.7.1(May 18, 2022)

This small update adds a feature that will warn if the price impact of a transaction is predicted to be high (configurable via max_price_impact, default 5%).

If the price impact is above this value when the order executes, the transaction will be skipped and order removed, to prevent trading at a very unfavorable price.

Before upgrading, add the max_price_impact entry in your config file (see README or example config file).
Source code(tar.gz)
Source code(zip)
v0.7.0(Mar 24, 2022)
This substantial release adds long-await features requested by users.

After pulling this update, please run poetry install --no-dev to upgrade all dependencies!

A new setting price_in_usd allows to display, input and track prices in USD/token instead of BNB/token

All existing order prices will be automatically updated when the bot is restarted after changing this parameter (using current BNB price)

Orders are still buying using BNB, and selling for BNB. Customization of this behavior will come in a later update.

Orders can now be edited with the /editorder command. Price, trailing stop loss callback, amount, gas and slippage can be edited for an existing order.

Codebase has been cleaned up and pre-commit hooks are now available to format code before allowing a commit. Install using pre-commit install after upgrading the dependencies if you wish to contribute to this repository.

Source code(tar.gz)
Source code(zip)
v0.6.2(Jan 25, 2022)
Make sure to run poetry install --no-dev if you upgrade from a previous version.

This version changes the following:

the behaviour when a high gas estimate is returned by the RPC: instead of proceeding with an acceptable gas limit which would likely be exceeded, leading to a failed transaction, the order is now cancelled when gas usage would reach above 2.5M gas units. Gas-expensive tokens should thus be traded manually on pancakeswap to allow for fine-tuning of the gas price.

dependencies have been updated, which removes some warning messages about deprecated features

added support for a .env file in the root directory (same folder as the pyproject.toml file) to define the wallet private key, instead of using other means like prepending it to the poetry command or inserting it in the service file

added chart link for DexScreener

Source code(tar.gz)
Source code(zip)
v0.6.1(Nov 9, 2021)
This version builds up on the last release and adds support for USDT pairs on Binance Smart Chain.

Now, whenever a buy or sell order is triggered, the following swap paths are compared, and the one with the largest output is chosen:

For buying:

BNB -> Token (using BNB liq)

BNB -> BUSD -> Token (using BUSD liq)

BNB -> USDT-> Token (using USDT liq)

For selling:

Token -> BNB (using BNB liq)

Token -> BUSD -> BNB (using BUSD liq)

Token -> USDT -> BNB (using USDT liq)

Source code(tar.gz)
Source code(zip)
v0.6.0(Oct 14, 2021)
This release adds support to trade against both BNB and BUSD liquidity (more tokens could be added easily if needed) via https://github.com/beeb/pancaketrade/pull/25 .

The price displayed in status messages is taken from the largest LP, counted by number of tokens in the pool. It is believed that this represents the most stable price for this token and thus is the better one to use for visual representation. At the moment when the script buys or sells, the price for each of the following swapping paths will be compared, and the best will be selected (which maximizes the output):

For buying:

BNB -> Token (using BNB liq)

BNB -> BUSD -> Token (using BUSD liq)

For selling:

Token -> BNB (using BNB liq)

Token -> BUSD -> BNB (using BUSD liq)

Please note that the script still uses your BNB to buy, and still gives you back BNB when selling. Only the swapping path (which liquidity is used) has changed. When using non-BNB liquidity, the script automatically does 2 swaps in one single transaction, exactly like the official PancakeSwap client does.

Support for PcS v1 has been dropped to keep complexity down.
Source code(tar.gz)
Source code(zip)
v0.5.2(Aug 31, 2021)
This update adds the following:

Each token has now a BSCScan link that shows the token transaction history for your wallet

Dollar value is shown in the confirmation message after a successful sell

Decimal slippage is now supported, with up to 2 digits after the decimal point

Source code(tar.gz)
Source code(zip)
v0.5.1(Aug 4, 2021)
This release tweaks a few mechanics that should improve performance when the network is congested:

Increased default gas offset for "Buy/Sell" (+10.1 gwei) and "Sell all" (+20.1 gwei) commands.

Increased default gas offset for approval (+0.1 gwei), previously was network default which could be very slow these days

Added link to wallet's BSCScan page in the summary message

Removed deprecated PancakeSwap function swapExactETHForTokens and swapExactTokensForETH as they do not respect slippage when token has transaction taxes.

Source code(tar.gz)
Source code(zip)
v0.5.0(Jul 9, 2021)
This release adds the following new features:

Added manual approval command /approve to be used at any time (to approve for selling on pancakeswap). It will use the best pancakeswap version for selling at the time of the command. A button to manually trigger approval also shows when a new unapproved token is added.

Improvements:

The artificial waiting time after approval has been reduced from 10s to 3s. This delay is to ensure the transaction propagated and that a subsequent approval check will return true.

The nonce for a new transaction is checked just before the transaction is sent, minimizing the risk to use the wrong nonce if there was a transaction shortly before.

The gas price gwei value in the new order confirmation message was shown in scientific notation, now it's floating point.

Bugfixes:

Fixed "0e-35" BNB balance value in status messages when the balance is zero tokens.

Source code(tar.gz)
Source code(zip)
v0.4.7(Jul 6, 2021)
This version brings the following changes and improvements:

The bot now supports listing WBNB holdings (special case due to absence of LP), but wrapping/unwrapping is not yet supported

The swapExactETHForTokens method is now preferred over the swapExactETHForTokensSupportingFeeOnTransferTokens if gas estimation works.

The gas limit failsafe has been raised to 2,000,000 gas units to accommodate new contracts with complex reflection schemes

Logging when gas estimation failed is now more verbose and indicates the potential reason being insufficient slippage

Source code(tar.gz)
Source code(zip)
v0.4.6(Jun 28, 2021)
This release improves on some small things and fixes a minor bug:

Added support for Basic HTTP Auth when using a custom RPC URI (see user_data/config.example.yml)

Fixed dex.guru links which did not support URIs without the -bsc suffix anymore

Added link for DEXT (dextools.io)

Normalized amounts display in status messages to have the code markup everywhere (easier to copy-paste on some clients)

Added BNB price in summary status message

Fixed orders' type icon in /removeorder conversation and added list of orders at order selection step.

Source code(tar.gz)
Source code(zip)
v0.4.5(Jun 14, 2021)
This released focused on ironing out a few bugs that were discovered.

Fixed:

A bug was present when the configurable monitor_interval was set to a value not divisible by 5. https://github.com/beeb/pancaketrade/issues/9

The config's RPC-URI validation regex did not accept URIs without a port number https://github.com/beeb/pancaketrade/commit/45a24e270a43ebe5b55442f639a9313fd39c5189

When an token returns a zero price, due to not having a PcS LP or the LP being empty, creating and order would spam messages in the chat every monitor_interval seconds. This message is now only logged in console. https://github.com/beeb/pancaketrade/commit/db5d03d7e58bd48076d2dda9abf715a817edb06e

The prompt for the wallet's private key, when not defined in environment, was displaying the now removed wallet address config item, resulting in a cyclic dependency. This has been fixed. https://github.com/beeb/pancaketrade/commit/08f1b985f2daf7e685140ddf74623e4a75c63833

There was a division by zero error when user edits effective buy price for a token that has zero balance https://github.com/beeb/pancaketrade/commit/2687e8bef20d89b66c9ca42610cdd699f6ce525f

Modified:

The python-telegram-bot library dependency has been upgraded to latest

Added emojis to the buttons for order type selection and display https://github.com/beeb/pancaketrade/issues/4#issuecomment-859256552

v0.4.4(Jun 3, 2021)
This version includes the following changes:

The summary status message now includes the wallet's BNB balance, total balance of tokens in BNB, and the sum of both

The status messages have been optimized to make fewer network requests, thus being overall faster now

The way the bot handles transaction receipts has been improved, to use the event data defined in the ABI for each contract (this is used to extract the amount of received tokens/BNB).

The config file doesn't include the wallet address anymore, as it can be inferred from the private key which is anyway provided. You can remove the wallet item in your config file. This item, as well as bscscan_api_key, are deprecated and will raise an error in version 1.0.0.

v0.4.3(Jun 1, 2021)

This version now adds automatic docker builds. Refer to the Readme for instructions on how to run this bot using docker.

A bug was also fixed, whereby the effective buy price after a transaction was not shown in the token status message until another order was added to that token, or the bot was restarted. This is now fixed.

v0.4.2(Jun 1, 2021)

This version fixes a critical bug where status messages would not update anymore.

Links to Poocoin, Bogged and Dex.Guru charts are now displayed for each token.

v0.4.1(May 31, 2021)
IMPORTANT MIGRATION NOTE

If you are updating from 0.3.x, please note that you need to move your config.yml and pancaketrade.db files inside the new user_data directory before starting the bot. This was done in preparation for the release of docker images.

This version comes with a few very nice changes:

Added missing /sellall command to the commands list dropdown

Prepared files for future docker release, please don't use yet as it's not been thoroughly tested

Approval requests now check proper gas limit estimate before submitting transaction (in the past, a hardcoded value was used)

Revamped /edittoken command to have a branching flow instead of linear.

Added option to manually edit the effective buy price for each token, via the /edittoken command. Can be calculated from BNB amount or directly input as price value (https://github.com/beeb/pancaketrade/issues/2)

Total value of all tokens is shown in the last message of the status command.

v0.3.0(May 26, 2021)

This version adds price tracking to the bot (https://github.com/beeb/pancaketrade/issues/2).

When making a buy order, the effective buy price (after tax) gets saved together with the token record in the database. In the status message, the effective buy price, as well as difference to current price (in percent), is shown, allowing to see if the position increased or decreased since buy.

When a sell order is made, this price is not changed. However, if a second buy order happens, a weighted average between the new effective price and old effective price is calculated and replaces the old price.

v0.2.4(May 23, 2021)

This update and 0.2.3 from earlier today improve and normalize the token amounts rendering.

What's more, BscScan API is no longer needed as the script now uses local default ABIs for all contracts. This should be faster and more reliable. We only use a couple of functions for tokens and these are defined in the BEP-20 token interface so all tokens should have them implemented. This makes it seamless to interact with proxy contracts also.

If you have the bscscan_api_key entry in your config file, you can remove it now.

v0.2.2(May 22, 2021)

The auto-approval process is now smarter. If a buy order is placed, the tokens are first bought, then the wallet is approved for selling. If a sell order is placed while the address is not yet approved, it's mandatory to approve first, before selling.

This is only done once per token and per pancakeswap version. The process is smart and only approves on the version that will be used for selling at the best price (when both versions are available).

Added "Buy/sell now" and "Create order" buttons to the "Token added" confirmation message, for even faster buy after adding a new token.

v0.2.1(May 21, 2021)

There was a bug with the "cancel" button on the list of tokens that would catch all cancel commands for other commands.

v0.2.0(May 21, 2021)
Version 0.2.0 brings a lot of small changes to how interaction works:

Added:

Command to edit token icon and default slippage

Fixed:

Incorrect BNB output after sale due to multiple withdrawals within one function was fixed. Now only considering the last "Withdraw" call.

Added missing order ID in order creation confirmation message

Modified:

Removed 10 or 5 minutes timeout on conversations. Conversations now persist as long as the bot runs. Restart removes all ongoing conversations.

Inline buttons are now only shown on the last status message to make the list more compact

All commands now ask for the token to use in the first step.

After a successful transaction, the order that was deleted in shown before the output amount is displayed. This way, the last message is the transaction outcome.

Red and green icons for orders in the status messages are now displayed next to the order type. A more discreet transaction icon is shown at the start of each order line to indent them

Better instruction when the command /order is used with missing argument

v0.1.6(May 19, 2021)

This version adds a new command /buysell as a shortcut to the various "Buy/sell now..." buttons on each token status message. The command shows a list of buttons with all tokens.

When creating an order, the amount of tokens to sell or BNB to use for buying can be specified in percentage of the balance when using the % symbol as a suffix.

The LP selection code had a problem where tokens with a small amount of liquidity (as defined in the config file) returned a price of zero instead of forcing the use of whatever liquidity is available. This has been fixed.

A new config item update_messages allows to turn on periodical update of status messages (currently every 15 seconds).

v0.1.4(May 19, 2021)
This version adds the /addorder and /address commands.

/addorder: allows to start order creation process for any token. The first prompt asks for which token, the rest of the process is identical to clicking one of the "Create order..." buttons.

/address: used to get the contract address for a token, which needs to be selected in the first prompt. The address can be copied to clipboard by simply clicking/tapping on it on most Telegram clients.

Some UI improvements, orders for a token are now sorted by activation price.

v0.1.3(May 18, 2021)

This version adds the option to input the limit price for an order as a multiple of the current token price.

This is useful when creating orders just after buying, to sell at a given profit target.

Example: the token price is 0.01 BNB per token. The user inputs 2.5x as the limit price. The order will activate when the price is 0.025 BNB per token.

Various improvements to the message formatting.

v0.1.2(May 18, 2021)

This version now correctly handles gas price estimates for swap transactions.

The script now also uses swapExactTokensForETHSupportingFeeOnTransferTokens and the reverse equivalent if possible, and falls back to swapExactTokensForETH if gas price estimation fails.
