[StakeMachine] Trading infrastructure and simple market making bot for Bitshares | OpenSource Bot for BitShares

xeroc (70)in #bitshares • 9 years ago (edited)

I am proud to now publicly announce the first release of StakeMachine.

What is it?

It is a Python tool that offers:

a unified framework for writing bots for the DEX
a simple market making strategy
the liquidity-providing strategy developed by @mauritso
more strategies to come soon.

Simple Market Making

A simple market making strategy (i.e. providing liquidity) works as follows:

Get the last price for your market
Place a buy order at last price * 95%
Place a sell order at last price * 105%
Wait for any of the two orders to get filled
Cancel the other order
Go to 1.

This strategy is very simple and tries to makes a profit from the spread. The more volatile a market is, the more profit it will (probably) make you.

Usage

Requirements

python 3

Installation

git clone https://github.com/xeroc/stakemachine
cd stakemachine
python3 setup.py install --user -r requirements.txt

Configuration

There is an example YAML formatted configuration file called config-example.yml.
The general configuration looks like this

witness_url: "wss://bitshares.openledger.info/ws"
prefix: "BTS"
safe_mode: True
account: "<accountname>"
wif: "<active-private-key-for-account>"
market_separator: ":"

bots:
    MakerWall:
        module: "stakemachine.strategies.maker"
        bot: "MakerSellBuyWalls"
        markets:
            - "USD:BTS"
        target_price: "last"
        target_price_offset_percentage: 1
        spread_percentage: 5
        volume_percentage: 50
        symmetric_sides: True
        only_buy: False
        only_sell: False

Advanced Settings

As you can see, the idea is to

Allow different strategies to be added easily
Different parameters for different bots
Multiple bots in parallel

bots:
    MakerWallBitAssets:
        module: "stakemachine.strategies.maker"
        bot: "MakerSellBuyWalls"
        markets:
            - "USD:BTS"
            - "GOLD:BTS"
        target_price: "last"
        target_price_offset_percentage: 1
        spread_percentage: 5
        volume_percentage: 50
        symmetric_sides: True
        only_buy: False
        only_sell: False

    MakerWallBTCBridge5:
        module: "stakemachine.strategies.maker"
        bot: "MakerSellBuyWalls"
        markets:
            - "OPEN.BTC:BTC"
            - "OPEN.BTC:TRADE.BTC"
            - "TRADE.BTC:BTC"
        target_price: 1.0
        target_price_offset_percentage: 0
        spread_percentage: 5
        volume_percentage: 50
        symmetric_sides: True
        only_buy: False
        only_sell: False

    MakerWallBTCBridge10:
        module: "stakemachine.strategies.maker"
        bot: "MakerSellBuyWalls"
        markets:
            - "OPEN.BTC:BTC"
            - "OPEN.BTC:TRADE.BTC"
            - "TRADE.BTC:BTC"
        target_price: 1.0
        target_price_offset_percentage: 0
        spread_percentage: 10
        volume_percentage: 50
        symmetric_sides: True
        only_buy: False
        only_sell: False

Running the bot

Once the configuration is done, you can run your bot (with safe_mode on) using

stakemachine -c config.yml once

stakemachine -c config.yml run

Roadmap

Extend the python-graphene library to allow

Core Exchange Rate tracking
Refilling of Fee Pools
More trading strategies (heuristic, EMA-crossings, etc.)

So, the liquidity-providing strategy is other software that base on your library?
As i understand it need cli_wallet and your not !?

It's a strategy that uses @xeroc 's bot infrastructure combined with deployment/automatic registration scripts.
In StakeMachine the strategy is updated to work without cli_wallet, those changes (and more) will be implemented in the next release of LiqBot.

I wouldn't claim this makes a profit for sure .. but the strategy is easy enough for people to understand it makes sense and may make a profit

Sorry that this question may not directly related to stakemachine. Can python-graphene be run on Windows with python3 installed?

Technically it should also work on Windows, however, I don't have a windows machine around so I cannot check it.

Hey @xeroc ! I’ve recently been trying to get stakemachine working but am having some difficulty. I know you mentioned you were making some changes with it... are these changes still in progress? I’ve used your stakemachine pdf you posted a couple months ago to copy the walls config but still can’t get the walls to work. I posted on GitHub. Anyway, if you have any additional guidance or documentation that could help I would greatly appreciate it. I’m new to both Ubuntu and python but willing to put in some work. Thanks
