git clone [email protected]:offish/tf2-express.git
cd tf2-express
pip install -r requirements.txt

Example config:

{
    "bots": [
        {
            "username": "username",
            "password": "password",
            "shared_secret": "Aa11aA1+1aa1aAa1a=",
            "identity_secret": "aA11aaaa/aa11a/aAAa1a1=",
            "options": {
                "use_backpack_tf": true,
                "backpack_tf_token": "token",
                "enable_arbitrage": false,
                "inventory_provider": "steamsupply",
                "inventory_api_key": "mySteamSupplyApiKey",
                "accept_donations": true,
                "decline_trade_hold": true,
                "enable_craft_hats": true,
                "save_trade_offers": true,
                "owners": [
                    "76511111111111111",
                    "76522222222222222"
                ]
            }
        }
    ]
}

# tf2-express/
python main.py # start the bot
python panel.py # start the gui

Now you can visit the GUI at http://127.0.0.1:5000/

Logs will be available under logs/express.log. Level is set to DEBUG, so here you will be able to see every request etc. and more information than is shown in the terminal.

# tf2-express/
git pull
pip install --upgrade -r requirements.txt
# update packages like bptf, tf2-utils, tf2-data and tf2-sku
# which the bot is dependant on

First configure the bot like shown in Setup. Then change the timezone in the Dockerfile, it is set to use Oslo time by default.

make build # will build the tf2-express docker image and install dependencies
make run # will start mongodb and tf2-express

The GUI does not start automatically. To start the GUI run this:

make gui

The GUI will then be available at http://127.0.0.1:5000/

If a craftable hat does not have a specific price in the database, it will be viewed as a Random Craft Hat (SKU: -100;6), if enable_craft_hats is enabled.

Simply open the GUI and add "Random Craft Hat" or -100;6 to the pricelist. Set the buy and sell price to whatever you want. Random Craft Hats cannot get automatic price updates.

"Arbitraging is the process of taking advantage of a price difference between two or more markets". In this case, it is used to buy items from one trade site and sell to another for profit. tf2-express can act on deals from tf2-arbitrage and send or receive offers.

Steam can rate-limit inventory fetch requests if they are called too often. This can be avoided using a third party provider like SteamApis, Steam.Supply, Express-Load or your own. This is especially useful if you are running multiple bots.

# tf2-express/

Every test should succeed except for the version check. The version needs to be incremented to pass this test.
