This script will get the current price from scpri.me Price TArgets Public and update your host SCP/TB to 0.994x of it. This is because the max change in price in a XA is 0.05, so being 0.06 below it we guarantee to be below the new price when it changes.

Thanks to @vmvelev for his help.

Switch to the user that has permission to change values in spd.

To install it download from the releases page and unzip in your system.

$ cd scprime_price_check

Install de virtual environment

$ python3 -m venv .venv

$ source .venv/bin/activate

Install python dependencies

$ pip install -r requirements.txt

Edit the config.py and change base_cmd to your needs. You need to edit it to match what you would be using to launch spc outside its directory. So something like '/var/lib/spc'. Test the script.

$ python scprime_price_check.py

You will need a cronjob to execute it periodicaly. It must be the crontab of the user who launchs spd.

$ crontab -e

And add a line similar to this one, that will execute the script every hour.

In order to prevent everybody scraping at the same time, you can get an aleatory minute from the following api and use it in the cron job

x = https://www.randomnumberapi.com/api/v1.0/random?min=0&max=59

x * * * * systemd-cat -t "checkprice-cron" /home/daniel/scprime_price_check/.venv/bin/python -u /home/daniel/scprime_price_check/scprime_price_check.py

You will be able to check the journal to see it working like this

$ sudo journalctl -n100|grep checkprice-cron

• Download Python
  • Go to https://www.python.org/downloads/release/python-379/ and download the executable installer for x64 or x86
  • Install it
  • Restart the computer
• Download the repo as a zip file
  • Extract it to your SCPrime folder
  • Rename the folder (repo) to scprime_price_check
• Edit the settings
  • Open the folder
  • Edit the file config.py with notepad
  • Enter the exact directory of your spc.exe - example base_cmd = 'D:\SCPrime\spc.exe'
• Open CMD
  • Go to the folder where the script is (for example cd D:\SCPrime\scprime_price_check)
  • Type python --version. If you get Python 3.x.x everything is ok.
  • Type python -m venv venv (If in the previous step you got Python 2.x.x you should use python3 instead in this command and the next time you call python)
  • Type venv\Scripts\activate.bat
  • At the beginning of the command promt you should now see (venv)
  • Type pip install -r requirements.txt
  • Type the python scprime_price_check.py
  • If you see the script running, you are good to continue
• Create a new text file
  • Name it pricechecker.bat
  • Edit it with notepad
  • The file should contain one line. You have to adapt the path to yours
    • c:\scprime\scprime_price_check\venv\Scripts\python.exe -u c:\scprime\scprime_price_check\scprime_price_check.py
  • And program it to launch periodically. I do it every hour.
