scprime_price_check

---

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.

Instructions for Linux

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.

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