Edit the strings your-proxy-or-server with the ip or hostname of your proxy or Zabbix server,
Edit the strings your-host with the name of your host as listed in the Zabbix Server GUI

This script is using zabbix_sender.exe to push data to 3 Zabbix trapper items configured for your host, named costprice, sellprice and profit. All three items are floats.
