Most people never need this page. Every plan includes checks from our servers through our own proxies, with nothing to set up.
A proxy sends a monitor's checks out through a different internet address. Adding your own is for people who want more monitors running from our servers than their plan includes, or who watch a shop that keeps turning our addresses away.
A monitor that runs on our servers through our proxies is called a cloud monitor. Free runs 1 cloud monitor at a time, Standard 10 and Power User 50. One more than that is saved paused until you choose which one runs.
Three kinds of monitor don't count towards the number: one with a proxy group of your own, one that runs in your own browser with the Chrome extension, and Pokemon Center queue alerts.
A line can be ip:port, ip:port:user:pass or user:pass@ip:port, with http:// or socks5:// in front if that is how your provider gives them.
StockWatch spreads a monitor's checks across the group and shows how each proxy is doing: how often it gets through, how quick it is, and how often it has been blocked. The copy button on a group puts the whole list on your clipboard.
