Free version is pretty limited as far as 140 free checks so instead of every minute should do every 3-6 hours.
In fact, https://visualping.io/ is actually a better website IMO, longer check interval for free version but a little more advanced and able to navigate pages as well as option to use basic proxy when the website blocks them (i.e otcmarkets.com and sken.io)
I just started messing with the free versions of these sites, so if anyone has anything better please share.
I know all seeing eye is very nice for certain stocks, not sure where people get it though(??)
