Question about something I saw in the videos

[iceman21]

When I was watching the currencies video, I saw that Neil had several 'signoff' history events (complex, high performance , etc). What could these be used for when making and keeping track of currencies?

I thought about it and came up with a blank, unless you are an instructor, but even then I am still coming up with a blank as how to implement them.

Any ideas?

Thanks
