I am curious how stock markets worked before the advent of computers. Trading today is so fast, I can’t wrap my head around how it could have worked before computers were involved.

Answer 1

I’m in my 40s, but computers have been common through all my adult life. My mom works in HR. I asked her one time how large companies kept employee records before computers. She said carbon copies in different cities, huge walls of filling cabinets.

… I can’t even imagine this inefficiency.
