    I’m like not 100% sure what floor traders even do besides pose for reaction photos when the stock market does something. Basically professional mourners but for capitalism.

      They stopped being a thing back in the '00s. Floor trading is all done by algorithms now. Specifically, the High Frequency Trading algorithms, that perpetually scan trading indexes and place orders in anticipation of arbitrage opportunities.

      You’ve got a few people on the floor who function as IT and tweak the algorithms as necessary when they encounter bugs. But that guy is more likely freaking because his API is bugging out than because of any change in equity values.
