Yeah, please fuck off with the pit dinosaur analogy for this specific circumstance - this is a universal transcendent malady. FWIW, I have personally seen a trader lose $4.4M in one day “cannonballing” the market. On the screen. Totally electronic. In 2006. Interest rates. Russian. Shared office in CME building. 32” screens with quad card running TT combines with his obvious outbursts of angst so yeah it was quite obvious. Frantically wiring money. Personal visits from FCM harried Risk Manager. A trader can actually be MORE stupid on the screen as compared to the pit. Speed and accessibility insures that.
