Yesterday, something strange happened - negative oil prices... This is something that apparently never happened in the history of the world.
Analysts are trying to figure out what that means to the economy and I can't stop thinking... did developers design the exchange system to handle this intentionally? Was this part of the requirements? Did admins just watch the line going down and wondered whether that will crash the system? Apparently, it worked just fine. I can't say that about the markets.
