I lost a shit ton of money at the firm where I work right now almost a year ago. I wrote software that began issuing trades outside of where it was expected to and did not stop. In a panic, I forced the server it was running on to terminate its process but trades were still open in the market. They had to be manually closed. I feel sick to my stomach even writing this right now, that hour I was trying to fix the problems sticks out as the worst moment in my life. I am glad whoever wrote this can be so nonchalant about it, if you have a strategy for forgetting I would love to hear it.
