....what? Your logic is truly frightening. Are you saying this is a regularly occurring event and that they deliberately did this? Do you have any idea of the scale and complexity and risk of the code they have deployed? This shit understandably happens. There is no "more people means mistakes don't happen" in any organization on the planet.

We had a once in a blue moon mistake in our billions of lines of code, can you help us out. Other banks are watching and there are plenty of other exchanges to do business with"
