Just saw that NYSE got hit with a $9 million fine by the SEC for that 2023 trading disaster back in January. Apparently their systems went haywire and they literally skipped opening auctions for like 2,800 stocks. The craziest part? They didn't even realize what happened for almost 90 minutes. Their primary and backup systems ran at the same time and basically told the exchange 'yeah we already did the auctions' when they hadn't. No written procedures to check if this stuff actually happened either. Market went into chaos mode - trading pauses everywhere, thousands of trades got canceled. Pretty wild that something like this can slip through on an exchange that size. Makes you wonder what other gaps exist in their systems if this one made it through.
