It wouldn't matter would it? The bot makes a whole lot of $1 bids and finds no sellers, life carries on.
For bots that might want to sell the stock this would likely be a large enough jump to trip a circuit breaker.
But really this was a display bug. It's possible some bot is still using 32 bit unsigned ints internally, but it would have to be pretty badly designed since this issue has been obvious and a long time coming.

- nrmitchi 6y agoTIL. Thanks!
- weird-eye-issue 6y agoYeah I can see nothing wrong with this except for stock splits, dividends, etc.
- stu2b50 6y agoYou don't even actually match up buyers and sellers on the public markets anymore for stocks. Individuals (from retail to institutional investors) buy and sell to market makers; later, when settling, market makers will pair up with brokers when clearing the funds. So it'd be up to the market makers to not fuck up and sell at $1. If not, it's their liability.
