Halting only happens for fifteen minutes. It's meant to be a speed bump, an opportunity to assess, "wait, do I really want to sell right now?" If the market drops a lot, they'll halt for the day. Gives leaders a chance to make adjustments.

Are you referring to automated trading? How can someone sell without assessing whether they want to sell? Isn't that a contradiction?

For example, if a grocery store is normally open, and I go there to buy groceries only to found out they're closed... I still need groceries. I would just be forced to wait until they're open or go get them from somewhere else. With that reasoning, I would expect halting trades to encourage capital flight to exchanges with liquidity and predictable operation. People prefer to shop at grocery stores that have predictable hours and stocked shelves.

Maybe but that assumed that what your haulting isn't just an algorithm set by someone...which is almost always is. The algorithm will just continue after the 15m to do what it was doing previously.
