US stock trade (artificial) limits might have existed before but I don’t remember them. You see these in other countries and commodity markets. Limit down. IMO

US stock trade (artificial) limits might have existed before but I don’t remember them. You see these in other countries and commodity markets. Limit down. IMO they cause a faster drop in a down market because you don’t know when you’ll be able to exit. The market can open limit down within seconds. This can continue for weeks.
