So instead of a yes/no confirmation, you force the user to explicitly type what they are doing, i.e. "Sell 610,000 shares of stock X for 1 yen each."
This is similar to how Github forces you to type the name of a repository when you try to delete it.
You can also configure a threshold such that the "hardcore" prompt kicks in only if the system detects that the user is trying to do something unusual, i.e. sell a stock for much cheaper than it is.
