"It should be illegal and the scoundrels should be put in jail."
What should be illegal? Stop loss orders?
Maybe I don't understand the process: An investor, out of a concern that a share price will fall below a certain price, places an order to sell their shares if it ever gets to that price.
You want it to be illegal for investors to do that?
