Well they shouldn't be gloating about their ability to exercise thereby leaving thousands on the table.
Yeah... You can tell someone they're stupid, or you can let them, realize it. If you just tell them, they will get defensive and not learn. Losing money is a great way to learn, but it doesn't work when people don't realize they left money on the table. True, but we all have to start somewhere. I think if we expect everyone to do all the research before they start trading, they won't ever get started.
