> maybe someone can explain why this would be a bad idea, but I'd really like to see a system where if you buy a stock you are not allowed to sell it for a fixed period of time that would be measured in months, and not seconds.

Um, sure. It would be a bad idea for me if I'm not allowed to sell the stock I want to sell as soon as I want it, and it would be a bad idea for somebody willing to buy from me, if they are not allowed to.

Oh, you're asking why it's a bad idea for you? I don't know, maybe it's not. Do you think I should be prohibited from the trades I like because you think it's a bad idea?
