it saved so many investors from losing money. a great example is a guy who is actually a good trader but only has 10 grand due to the fact that he is young and just starting to save money after graduationg college. even though he has been trading for 5 years the pattern day trade rule prohibits him from daytrading without at least 25k. thank god! i mean the guy has experience so he is sprobably likely to lose money unless he has 25k. 25k means you are automatically deemed a good trader by the sec no matter what your experience level is. it really helps out traders. in fact,an 18 year old kid just out of high school can take all his graduation money and savings and start daytrading with no experience because the sec thinks he has more experience. its a great rule.
