By the way, I didn't notice that this thread is not about options. I meant to reply the other thread. So pardon me.
Quote from NoMoreOptions:
Well directional or non-directional, buy or sell, call or put, and most complex combinations, they do not matter but all lose-lose. You are at disadvantage since the beginning. Your chance is not even closely as high as 50% but far below. Take my advice. Do not waste your leisure time and money in options. If you want to experiment and learn it, that is fine. If you want to bet on the underlying, it is also fine. But forget about betting on options with the wishful thinking that you may make a home run AND/OR make consistent profit. Good luck.
