Quote from Rickshaw Man:
As usual index futures rise every night, day session flat. Buy the close sell the open profitable 78% of the time.
I'll give you an opportunity to retract that statement that you've been saying for the last month before I do some actual statistical analysis (which you have not done obviously) and show the ridiculousness of that.
But, some clarification:
* Over what period of time is it 78% profitable?
* Does "profitable" simply mean on a case-by-case basis? In other words, you only care about win percentage, and not about actual profit? So, if I make 1 point 4 days and lose 20 points 1 day, that's okay with you? Just checking if you're looking for overall profitability, or just a strict win percentage.
I'm calling you on this because it's my assertion that nothing consistently over a large enough period of time (for a once-a-day trade, let's call that 6 months to a year) will work. It simply cannot happen. It's the same reason buy and sell programs perform arbitrage, the same reason why the carry trade will not work for very long, the same reason why breakouts fail -- because
the market does not allow risk-free gains. If you saw your neighbor making money every time doing the same thing (buying the close, selling the open), then wouldn't you? Suddenly everyone would do it, and suddenly, it wouldn't work any more. And with such a stupidly simple strategy, it's too obvious that people have not considered it, and determined that it won't work.
That being said, I am only guessing based on logic, sound as it may be, and I'm putting myself out there to be ridiculed by you and anyone else if it's determined that it can be profitable. That's the chance I take I guess.
So what will it be -- retract your premise as being true (or seriously clarify it), or be proven wrong by real analysis?
