    Is stock trading more an art than a science? The truth is it can be anything you want it to be, so long as you make money. The most effective way for me is to identify a trend. Once identified, I look for the bumps in the road that provide great opportunities to get on board.

    It took me a decade to figure out that success in the stock market is found not in the words of pundits, nor the occult of technical analysis, but in the inherent objectivity of algebra and algorithms.

    I would gladly divulge my intellectual property to you, if you would pay me a fortune.


    What makes this work is that unlike a moving average or a trailing stop, the trend line is calculated in such a way as to minimize whipsaws and maximize elongated trends.


    Speaking of which, I see you are enamored with VXX. I have a trend model for it, but why bother, it appears that simply holding short is a winning trading system, without the angst.
