any financial market's nature is movement. any movement's nature is trend. so,once you shape your own trend judging system,you will find it very easy to get steady profit,and never needn't research,what you need do is just to follow your system. this is my speculating philosophy. of course,it's also very difficult to shape your own proper trend judging system.most of speculators can't achieve this goal. market is the fooliest,bacause itself doesn't know to go which direction.at the same it's the cleverest,because it always make the majority lose by its peculiar way. do you think you can guess what a fool is thinking and what it will do? the only way for most people to get steady profit is following the price trend.if you want to guess the bottom or top of a trend,you will fail sooner or later.few can own the capicity of anticipating and influence like Mr. George Soros. i don't know americans' mind,but i think in any country most speculators make the same mistakes. several days ago i read the book,<Kroll on Futures Trading Strategy>,i am amazed to find our thoughts are so similar,really. in chinese philosophy,thers is a wisdom saying:a really great theory is always very very simple. there is common thought in usa. "keep it simple,stupid".i like Stanley Kroll,so great a speculator.
