这里是海洋论坛，所以不得不介绍Jim Slomans Ocean trading system。 很多使用过它的人都知道，这是一个相当有 效的交易系统。 "Wow!! Ocean theory is amazing. I would never have thought that such a magnificent order could exist in free flowing, often volatile markets which are affected by so many things. I feel honoured to have a copy of this GREAT GREAT book." —J.R., New Jersey
"I want to thank you again for sharing your marvelous discoveries. After six months of trading with the Ocean software, I can say, unequivocally, that you and Pat have created a masterpiece." —S.C., Virginia
Ocean is not about cycles. Its core is an equation that holds for all markets in all timeframes simultaneously. The equation is too general to be used in a practical way. But equations derived from it, such as the Natural Market Mirror or the Natural Moving Average, can be thought of as providing a fascinating and precise window into the market's own natural analysis of itself. 作者说明了这是一个来源于自然法则的程式，有一些不错的指标可以辅助交易， 在国内很多人并不知道星相与自然周期的关系，这是一个大的缺点，比如著名的RSI指标发名者，目前已经对所谓的技术指标不再推崇，转而研究Delta理论，并取得很好的成绩。所以我们有必要要学习一些高级 的技术分析理论，开阔视野。
This chart of Williams Co. vividly illustrates the power of synergistic signals from the Ocean tools. Note that at the time of the NMC zero hit (from below the zero line), the Ocean Fast MA was below the Ocean Regular MA, supporting the case for a bearish trend. Additionally, prices managed to retrace back to the Regular MA, and in fact were “sandwiched” between the Fast and Regular moving averages. Also, the Ocean NMM ROC indicator (a mathematical derivative of NMM itself, and shown in the bottom pane) had exceeded its upper standard deviation band, indicating that the momentum of the retracement rally was at an extreme and that the stock was due for a reversal. Trade locations where multiple Ocean tools indicate a likely reversal can usually be aggressively traded. This trade then yielded a 6-week decline from over $17 to roughly $5 per share, without prices ever trading above the aggressive stop of the Ocean Fast MA!
