看了将近100页,感觉有些难啃,稍微哲了点.真正技术,图表说的不太多.更多是分析原理和谈思维方式与心态.

感觉不止是在说短线交易的心态,还能辐射的更深入

算了,我转述还不如摘录表达的清晰

呵呵,没找到文本版的,我就懒得练打字了吧.真有兴趣的自己下pdf看吧.47.08M(这是个纯扫描的版本,没我看的那个清晰)

…或者是我演绎太多了…?顶多解释成我平时太过抗拒吹嘘人生哲理的扯淡书吧….whatever, 先把这些记着吧

p.s. Jay的音乐还不错,基本算顺耳的

p.p.s. Yahoo对中文的支持还不是一般的糟糕.notepad里存的中文字全成了乱码 :(

p.p.p.s. To: “you know whom I proposed to mention”, 坚持,努力~ ;-)
