今天随便翻阅，偶尔发现TA有害的证据。和大家分享一下

大千里用BB 很多，这里是俺的发现：

https://en.wikipedia.org/wiki/Bollinger_Bands#cite_note-11

在Effectiveness下， 这么说的：

Analysis of the trades, spanning a decade from 1995 onwards, found no evidence of consistent performance over the standard "buy and hold" approach. The authors did, however, find that a simple reversal of the strategy ("contrarian Bollinger Band") produced positive returns in a variety of markets.

By "the contrarian version", they mean buying when the conventional rule mandates selling, and vice versa。

难怪有人在大千上说，用TA 要反着用！（不知谁说的，肯定是高手）

俺说TA 无用，很多人不服，是真赚到了不服？ 还是梦想破灭而不服呢？

啊哈哈哈。。。。。。。。。。。。。。
