Ztrader – if history repeat itself 港股博弈

http://clcheung.wordpress.com/2013/10/04/ztrader-if-history-repeat-itself/

Last year, I’ve posted a cycle theory on HSI : http://clcheung.wordpress.com/2012/09/23/hidden-cycles

 

While I have not adjusted the cycle length as far, here is an updated diagram:

 

 

To make it clearer to see, zoom in a bit :

 

 

It seems the cycle is still in effect. Good news is, if history repeats, HSI has passed the bottom and started a new cycle already. It is on a uptrend.

 

However, even a cycle really exists, the top and bottom of the cycle may be drifted from the predicted time frame by months. As one may expected there usually deep V at the market collapse bottoms, drifted by such a scale means that the cycle is not that useful.

 

But since the cycle length is about to be 368 days, a 92 day moving average can be used as a trend trading signal to capture the major wave:

 

 

But if the market goes higher, the current turnover seems not enough. Either the index goes sideways and MUPI turn strong, or new money flow into HK to support this cycle.

 

You can argue that the historical data is not enough or the recent movement seems not fitting well the cycle lines. I have doubts too. It seems the recent price movement indicates the cycle length is widen a bit.

 

Well, it is a believe it or not theory. Let’s see.

把 WhatsApp 對話記錄 (Chat History) 由 iPhone 轉移到 Android

大部份香港人平均一年多一點（年輕人可能更頻密）就換一次電話，每次轉電話最麻煩的就是數據轉移。如果是同一個操作系統可能還簡單一點，但如果是由iOS 轉到 Android（or vice versa）都幾麻煩。幸好現在相片已經可以通過 USB 或不同類型的 Cloud Service 去備份和還原，抄歌仔在 iOS 就要用 iTunes，但 WhatsApp 的 Chat History 又怎樣處理好呢？

剛剛買了部新的 Android 機，想把 iPhone 上的 WhatsApp Chat History 轉過去。查看 WhatsApp 網頁上的 Official FAQ，它已經明確表明不支持不同作業系統的數據轉換。但世事無絕對，在網上 Google了一下，原來是有辦法的，所以決定試一下並把過程和大家分享。


由於時間關系，我只會把簡要的步驟寫出來：


1) 首先用 iTunes 為 iPhone 做備份到電腦上（（不要加密，也不要用 iCloud!）

2) 下載和安裝 iPhone Backup Extractor

3) 在 Backup Extractor 內，Select Backup -> App View -> WhatsApp Messenger -> All Databases

4) 你會見到 Extract ... ，把它們save 到電腦上（免費版本要等一下才能save）

5) 在電腦上你會見到 3個 sqlite files，把這3個檔案抄到新的 Android 手機上（任何位置都可以）

6) 在 Android 上，首先安裝 WhatsApp （同一個電話號碼），然後再安裝 WazzapMigrator

7) 安裝完成後開啟 WazzapMigrator，根據指示進行轉換（Lite 版本轉換時不包括 media）

8) 轉換完成後要重新安裝WhatsApp ，它就會自動恢復您的對話記錄

9) 大功告成！如果順利完成請給我一個 Like。
