Table of Contents
之前初步篩選找準死魚一直是 Yahoo 股票健檢一頁一頁開來選,
隨著候選標的越來越多有點慢了,
這幾天寫了個輔助工具,
請搭配死魚挑撿買賣流程使用
https://www.ptt.cc/bbs/Stock/M.1505368718.A.912.html
原始碼 (會持續更新):
github gist 跟估狗都不能用了, 再換地方貼
https://jsfiddle.net/f1q4y2wc/
使用方式
1. 以 Chrome 連到 mis.twse 的頁面, 如
http://mis.twse.com.tw/stock/fibest.jsp?stock=6024
2. 按 F12 開啟開發人員工具
3. 點到開發人員工具中的 Console 標籤
4. 將所有原始碼複製貼到 Console 中按 Enter
然後畫面會變全白, 稍等約 60 秒後就會顯示結果
因為目前一次最多抓 50 筆, 且每一次之間會隔 5 秒
(為了減低對伺服器的負擔, 不然被想方法防堵就更難抓了)
編輯資料
可自行依需求編輯 targets 內容,
舉例
'XXXX': ['ABC', 17.7, [12, 25], [], 2,
{'comments': '低價區存 過合理價出', 'suffix': 'TWO'}],
XXXX 是股號, ABC 是股名,
17.7 是存股價, 12 及 25 是區間範圍,
接著那個空的 [] 沒用到, 是記錄已買成交價,
2 則是評價數字, 個人覺得越穩越可靠的數字越大,
(參見 https://www.ptt.cc/bbs/Stock/M.1505368718.A.912.html )
最後的 comments 是當 memo 用,
suffix 則是用來區分上市跟上櫃
只有上櫃的需要加
其它注意事項
選出的只是代表 "可能" 在低檔,
但有可能真的公司變差, 或者大環境對公司不利,
或者取得的股價有誤, 或者我區間沒取好等等,
務必再自行確認基本面及股價等細節
從 twse 抓資料不是很穩定, 有時會沒回應,
也有一些資料有缺 (如 神通),
就再自行重跑或單獨查吧 @@
