從 SEC 的 EDGAR 定期下載所有新的 10-K 文件的最有效方法是什麼？
我發現這個網站使用 perl 腳本來下載所有文件。它指出：“有 200K+ 10-K（和等量的）文件，這將需要相當多的硬碟空間和時間來下載。SEC 更喜歡在‘安靜時間’（即正常交易時間之外）進行批量下載。 "
有沒有比向 SEC 的伺服器發出請求以獲取此資訊更好的方法？
10-K - 僅歷史基本面
如果您只對 10-Ks 的基本面（損益表、資產負債表、現金流量表）感興趣，那麼您可以使用提供商eodhistoricaldata.com。我是付費客戶，每天都使用他們的 API。訪問 37K 股票（全球）、6K ETF 和 20K 共同基金的基本面價格為每月 10 美元。
你可以使用
getFundamentals(ticker)庫提供的方法eodhistoricaldata-api（https://www.npmjs.com/package/eodhistoricaldata-api），或者直接訪問他們的 RESTful API。您可以通過程式方式訪問 API，而無需一次下載所有報告。
API 返回 JSON 數據，例如：

如果您需要實時訪問 10-K 文件，我建議
sec-api( https://www.npmjs.com/package/sec-api )。它提供了一個 websocket（實時）通道。一旦在 sec.gov EDGAR 上發布了新文件，圖書館就會觸發一個事件，並返回有關新文件的資訊，如下所示（JSON 格式）：{ companyName: 'WALT DISNEY CO/ (0001001039) (Issuer)', cik: '0001001039', type: '10-K', description: 'FORM 10-K', linkToFilingDetails: 'https://www.sec.gov/...', linkToHtmlAnnouncement: 'https://www.sec.gov/...', linkToXbrl: 'https://www.sec.gov/...', announcedAt: '2018-12-21T20:02:07-05:00' }該庫適用於伺服器端（例如 Node.js）和客戶端（例如 React、React Native、Angular、Vue）JavaScript。
簡單的 Node.js 實現：
const api = require('sec-api')(); api.on('filing', filing => console.log(filing));
我在 python 中為 EDGAR 編寫了一個數據探勘包。它接受股票程式碼列表作為輸入，因此您無需為每家公司下載每 10-k 行情。只是你想要的。希望能幫助到你！
