私が必要とするのは、各企業の追加のセクター列を持つ基本的な株データを持つCVSファイルだけです。ウィキペディアのセクターやテロップを入手するのは問題ありません。Quandlリクエストをフォーマットできますか？
Google/Yahooのデータはもう使用したくないので、私はQuandlを使用しようとしました。私は最近、それに基づいていくつかのテクニカルインジケータを作ったので、それは素晴らしいと思いました。エラー。
私はそれが私の要求をフォーマットすることができればまだ疑問があるので、私は問題があると仮定しますが、それを動作させる方法を考え出すことはできません。
ご迷惑をおかけして申し訳ありませんが、ありがとうございます。

エラー。
