コモディティ・フューチャー・インターテンポラル・ボリンジャー・ヘッジ・ストラテジーの Python バージョン (研究目的のみ)

前述した時間間仲介戦略では,開設・閉じるポジションのヘージング・スプレッドの手動入力が必要です.価格差を判断することはより主観的です.本記事では,以前のヘージング戦略をBOLL指標を使用してポジションを開設・閉じる戦略に変更します.

戦略パラメータ設定:

戦略の枠組みは基本的にコモディティ・フューチャー間の時間間のヘッジ戦略の Python バージョン戦略が実行されているとき,両契約のK線データは得られ,その後価格差はスプレッドを計算するために計算されます.配列は,SPREDのデータとして使用されます.TA.BOLLBollinger Bands を計算する関数です.スプレッドがBollinger Bandの上部レールを超えると,ヘッジされ,下部レールに触ると,操作反対になります.ポジションを保持するときに,ポジションを閉じるために中間レールを触ります.
