前回の記事では,マルチシンボルのコントラクト・スプレッドモニタリング戦略を共同で設計しました. この記事では,このアイデアをさらに改善していきます. アイデアが実行可能かどうかを確認し,戦略設計を検証するためにOKEX V5シミュレーションボットで実行してみましょう. これらのプロセスは,暗号通貨のプログラム取引および定量取引のプロセスでも経験する必要があります. そこから貴重な経験を蓄積できると信じています.
スポイラー: 戦略が実行されていますが ちょっとワクワクします
戦略の全体的なデザインは,最も単純なアイデアによって実装されています.詳細処理に厳格な要件はありませんが,コードからいくつかのトリックを学ぶことができます. 戦略全体が400行未満なので,読み取るのは退屈ではありません. もちろん,これはテストのためのDEMOにすぎず,結果を確認するためにしばらく実行する必要があります. 私が言いたいのは:現在の戦略は,ポジションを開く場合にのみ成功し,実際にテストおよび検出される閉じるポジションなどのさまざまな状況があります. プログラムデザインのバグは避けられません. したがって,テストとデバッグは非常に重要です!
前回の記事のコードに基づいて 戦略設計に戻ります
上記は追加された機能です.単純に言えば,戦略はポジティブなヘッジのみを設計しました (長期契約のためにショート;短期契約のためにロング).現在,永続契約 (短期) には負の資金調達の割合があります.永続契約で,資金調達の利回りが増加できるか確認してください.
戦略を少しの間 実行させてください.
3日ほどテストされており 波動は良好です
資金の利回りの一部は 次の図で見ることができます
戦略のソースコードは以下のとおり共有されています.
