この戦略は,一定期間の価格とボリュームの分布を分析することで,ボリュームヒートマップとリアルタイム価格を組み合わせて買い売りシグナルを生成する.戦略は,まず現在の価格と設定された価格範囲のパーセントに基づいていくつかの価格レベルを計算する.その後,過去期間の各価格レベルでの買い売りボリュームを数え,累積的な買い売りボリュームを計算する.ラベルの色は累積的な買い売りボリュームに基づいて決定される.さらに,戦略はリアルタイム価格曲線をプロットする.さらに,戦略はEMAやVWAPなどの指標を組み込み,価格とボリュームとの関係に基づいて買い売りシグナルを生成する.買い条件が満たされ,以前のシグナルが発生していないとき,買い買いシグナルが生成される.販売条件が満たされたとき,または連続した2つの赤いキャンドルが存在し,以前のシグナルが発生していないとき,販売シグナルが生成される.
この戦略は,ボリュームヒートマップ,リアルタイム価格,および複数の技術指標を組み合わせて,特定の基準値を提供することで,購入・売却シグナルを生成する.この戦略の利点は,価格とボリューム分布を直感的に表示し,シグナルを生成するために複数の要因を包括的に考慮する能力にあります.しかし,この戦略にはパラメータ設定の影響,指標の遅延性,トレンド市場への依存などのいくつかの制限とリスクもあります.したがって,実践的な応用では,より多くの指標を導入し,信号条件を最適化し,リスク管理を強化し,戦略の強度と収益性を向上させるなど,戦略のさらなる最適化と改善が必要です.
