概要

この戦略は,クラシックなMACD指標をベースに,トレンド判断指標,ストップ損失方法,収益方法と組み合わせて,比較的完全なトレンド追跡取引戦略を形成しています.仮想通貨,フォレックス,株式取引の両方に使用できます.

取引の論理

  1. MACD インディケーター

    • FASTLENGTH期間のEMAとSLOWLENGTH期間のEMAの差はMACDヒストグラムを形成する.
    • MACDLENGTH 期間のEMAはMACD線を形成するためにMACDヒストグラムを平らにする.
    • MACDヒストグラムが0軸を交差し,取引シグナルを形成する
  2. トレンドフィルター

    • ADX: 傾向があるかどうかを判断するための平均方向指数
    • MA: 移動平均値,MA の上と下の価格がトレンドを形成する
    • SAR:パラボリック SAR,価格の上下を移動するSARは傾向を示します.
  3. 損失を止める

    • ATR トレイリングストップ: ATR パーセントに基づいてストップ損失を設定する
    • SAR Stop Loss: SAR を後続ストップ損失として使用する.
  4. 利益 を 得る

    • ATR 固定取利益距離: ATR ベースで固定取利益距離を設定する
    • % Take Profit: 利益を得る割合を設定する距離
  5. 定時終了

    • 指定された数のバー後に出口を設定することができます

利点分析

  1. 複数の補助判決

    • トレンド,サポート,レジスタンスの判断は誤った信号を避ける
    • ATR/SAR 停止損失 リスクの管理
  2. 柔軟な構成

    • トレンドフィルタを使用するかどうかを選択する
    • ATR または SAR ストップ損失を選択します.
    • ATR または標準の利益を取ることを選択します
    • パラメーターは設定可能
  3. 差異分析提供

    • 過去の正規/隠れた差異を表示する
    • テキスト 通知 を 提供
  4. 最適化 する の は 簡単

    • 多くの組み込み設定可能なパラメータ
    • 異なるパラメータの組み合わせを簡単にテストする

リスク分析

  1. 誤った 指標 は 損失 を 増加 さ せる

    • 誤ったATR,SARパラメータは,早期ストップ損失を引き起こす可能性があります.
    • 過剰な利得率は早めに利得を上げることがある
  2. トレンドの失敗リスク

    • 傾向指標のパラメータが正しくない場合,判断が誤る可能性があります.
    • ブラック・スワン・イベントはトレンドの失敗を引き起こす可能性があります
  3. タイミングで脱出するリスク

    • 固定期間の退出リスク 損失

オプティマイゼーションの方向性

  1. よりスムーズな停止のためにATR,SARパラメータを調整
  2. トレンド判断を最適化するために異なるMA期間をテストする
  3. 利潤率を上げるため,テスト調整された利潤率
  4. 設定を最適化するために変動指標を組み込む

結論

この戦略は,比較的完全な仮想通貨取引戦略を形成するために,トレンド,ストップ・ロスト,テイク・プロフィート,プルバック識別を包括的に考慮する.MACD指標の利点を組み合わせ,偽取引を避けるためにトレンドフィルタリングを追加する;より良いリスク管理のためにATR/SARストップ・ロスを追加する;プルバック識別は追加の参照を提供します.複数の構成可能なパラメータは簡単にテストおよび最適化できます.全体として,この戦略は仮想通貨戦略研究に優れた例として役立つことができます.
