Williams %Rブレイクアウト戦略
この戦略はWilliams %Rを歴史的平均と比較して観察することでモメンタムの爆発を探します。オシレーターが典型的な読み取り値をはるかに超えると、強い動きの始まりを示す可能性があります。
テストでは平均年間リターンが約91%であることが示されています。株式市場で最も良いパフォーマンスを発揮します。
%Rが平均値にMultiplier倍の推定標準偏差を足した値を上回ったときにロングポジションを開きます。%Rが平均値から同じ乗数を引いた値を下回ったときにショートポジションを取ります。%Rが平均値に向かって戻るか、ストップロスに達したら取引を決済します。
このアプローチは新興トレンドへの早期参加を望むブレイクアウトトレーダー向けです。ポジションリスクはエントリー価格に基づくパーセンテージストップで管理されます。
詳細
- エントリー条件:
- ロング: %R > Avg + Multiplier * StdDev
- ショート: %R < Avg - Multiplier * StdDev
- ロング/ショート: 両方。
- エグジット条件:
- ロング: %R < Avg のときに決済
- ショート: %R > Avg のときに決済
- ストップ: あり、パーセントストップロス。
- デフォルト値:
WilliamsRPeriod= 14AvgPeriod= 20Multiplier= 2StopLossPercent= 2CandleType= TimeSpan.FromMinutes(5) AvgとStdDevは現在値を含む直近AvgPeriod個の%Rの平均と標準偏差です。 ストップはエントリー価格の固定StopLossPercentで、ローソク足の間も監視されます。0で無効になります。 保有ポジションと逆方向のエントリーシグナルはドテンになります。
- フィルター:
- カテゴリ: ブレイクアウト
- 方向: 両方
- インジケーター: Williams %R
- ストップ: あり
- 複雑さ: 中級
- 時間軸: イントラデイ
- 季節性: いいえ
- ニューラルネットワーク: いいえ
- ダイバージェンス: いいえ
- リスクレベル: 中
