MA Stochastic 戦略

MA Stochastic は、移動平均のトレンドフィルターとストキャスティクスオシレーターの押し目を組み合わせます。 価格が平均を上回りながら上昇トレンドにあり、ストキャスティクスが売られすぎゾーンに下落したとき、次の上昇転換での買いを準備します。

テストでは平均年間リターンは約151%を示しています。株式市場で最も良いパフォーマンスを発揮します。

ショートトレードは下降トレンドでこのロジックを反映し、ストキャスティクスが買われすぎに達したときにラリーを売ります。

固定パーセントストップが、トレンドが突然反転した場合の大きな損失を防ぎます。

詳細

  • エントリー条件: インジケーターシグナル
  • ロング/ショート: 両方
  • エグジット条件: ストップロスまたは反対シグナル
  • ストップ: はい、パーセントベース
  • デフォルト値:
    • CandleType = 15 minute
    • StopLossPercent = 2
    • MaPeriod = 50
    • StochPeriod = 14
    • StochDPeriod = 3
    • StochOversold = 20
    • StochOverbought = 80 価格がSMAより上なら上昇トレンド、下なら下降トレンドです。上昇トレンドで%KがStochOversoldを下回ると買いを準備し、価格がSMAの上にある間に%Kが次に上昇した足で買います。下降トレンドで%KがStochOverboughtを上回ると売りを準備し、%Kの次の下落で売ります。トレンドを外れると準備は取り消され、反対シグナルでドテンします。
  • フィルター:
