Arsi Vwap Atr戦略

適応型RSI戦略で、買われすぎと売られすぎのレベルがATRまたはVWAPからの乖離に基づいて拡大または縮小します。RSIが適応レベルをクロスした際にポジションを建て、RSIが中間ゾーンに戻った際に決済します。

詳細

  • エントリー条件:
    • ロング: RSI が適応的な売られすぎラインを上抜け
    • ショート: RSI が適応的な買われすぎラインを下抜け
  • ロング/ショート: 両方
  • エグジット条件:
    • RSIが50または反対の適応ラインを再クロス
  • ストップ: StopLossPercent と RiskReward を使用したパーセントベース
  • デフォルト値:
    • RsiLength = 14
    • BaseK = 1m
    • RiskPercent = 2m
    • StopLossPercent = 2.5m
    • RiskReward = 2m
    • SourceOb = ATR
    • SourceOs = ATR
    • AtrLengthOb = 14
    • AtrLengthOs = 14
    • ObMultiplier = 10m
    • OsMultiplier = 10m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame()
  • フィルター:
    • カテゴリ: モメンタム
    • 方向: 両方
    • インジケーター: RSI, ATR, VWAP
    • ストップ: はい
    • 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

/// Adaptive RSI strategy with ATR or VWAP driven levels.
/// The overbought line sits at 50 + 20 * BaseK and the oversold line at 50 - 20 * BaseK, each pushed further out by its
/// multiplier times a volatility measure in percent of price: ATR / close for the "ATR" source, or the distance of the
/// close from the daily VWAP for the "VWAP" source. RSI crossing above the oversold line goes long and crossing below the
/// overbought line goes short, reversing an opposite position. A long closes when RSI crosses above 50 and a short when it
/// crosses below 50. A StopLossPercent stop and a StopLossPercent * RiskReward take-profit protect every position.
