三本足上方リバーサル戦略
このパターンは短い下落後の急速な強気の転換を捉えます。連続する2本の下降ロウソクに続いて、直前のバーの高値を上回って引ける強い上昇ロウソクが必要です。ロジックはオプションでその前に価格が下降していたかどうかをチェックします。
テストでは年平均リターン約85%を示しています。暗号資産市場で最もよく機能します。
戦略は直近の3本のロウソクをメモリに保持します。シーケンスが基準に一致し、下降トレンドフィルターが満たされると、ロングポジションが開かれます。パターンの安値の下のボラティリティストップがトレードのリスクを制限します。
エントリー後、システムはストップが発動するか、反対方向の別のセットアップが現れるまで待ちます。このシンプルなアプローチは売られすぎ状態から急反発しやすい市場に適しています。
詳細
- エントリー条件: より低い安値を伴う2本の弱気ロウソク、その後中央バーの高値を上回って引ける強気ロウソク。
- ロング/ショート: ロングのみ。
- エグジット条件: ストップロスまたは次のパターン。
- ストップ: はい、パターンの安値の下。
- デフォルト値:
CandleType= 15 minuteStopLossPercent= 1RequireDowntrend= trueDowntrendLength= 5
- フィルター:
- カテゴリ: パターン
- 方向: ロングのみ
- インジケーター: Candlestick
- 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
