5 EMA 戦略

5 EMA戦略は、5期間EMAの完全に下または上でクローズするローソク足をマークします。価格がブロックウィンドウ外で3バー以内にそのシグナルローソク足の極値をブレイクした場合、ブレイクアウト方向にエントリーします。ターゲットはユーザー定義のリスク・リワード比に基づき、特定の時刻に強制的に取引を閉じることができます。

詳細

  • エントリー条件:
    • ローソク足の終値と高値がEMAより下 → ロング準備；3バー以内にシグナルの高値を上抜けたら買い。
    • ローソク足の終値と安値がEMAより上 → ショート準備；3バー以内にシグナルの安値を下抜けたら売り。
  • ロング/ショート: 両方。
  • エグジット条件:
    • シグナルローソク足の反対側の極値にストップ。
    • TargetRR × リスクのターゲット。
    • カスタム時刻でのオプション出口 (ExitHour, ExitMinute)。
  • ストップ: はい。
  • デフォルト値:
    • EmaLength = 5
    • TargetRR = 3.0
    • ExitHour = 15, ExitMinute = 30
    • BlockStartHour = 15, BlockStartMinute = 0
    • BlockEndHour = 15, BlockEndMinute = 30
  • フィルター:
    • カテゴリ: ブレイクアウト
    • 方向: ロング/ショート
    • インジケーター: EMA
    • ストップ: はい
    • 複雑さ: 低
    • 時間軸: 5分
    • 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
