この戦略は,移動平均値,ボリンジャー帯とRSIを組み合わせて,価格動向と取引シグナルに対する過剰購入/過剰販売レベルを評価します. 精度を向上させるために複数の指標の強みを活用します.
戦略論理:
移動平均値とボリンジャー帯を計算して価格傾向を決定します.
RSIを計算して,買い過ぎ/売過ぎのレベルを特定します.
価格がBB下帯とRSI上昇クロスオーバーを超えるとロングに入ります.
ストップロスを使って,取引ごとに損失を制御する.
利点:
複数の指標による検証は 不良取引を減らす
RSIはMAsの限界を補完します.
BBは脱出レベルを特定する
リスク:
複数のパラメータを最適化するのに時間がかかる
RSIとBBの間の冗長性がある
脱出は失敗や逆転に易しい
要するに,この戦略は,MAs,BBsおよびRSIを組み合わせて,トレンドと逆転の取引機会の両方を特定します.複数の指標を使用することで結果が改善できますが,パラメータの最適化とリスク管理が必要です.
