ダブルEMAクロスオーバー戦略は,一般的に使用されるトレンドフォロー戦略である.異なる期間の2つのEMAラインを使用し,短い期間のEMAが長い期間のEMAを横切ると購入信号を生み出し,逆の期間のEMAが起こると販売信号を生成し,トレンドの変化を把握する.
この戦略のコアロジックは,EMAラインの"黄金十字"と"死十字"の原則に基づいている.EMAは価格データを効果的にスムーズにし,トレンド方向を示すことができる.短い期間のEMAは価格変化により迅速に対応し,長い期間のEMAはノイズに敏感性が低く,長期的なトレンドを反映する.短い期間のEMAが長い期間のEMAを横切ると,上向きの勢力が強くなっているという信号と見なされる.逆のことが起こると,下向きの勢力が加速していることを示す.この戦略は,この論理に基づいた取引信号を生成する.
具体的には,この戦略は,長さ1と長さ2パラメータを使用して,2つのEMAラインの期間を設定します. demaVal1は長さ1期EMAであり, demaVal2は長さ2期EMAです.これらは以下のように計算されます.
demaVal1 = EMA(close, length1)
demaVal2 = EMA(close, length2)
EMAが計算する関数である. demaVal1が demaVal2を横切ると,買い信号 demaCrossoverが生成される.逆が起こると,売り信号 demaCrossunderが生成される.この戦略は,これらの2つの信号に基づいて取引注文を送信する.
この戦略の利点は以下の通りです.
この戦略にはいくつかのリスクもあります.
上記のリスクに基づいて,次の側面を最適化することができる:
結論として,ダブルEMAクロスオーバー戦略は,シンプルで実用的なトレンドフォローリングシステムである.EMA分析の成熟した理論を継承し,適切なパラメータ調整とフィルター条件の改善により,適切なアプリケーション見通しを持つ異なる楽器のトレンド取引に適用することができる.
