概要

この戦略は,移動平均値,相対強度指数 (RSI),移動平均方向,その他の技術指標を合理的に適用することで,トレンドを正確に判断する.ダブル移動平均値の長短判断に基づいて,RSI指標は,誤ったブレイクを避けるために長短フィルタリングのために追加される.一方,異なるサイクルの移動平均値を共同に見ることで,トレンド方向を効果的に特定することができる.この戦略は大きな最適化空間を有し,さまざまな取引品種とサイクルに適用することができる.

戦略原則

この戦略は主に以下の技術指標に基づいて機能する.

  1. ダブル・ムービング・メアディア:高速・スロー・ムービング・メアディアの黄色の十字は,ロング・シグナルを意味し,デッド・クロスはショート・シグナルを意味する.この戦略では,EMAが移動平均を計算するために使用される.

  2. RSI指標:高いRSIレベルからの低下は短い機会を示唆し,低いレベルからの回復は長い機会を示唆する.この戦略ではRSI論理がトレンドフィルタリングに使用される.

  3. 移動平均の方向性: 長い移動平均と短い移動平均の方向性を比較することで,トレンドを決定することができます.この戦略では200期EMAが長期の方向性を決定するために使用されます.

取引の論理は次のとおりです

  1. 速いEMAがスローEMAを横切るときにロング,速いEMAがスローEMAを横切るときにショート.

  2. 高度のRSIレベルからの低下は短期間の機会を増加させ,低水準からの回復は長期間の機会を増加させる.

  3. 長期トレンド (200日EMA) に一致する方向での取引のみを行う.つまり,上向きトレンドではロング,下向きトレンドではショートする.

  4. 脱出ポジションに利益とストップロスを使う.

利点分析

この戦略の利点は以下の通りです.

  1. 複数の技術指標の組み合わせは,トレンドの方向性を確認し,誤ったブレイクの可能性を減らすのに役立ちます.

  2. RSIフィルターを追加すると 傾向が逆転すると ストップを避けられます

  3. 短期,中期,長期の動向を利用することで 進出のタイミングと方向性を改善できます

  4. ストップ・ロスの設定は,単一の取引の損失を制限するためのリスク制御を提供します.

  5. 調整可能なパラメータにより,異なる商品の多時間枠取引に適応できます.

リスク分析

この戦略にはいくつかのリスクもあります:

  1. ストップ損失は,強いトレンドにおける短期的な引き下げによって引き起こされる.より広いストップ損失範囲または移動/トレーリングストップ損失を使用することができる.

  2. RSIのフィルタリング範囲や ドンチアン・チャネルなどの追加指標が役立つかもしれません.

  3. パラメータの最適化が不適切である場合,過剰な取引につながる可能性がある.異なる製品に対して注意深くテストと最適化が必要である.

  4. この戦略は,技術的な要素のみに基づいています.主要な傾向を決定するには,基本的な分析が必要です.

オプティマイゼーションの方向性

この戦略は,次の側面で最適化できます.

  1. 移動平均期間を調整し,異なる市場サイクルに適応する.

  2. ロング/ショート選択の精度を向上させるために RSI パラメータを最適化する.

  3. ボリンジャー帯やケルターチャネルなどの追加指標をテストして 突破成功率を向上させる

  4. トレンドを把握するために ストップ・ロスの動きや遅れを試してください

  5. トレンドが弱くなると 誤った信号を減らすために 範囲の突破操作を研究する

  6. 合理的なストップ・ロスを設定し,リスク管理のために製品の特徴に基づいて利益値を取る.

  7. 取引サイズをコントロールして 単一の賭けを 過剰にしないようにします

概要

この戦略は明確な論理を持ち,実装が容易である.適切なパラメータチューニングによって,強烈なトレンドを伴う容量を持つさまざまな製品やサイクルに適用することができる.範囲限定市場に閉じ込まれるのを避けるためにリスク管理は重要です.市場状況と個人的な好みに基づいてカスタマイズされた最適化が行うことができます.
