概要

この戦略は,相対強度指数 (RSI) と重度の移動平均 (WMA) という2つのよく知られた指標に基づいています.市場傾向を特定し,その方向性を追います.RSIは過買い/過売値を判断し,WMAは価格傾向を決定します.両者の組み合わせは,無関係な信号を効果的にフィルターし,収益性を向上させることができます.これは,利益/損失に基づいてポジションサイズを調整するマネーマネジメント方法と組み合わせた中長期戦略です.

戦略の論理

RSI インディケーター

RSI は,最もよく知られる過買い/過売り指標の1つである.その式は:

$$RSI=100 - \frac{100}{1+\frac{AvgGain}{AvgLoss}}$$

AvgGain は過去 x 日間の 閉店がオープンより高い日の平均であり,AvgLoss は過去 x 日間の 閉店がオープンより低い日の絶対値の平均である.

この戦略では,傾向を判断するためにRSI期間を20に設定します.60を超えるRSIはロング信号を生成し,40以下のRSIはショート信号を生成します.

振込金について

SMAと比較して,WMAは最近の価格をより重く評価する.その公式は:

$$WMA = \frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}$$

この戦略では,次の重量式を使用します.

$$w = \begin{cases} 100/(4+(n-4)1.3), i <= 3 \ 1.3 となっている.w, & i > 3 \end{case}$$

体重は過去3日間で同じで,1日ごとに1.3倍も下がっています. これは最近の価格の影響を示しています.

この戦略におけるWMAの長さは20です

戦略信号

長期信号:RSI > 60 と WMA の20 日 ROC < -1 短信号: RSI < 40 と WMA の 20 日 ROC > 1

WMAの20日ROCは以下のように計算される.

$$ROC = (WMA_{today}/WMA_{20_days_ago} - 1) \×100$$

利点

  • RSI を使ってトレンドの方向性を決定し,ウィップソー市場でお金を失うのを避ける
  • WMAは,騒音を減らすため,最近の価格を推量し,主要な傾向を特定する
  • RSI と WMA ROC の組み合わせにより,無関係な信号がフィルタリングされます.
  • 複数のATR後継得益,柔軟な得益
  • 資金管理は,利益/損失に基づいてポジションサイズを調整し,リスクを制御する

リスク

  • パラメータの設定が正しくない場合,取引頻度は増加する可能性があります.
  • 誤ったストップ損失設定は損失を増やす可能性があります.
  • トレンドフォローストラテジーのように,範囲限定市場には適さない
  • マクロ環境の変化に注意し,必要に応じて手動介入

改善 の 方向

  • テスト RSI 長さ,WMA 長さ,ROC 値 最適パラメータセットを見つけるために
  • 最適なポジション調整計画を発見するために,さまざまなマネーマネジメント方法をテスト
  • さらに信号フィルタリングのための他の指標を追加
  • ストップ・ロスの戦略を組み込む
  • トレンド中に利益を最大化するために利益戦略を最適化

結論

この戦略は,RSIとWMAを組み合わせて,中長期間の主要なトレンドから利益を得ることを目的として,トレンド方向を決定する.マネーマネジメントと利益採取戦略もリスク制御に使用される.これは実用的な価値がありますが,パラメータ設定とストップロスのメカニズムはより良い結果のために継続的なテストと最適化が必要です.投資家は状況を評価し,必要に応じて手動で介入し,制御可能なリスクを確保する必要があります.
