ガウスチャネル適応移動平均戦略 (Gaussian Channel Adaptive Moving Average Strategy) は,ガウスチャネルフィルタリング技術と適応パラメータ設定を利用した定量的な取引戦略である.ジョン・エーラーズが提案したガウスチャネルフィルタ理論に基づいて,この戦略は,複数の指数的な移動平均計算を価格データに適用することによって,スムーズかつ適応的な取引信号を生成する.戦略の核は,ガウスチャネルフィルタリング価格からフィルタリングされた真の範囲を足し,減算することによって得られる上下帯で動的に調整された価格チャネルを構築することである.価格が上帯を超えるとロングポジションが入力され,下帯を超えるとショートポジションが入力される.さらに,戦略は,実行開始および終了時間のための柔軟な設定を可能にする時間段パラメーターを導入し,戦略の実用性を向上させる.
ガウスチャネル適応移動平均戦略の原則は以下のとおりである.
ガウスのチャネル適応型移動平均戦略には以下の利点があります.
多くの利点にもかかわらず,ガウスチャネル適応型移動平均戦略には依然としていくつかのリスクがあります.
ガウスチャネル適応移動平均戦略の最適化方向は以下の通りである.
ガウスチャンネルの適応型移動平均戦略は,ガウスフィルタリングと適応性パラメータに基づいた定量的な取引戦略で,動的に価格チャネルを構築することによってスムーズかつ信頼性の高い取引信号を生成する.この戦略は,強い適応性,良いトレンドフォロー能力,高いスムーズ性,大きな柔軟性,そして強力な実用性などの利点があります.しかし,パラメータ設定,突然の出来事,オーバーフィット,そして仲介などのリスクにも直面しています.将来,戦略は動的パラメータ最適化,マルチファクター融合,ポジション管理最適化,マルチインスタント調整を通じてさらに精製され強化することができます.

The maximum number of poles available in this script is 9. // Next, the data being analyzed is given a truncation option for reduced lag, which can be enabled with "Reduced Lag Mode". // Then the alpha and source values are used to calculate the filter and filtered true range of the dataset. // Filtered true range with a specified multiplier is then added to and subtracted from the filter, generating a channel. // Lastly, a one pole filter with a N pole alpha is averaged with the filter to generate a faster filter, which can be enabled with "Fast Response Mode". //Custom bar colors are included. //Note: Both the sampling period and number of poles directly affect how much lag the indicator has, and how smooth the output is. // Larger inputs will result in smoother outputs with increased lag, and smaller inputs will have noisier outputs with reduced lag. // For the best results, I recommend not setting the sampling period any lower than the number of poles + 1.
