Asset Growth Effect

取引規則

資産成長率 = 最新公表年度の TotalAssets / 一年前の同じ決算日の TotalAssets − 1。両報告は信号時点で公表済みである必要があります。最低 Quantiles を買い、最高を売り、片側 floor(適格数 / Quantiles) 銘柄。最低 Quantiles 組の報告が必要です。既定は毎年七月です。

毎年 RebalanceMonth の最初の適格な同期確定足で一度リバランスします。後日の公表は過去の判断に影響しません。MaxReportAgeDays は PeriodEnd から数えます。

入力データ

FundamentalsFile は必須 CSV です：SecurityId,PeriodEnd,PublishedAt,TotalAssets,NetIncome,OperatingCashFlow,BookEquity,SharesOutstanding。PeriodEnd は yyyy-MM-dd、PublishedAt は yyyy-MM-ddTHH:mm:ssZ（UTC）。資産と株数は正である必要があります。信号時点で公表済みの最新会計期間と最新改訂だけを選びます。重複改訂や期末より前の公表は禁止です。足から財務値を作りません。

パラメーター

パラメーター 既定値
Universe 必須
Capital 100000
Leverage 1
MinTradeUsd 50
CandleType TimeSpan.FromMinutes(5).TimeFrame()
Quantiles 10
FundamentalsFile 必須
RebalanceMonth 7
MaxReportAgeDays 550

約定と保有数量

Universe を明示的に設定します。価格と Capital は取引単位当たりの USD です。Capital は固定予算、Leverage は総エクスポージャーを指定します。損切りや利食い注文は追加しません。

買い・売りの各バスケットに Capital × Leverage の半分を均等配分します。信号終値で数量に換算し、VolumeStep 単位でゼロ方向へ丸めます。実際の約定残高を使い、未完了注文を待ち、MinVolume/MaxVolume を守って大口調整を後続足へ分割します。MinTradeUsd は小口調整を除外しますが、全決済には適用しません。

検証

約定検証には既存 BTC/TON アーカイブのみを使います。明示した財務報告、オプション観測、準備価格は仕組みのテスト用で、実企業財務やオプション履歴ではありません。短縮期間、二分位、三月の年次調整は明示的な検証設定で、元の長期既定値の取引を証明しません。収益率は主張しません。
