ESG Factor Momentum

取引規則

Universe には ESG 審査済みの銘柄を指定します。ESG 評価を価格から生成しません。LookbackDays + 1 個の確定日足終値で momentum = P[d] / P[d−LookbackDays] − 1 を計算します。全銘柄が負の収益率でも毎月の最上位だけを買います。銘柄が変わらなくても毎月旧ポジションを全決済し、約定を待ってから買い直します。予算は報告されたポートフォリオ価値を上限とし、レバレッジや空売りを行いません。

時刻が一致する確定足だけを評価します。統計は異なる UTC 日付を数え、同じ日の後続足が日次価格を更新します。毎月最初の条件を満たす同期確定足で一度リバランスします。データ不足時は延期し、同点は Security.Id 順に並べます。

全観測値はシグナル足の終値時刻までに公表されている必要があります。日中足では当日 UTC 日付より前の日足価格だけを使い、確定日足では自身の日付を使えます。将来の CSV 日付で判断を先取りしません。

入力データ

PriceHistoryFile は正の日次終値の任意 CSV です：SecurityId,Date,Close。日付は yyyy-MM-dd。現在・将来の日付で判断を先取りせず、実際の確定足で該当 UTC 日の価格を上書きします。重複日付は禁止です。短い約定履歴で長い期間を準備するために使えます。

パラメーター

パラメーター 初期値
Universe 必須
Capital 100000
MinTradeUsd 100
CandleType TimeSpan.FromDays(1).TimeFrame()
PriceHistoryFile 任意 — 未指定
LookbackDays 252

約定と保有数量

Universe を明示し、価格と Capital は取引単位当たり米ドルです。買い保有額の上限は min(Capital, 報告された Portfolio.CurrentValue) で、価値が不明または非正なら購入予算はゼロです。レバレッジ、ストップロス、利食い注文はありません。

目標数量は VolumeStep に従いゼロ方向へ丸めます。新規建ての前に全決済の実約定を待ち、実保有数量と照合します。MinVolume/MaxVolume を守り、大きな調整を後続足へ分割します。MinTradeUsd は非ゼロ目標への調整を制限し、全決済には適用しません。

検証

両言語を同梱 BTC/TON 約定データと明示的な金利・財務・評価・文章・事前履歴データで検証します。カレンダー検証はアーカイブの OHLC・出来高の日付を移し、決まった約定気配を与えたもので、複数年の市場履歴ではありません。独立計算、注文方向・数量、実約定、残高、禁止判断日を確認します。2区分、K=1、AssetDecile=1 は明示的な機構検証設定であり、全本番銘柄群の証明ではありません。収益を保証しません。
