この記事で説明する戦略の本質は動的バランス戦略である.つまり,バランス通貨の価値は常に評価通貨の価値に等しい.しかし,戦略論理は,先行順序として設計されたとき非常にシンプルである.この戦略を書く主な目的は,戦略設計のあらゆる側面を示すことである.
戦略論理の封筒化 実行時にいくつかのデータとタグ変数 (オブジェクトとしてカプセル化) で戦略論理をカプセル化します.
戦略処理の初期化コード 初期アカウント情報は,利益計算のための初期実行で記録されます.初期実行時に,パラメータに従ってデータを復元するかどうかを選択できます.
戦略相互作用処理コード シンプルなインタラクティブな停止と再開の処理が設計されています
戦略利益計算コード 利益の計算には通貨標準計算方法が用いられる.
戦略におけるキーデータの持続性メカニズム データを復元するメカニズムを設計する
戦略処理情報を表示するコード 状態バーのデータ表示
