Calcule l'excursion défavorable maximale (MAE) combinée la plus défavorable lorsque plusieurs positions sont ouvertes simultanément, vous aidant à quantifier les drawdowns dans les stratégies d'entrées échelonnées (basket).
Biggest MAE - utile pour analyser les stratégies avec des ordres uniques ou multiples.
Ordres multiples vs Ordre unique
Il est plus efficace de répartir le risque sur un panier d'ordres plutôt que sur un ordre unique. Les entrées multiples offrent plus de flexibilité sans exiger une précision absolue sur une entrée unique.
Lors de l'ouverture simultanée de plusieurs ordres dans la même direction, calculez le MAE total de toutes les positions ouvertes. Si les positions sont dans des directions opposées (hedging), soustrayez le MFE des positions opposées du MAE le plus important pour obtenir le MAE global.
Quatre snippets
BiggestMAEallTrade - Plus grand MAE pour un contrat, normalisé par contrat pour des résultats précis même si la stratégie augmente la taille de contrat pendant le backtesting.
