Cette stratégie est une stratégie d’investissement intelligente qui combine la loi du coût moyen en dollars (DCA) et les indicateurs techniques de la ceinture de Brin. Elle consiste à investir en utilisant le principe de la régression des valeurs moyennes en construisant systématiquement des positions pendant les retournements de prix.
La stratégie est basée sur trois principes: 1) la méthode du coût moyen en dollars, qui réduit le risque d’optionalisation en investissant régulièrement des montants fixes; 2) la théorie du retour à la moyenne, qui considère que le prix reviendra à sa moyenne historique; 3) l’indicateur de la ceinture de Brin, qui est utilisé pour identifier les zones de survente. Lorsque le prix franchit la ceinture de Brin, le signal d’achat est déclenché.
Il s’agit d’une stratégie robuste qui combine l’analyse technique et une approche d’investissement systématisée. La stratégie est basée sur la reconnaissance des opportunités d’excédent et de baisse, en utilisant les méthodes de Brin, et sur la méthode du coût moyen en dollars pour réduire les risques. La clé du succès de la stratégie réside dans un réglage rationnel des paramètres et une discipline stricte d’exécution.

// Postscript:
// 1. Once you have set the "Investment Amount (USD)" in the input box, proceed with additional configuration.
// Go to "Properties" and adjust the "Initial Capital" value by calculating it as "Total Closed Trades" multiplied by "Investment Amount (USD)"
// to ensure the backtest results are aligned correctly with the actual investment values.
//
// Example:
// Investment Amount (USD) = 100 USD
// Total Closed Trades = 10
// Initial Capital = 10 x 100 = 1,000 USD
// Investment Amount (USD) = 200 USD
// Total Closed Trades = 24
// Initial Capital = 24 x 200 = 4,800 USD
