Uma vez que a estratégia no sistema de backtesting é geralmente concebida como um ciclo interminável, oonexit()A função implementada na estratégia de execução não pode ser activada no sistema de backtesting.onexit()A função pode ser activada pela detecção da marca final do sistema de backtesting (exceção EOF).
