Fechamento de N Ordens a Mercado

Após abrir múltiplas posições, este snippet fecha N ordens ("Nb Order"), a partir de um MagicNumber

Por exemplo, você tem 5 posições com o Magic Number: 1004, 1003, 1002, 1001, 1000.

Você insere o Magic Number: 1004

Você insere Nb Order: 5

Ele fechará as 5 posições.

Aqui está o código
