Chiusura di N ordini a mercato

Dopo aver aperto posizioni multiple, questo snippet chiude N ordini (“Nb Order”), a partire da un MagicNumber

Ad esempio, hai 5 posizioni con Magic Number: 1004, 1003, 1002, 1001, 1000.

Inserisci il Magic number: 1004

Inserisci Nb Order: 5

Chiuderà le 5 posizioni.

Ecco il codice
