Trade copier with mql signal

hi , i follow a mql signal but i need a type of copier or script which can split the lot size to small parts ..say if the sender account is opening .20 lot it should be opened in my account in multiple small parts , as i have set the lot size of .05 so in my account it should open 4 lots of .05 ..each lot will be opened after a given delay in seconds ..also when the sender account closes lot all the split lots will be closed from account and it will also use the same sl and tp from sender account .
