Futures Trading

On t+1 day I have payout for a particular trade date and also payin for different trade date? Will payout and payin run seperately ?

No, if different payin and payout are falling on the same day, amount would be first internally adjusted against each other and only net amount would either be recoved or paid. In cash projection, distinct particulars would be given for payin/payout internally settled and settled by way of debit/credit in bank. Setting Trading Limits.
