It will appear on the cr. side of Trading A/c.

No Closing Stock does not appear in Trial Balance.

A/C.

its does not apear either in trading a/c but is written in 
debitside of assets in balancesheet

No Closing Stock does not appear in Trial Balance.
Further Closing Stock will appear in Credit Side of Trading 
A/C.

Closing stock can come either in the trial balance or
outside the trail balance it depends upon the calculation of
purchase or cost of goods sold.

In first case when closing stock is the part of trial
balance then it will not be a part of trading account then
it will shown on the asset side of balance sheet 

In second case when closing stock is not a part of trial
balance means it comes as adjustment with trial balance then
it comes on the credit side of trial balance and it is also
shown on the asset side of balance sheet

Closing Stock doesnt appear in Trial Balance.
but appears in Credit Side of Trading 
A/C.

closing stock come under credit side of trading a/c , but it's not comes in trail balance, information given only in adjustment. usually adjustments given below the trail balance.

As such no body will maintain a closing stock / stock 
account in ledger.  Trial balance shows the ending balances 
of the ledger only, hence there is no question of taking 
closing stock in TB.  It appears in adjustments and to be 
shown on the credit side of Trading acct and in Balance 
sheet under Assets.
