Closing Price of stock

hello there,

I'm researching about closing price in fyers, but i am bit confused.

Quotes API : in the documentation it clearly mentioned that prev_close_price is the price which is previous day's closing.
Market Depth API : in the documentation it says that c is Price at the of market closing.

In Market Depth API the closing Price is not getting changed when market get closed.

My concern is that i want the closing price of MCX and NSE stock's of the current day after the market get close.

Please, Guide me with this.
