is Order Structure's average field always available?

{ info:
   { amount: 0.1,
     avg_price: 0.01047286,
     create_date: 1507721878000,
     deal_amount: 0.1,
     order_id: 22351619,
     orders_id: 22351619,
     price: 0.01068231,
     status: 2,
     symbol: 'ltc_btc',
     type: 'buy' },
  id: 22351619,
  timestamp: 1507721878000,
  datetime: '2017-10-11T11:37:58.000Z',
  symbol: 'LTC/BTC',
  type: 'limit',
  side: 'buy',
  price: 0.01068231,
  average: 0.01047286,
  amount: 0.1,
  filled: 0.1,
  remaining: 0,
  status: 'closed',
  fee: undefined }

that’s order info from okex. ‘average’ field not mentioned in doc https://github.com/ccxt-dev/ccxt/wiki/Manual#order-structure for me, i don’t care about the ‘price’ field, which i guess is the price i create order for. instead i need to know the average transaction price.
