USDC-M Perpetual & Crypto-M Perpetual (OKX)  
 

30-day trading volume (USD)
Transactions are recorded in BTC equivalents according to price when trading. Every 24 hours, we convert your total trading volume to USD at 4 PM UTC according to the average price (= [closing price + opening price]/2). For example, you have traded OMG, XUC, BTC, LTC and BCH in the last 30 days. We recorded each transaction in BTC equivalents at the moment each trade happened. At each 4 PM UTC, we calculate your total trading volume in the last 30 days and convert it to USD according to the daily average price.

Snapshot assets include your OKX trading account assets in Matrixport.

Total asset balance
We take a snapshot of users’ all crypto assets at 4 PM UTC daily and convert the value to USDT, then to BTC based on the daily average price of BTC/USDT (BTC/USDT middle price = [opening price + closing price]/2).
Snapshot assets include your OKX sub-account total assets in Matrixport.

Makers and takers
Maker order is the limit order which enters into the order book before it can be traded in the market. For example, if the current BTC lowest ask price is 1,000 USDT and you create a maker order with a bid price 999 USDT, this order cannot be filled immediately. Then it will enter into the order book until someone fills it. After filling, you're required to pay the maker fee and the taker will pay the taker fee (or vice versa). You need to pay the taker fee when your limit ask order is traded successfully.
