How to Change the Quote Currency After Opening an OKX Account?
Modifying the quote currency actually falls into two scenarios: one is the "display fiat currency" (e.g., showing total asset value in CNY or USD), and the other is the "trading quote unit" (e.g., whether a contract is quoted in BTC or USDT). The methods differ, so we'll first clarify the classification and then provide detailed step-by-step instructions.

1. Prerequisite: Distinguish Which Type You Want to Change First
Before you start, make sure you understand which type of setting you need to adjust.
Scenario A: You only want to display the total asset value in a fiat currency such as CNY, USD, etc. — This belongs to "display preferences." It does not affect trading; it just makes viewing your assets more convenient.
Scenario B: You want to change the trading quote unit from USDT to BTC, ETH, or another asset — This is the "trading quote currency," which directly affects the K-line chart, order book prices, and profit and loss calculations you see.
Clarify your need first, then proceed.
2. Changing the Fiat Currency Display (USD, CNY, EUR, etc.)
If you only want to show your account's total asset value in a specific fiat currency, the path is very intuitive.
App: Tap the menu icon in the upper left corner → Select "Account settings" → Preferences → Currency, then choose the fiat currency you want to display, such as USD, CNY, EUR, etc.
Web: Click the profile icon in the upper right corner of the page → Select "Preferences" → Currency, then choose the target fiat currency.
Success indicator: Return to the assets overview page. You will see the total asset value switched to your chosen fiat, e.g., from "$10,000" to "¥72,000".
Common failure reason: Many people confuse "fiat display" with "trading quote." Fiat display is only a viewing preference and does not affect any order price or profit and loss calculation.
3. Changing the Trading Quote Unit (USDT, BTC, ETH, etc.)
This operation affects the quotation method you see in the trading interface. For example, if you change the quote unit from USDT to BTC, the BTC/USDT trading pair will become BTC/BTC (i.e., pricing BTC against BTC, essentially using BTC as the base to display the price).
App: Go to the "My" page → Tap the gear icon in the upper right corner to enter "Settings" → Select "Trade settings" → Find the "Preferred quote currency" module → Tap the currently displayed quote unit (e.g., "USDT") and choose the target currency from the list. Supported options include USDT, BTC, ETH, BNB, OKB, USD, etc.
Web: Hover over the profile icon in the upper right corner → Click "Account settings" in the drop-down menu → In the left navigation bar, select "Trade preferences" → In the "Default quote unit" area, set the quote unit for products like spot, margin, and derivatives. You can set different quote units for different products, e.g., spot in USDT and futures in USD. If you check "Sync to App" on the web, the modification will automatically sync to your mobile device.
Success indicator: Return to the market page. The price unit of trading pairs will have changed to your new quote currency. For example, if it originally showed "BTC/USDT = 60,000", after changing to BTC quote it might show "BTC/BTC = 1" (using BTC as the base), or after changing to ETH quote it shows "BTC/ETH = corresponding value".
4. Special Settings for Contract Settlement Currency
If you are trading USD-margined contracts, there is a separate "settlement currency" setting.
USD-margined contracts support setting the settlement currency to USD, USDC, or USDG. Go to Sub-account → Trade settings menu → Select "USD-margined settlement currency" to configure it.
Note: If you currently have open orders or positions in USD-margined contracts, changing the settlement currency is not allowed. If not set, the platform defaults to USD settlement.
Success indicator: The margin, PnL, and fee data displayed on the contract page will all switch to the new settlement currency.
5. Independent Sub-Account Settings (Advanced Scenario)
Sub-accounts follow the main account's quote settings by default, but they can be overridden independently.
Go to "My" → "Sub-account management" → Select the target sub-account → Tap "More" → "Trade settings" → In "Quote unit," uncheck "Follow main account" and customize a dedicated quote currency for the sub-account (four options: USDT, BTC, ETH, USD).
FAQ
Q: Does changing the quote currency affect my position PnL? No. The quote currency is only a display method and does not change the actual transaction price or profit and loss amount. For example, if you go long on the BTC/USDT pair, your PnL is always calculated in USDT; only the displayed number is converted into another currency for viewing.
Q: Why can't I change the settlement currency of my USD-margined contract? Because there are open positions or pending orders. You must close all positions and cancel all orders before you can modify the settlement currency.
Q: Does displaying fiat currency (CNY) require identity verification? In some scenarios, yes. OKX's fiat display feature (e.g., showing CNY) usually requires the account to complete identity verification to comply with relevant regulations.

Operation Tips
Confirm whether you need to modify the fiat currency display or the trading quote, and follow the corresponding steps. After the change, go to the market or asset page to check if the display has been updated. If you are modifying the contract settlement currency, ensure there are no open positions or pending orders; otherwise, the modification cannot be completed.
