Don't worry if your express buy quote has expired. This is usually not your fault. The system is actually protecting you — quotes are time-sensitive by design, and expiration is a normal mechanism. You just need to request a new quote.

Core Reason: Quotes Are Time-Locked
The quote provided by express buy (also called "flash swap") is a locked price designed to temporarily protect you from market fluctuations before you confirm the trade. This price is only valid for a short period. According to official OKX information, the "order preview" page usually has a 10–30 second countdown to lock the current quote.
If you do not confirm the order before the countdown ends, the quote will expire. At that point, the page will show a message like "quote expired" or something similar.
Step 1: Check Your Current Order Status
[What to do]: Determine whether the quote expired or the order was cancelled for another reason.
[How to do it]:
Case A: The page says "quote expired" or "quote invalid"
This usually happens because the 10–30 second quote lock time has ended, or the merchant's advertisement changed. It has nothing to do with your actions. Simply refresh the page.
Case B: The order shows "cancelled"
Check whether you accidentally tapped the cancel button. If it was cancelled and you have not paid, just place a new order. Repeated cancellations in a single day may trigger risk control restrictions, so avoid cancelling repeatedly.
Case C: The order shows "in progress" but the price is not moving
This may be caused by network delay. Try switching between mobile data and Wi-Fi to see which one is smoother, or restart the app.
[Done when]: You can confirm whether the current order status is "expired", "cancelled", or "in progress".
Step 2: Get a New Quote — Core Action
[What to do]: Refresh the page to get a new real-time quote.
[How to do it]:
Refresh directly: On the "order preview" page, if the countdown has ended, a "refresh" button usually appears. Tap it and the system will match a new quote.
Place a new order: If the order has expired or been cancelled, go back to the express buy page and enter the amount and payment method again as normal to generate a new order.
Switch network or update the app: If refreshing several times does not work, check your network connection or go to the app store to see if there is an app update.
[Done when]: You successfully enter a new "order preview" page and see a new quote and countdown.

Step 3: Confirm Quickly and Complete the Order
After getting a new quote, act a little faster. Quotes for C2C trading are usually valid for a very short time, so it is recommended to confirm and place the order before the countdown ends to avoid another expiration. Before confirming, quickly check that the payment amount and recipient information are correct.
Risk reminder: Express buy quotes include a spread, and the priority is convenience and speed. If you are price-sensitive or buying a large amount, you can go to the C2C self-select area to compare quotes from different merchants. You may often find a better price there.
