For a pair that has been configured with a starting time and has not yet reached the starting time, the trading page of the pair in the foreground will be displayed as a starting countdown style, as shown in the figure below.
Since the starting time is not reached, you will not be able to place the order on this pair. Therefore, you can only place orders after reaching the starting time, which is not a good experience for users to trade on time, and we have made the following optimizations for this:

If the starting time of a pair has been configured and the opening time has not yet been reached and the pair is visible in the foreground, then you can set up a whitelist for this pair in the Background - Transaction - Spot - Basic Config - Crypto Pair - Pre-Market, please pay attention to the following points about the whitelist:
1. If the pair has not yet reached the starting time, the whitelist user you configured here has the permission to place an order before the starting time, and the API created by the whitelist user can also place an order normally.
2. Orders that are executed before the starting time will generate a K-line and cannot be repaired.
3. Orders placed by whitelisted users will be displayed in the order book of the pair immediately. Please place the order when the starting time is about to arrive.
4. After the whitelist is configured successfully, if you use the API created by the whitelist, you can place an order immediately; if a whitelist user logs in to the front desk to place an order manually, there will be a delay of up to 10 minutes due to caching.
