During the grey market trading session, the market value and profit/loss of your position are calculated based on the latest grey market price and are provided for reference only.
After 12:00 AM (24:00) on the grey market trading day, the system will revert to calculating the market value and profit/loss based on the latest exchange price (i.e. the IPO offer price). As a result, your displayed market value and profit/loss may change.
This will not affect your actual assets or realised returns.
