What is the price reference for buying or selling US shares in Pluang?

The price listed on the US Stock asset display outside of trading hours is the last price traded on the exchange during regular hours. When the exchange is open, the price will continue to move following the price movement on the exchange, including during additional trading hours (pre-market and post-market trading). Meanwhile, the price on the Advanced Chart menu only records price movements during regular trading hours. So it can be used as a reference for buying or selling prices, but keep in mind that the actual buying and selling prices are the prices when the asset is actually purchased or sold.
