After the market closes at 4: 30 p.m., the stock exchange begins liquidation, which can be entrusted after the liquidation. According to the daily trading volume, the closing time varies, and it is basically stable after 10 in the afternoon. It is suggested that overnight entrustment can be operated after 10 in the afternoon, so as to avoid premature liquidation as the same-day entrustment.
Next-day entrustment is an incremental service provided by brokers to accept orders entrusted by customers before the trading day. Every other day's entrustment service provided by various brokers is different in details, and some even do not provide the next day's entrustment service. Therefore, the specific entrustment rules need to consult their respective brokers.
