If it is a futures stop loss operation, most futures trading software now supports setting the effective time of the stop loss order, which can be set to be valid only on the next trading day or the cloud condition order is permanently valid. In other words, futures stop loss can only manage the current trading day according to their own needs, and can also manage the forward until the transaction is completed after the trigger condition.

If it is a stock stop loss operation, manual stop loss is needed in most cases, because most stock trading software can not realize automatic stop loss operation, so the effectiveness of stop loss operation is not controversial. In another case, take profit can also be entrusted to sell at a high price. If there is no transaction, it will only be valid on the same day, and the take profit order will be invalid after 15 pm. Because the system will carry out settlement and liquidation after the stock closes in the afternoon, the consignment order will automatically become invalid after the system liquidation. In addition, some paid trading software also has a stop-loss function similar to futures, which can also be set to be effective on the same day or within a certain period of time, mainly depending on their time requirements for stop-loss and stop-loss.
