1. Open Snowball APP and select the "Transaction" option in the bottom navigation bar.

2. In the transaction page, select the "Order" option.

3. On the order page, you can view all the historical order records, including the stocks bought and sold, as well as the time, price and quantity of buying and selling.

If you can't find the order record in Snowball APP, it may be that there is no transaction, or you have used other trading platforms. In any case, you can check the trading order record by querying the trading account.
