Design a class that records daily stock trading activity and returns all recorded trades in sorted order.

Requirements:

Implement a method to register a trade.
Each trade contains at least:
- a timestamp
- a stock symbol
- whether the action is buy or sell
- a quantity or amount
Implement a method getAllTrades() that returns every recorded trade sorted by:
1. timestamp ascending
2. amount ascending when timestamps are equal

You should describe the class interface, the data structures you would use, and the time complexity of the main operations.
