Task 2

Description

For an exchange, get all trading pairs, their latest prices and trading volume for 24 hours

Task

• Create a class inherited from the BaseExchange class.
• Write the implementation of the methods and fill in the required fields (marked as "todo")

Note

• Feel free to add another internal methods.
• It is important that the example from the main function runs without errors

The flow looks like this:

1. Request data from the exchange
2. We bring the ticker to the general format
3. We extract from the ticker properties the last price, the 24-hour trading volume of the base currency and the 24-hour trading volume of the quoted currency. (at least one of the volumes is required)
4. Return the structure in the format:

{
    "BTC/USDT": TickerInfo(last=57000, baseVolume=11328, quoteVolume=3456789),
    "ETH/BTC": TickerInfo(last=4026, baseVolume=4567, quoteVolume=0)
}
