This project is a partially implemented web API that returns historical stock market data (open, close, high and low prices) for stocks in the Indian Nifty50 stock index.

The project is implemented using python 3.6 and the starlette ASGI web framework.

• Clone or fork this repository
• Install requirements using pip install -r requirements.txt
• Run the server using python -m nifty
• Access the endpoint at localhost:8888/nifty/stocks/{symbol}

Implement the price_data function in __main__.py to return open, close, high and low prices for the requested symbol as json records.

For example:

GET /nifty/stocks/tatamotors/

should return

[
    {
        "date": "26/12/2003",
        "open": 435.8,
        "high": 440.5,
        "low": 431.65,
        "close": 438.6
    },
    {
        ...
    }
]

• The data is stored in the file data/nifty50_all.csv
• The endpoint should return one record for each row of data in the file
• Returned data should be sorted by date, most recent data first
• If an invalid symbol is requested, the endpoint should return 400 with an appropriate error message

Add a query parameter to the endpoint so that calling apps can request data for a single year.

For example:

GET /nifty/stocks/tatamotors/?year=2017

• This should only return rows for the specified year (and symbol)
• If there is no data for the specified year, an empty list should be returned
• If the year is invalid, the endpoint should return 400 and an appropriate error message

• You should use python 3.6 or above
• You may use any appropriate open source libs as part of your solution
• Please upload your project to github.com or similar and provide a link
• If you have questions please email [email protected]

Thanks for taking our test!
