Aio-Trader

An Async library for accessing Indian stockbroker API and real-time market feeds.

Currently supports only Zerodha Kite (KiteConnect and Kite Web)

This Library is currently in Alpha. Expect breaking changes. Once testing is complete, I will release a pip package, and begin work on adding other brokers.

Supports python 3.8+

Installation

1. Clone the repo

git clone https://github.com/BennyThadikaran/Aio-Trader.git

cd aio_trader

2. Create a virtual env using venv and activate it.

py -m venv .

source bin/activate

# On Windows, run the below to activate venv
.\Scripts\Activate.ps1

3. Install aio_trader

pip install .

Note on Windows compatibility

The aio_dns package requires SelectorEventLoop to work correctly. Import the sys module and add the below code, before any async code is run.

if 'win' in sys.platform:
	asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

Uvloop / Winloop

Uvloop is a fast, drop-in replacement for the default event loop. It only works on Linux/Mac. On Windows, you will need Winloop.

Once installed, you can add the below code after your imports. Replace asyncio.run(main()) with run(main())

if 'win' in sys.platform:
    from winloop import run
else:
    from uvloop import run

This setup works well with aio_dns no need to set an event loop policy on Windows.

Differences between Aio-Trader and pykiteconnect (KiteConnect Official library)

aio-trader	pykiteconnect
Uses aiohttp	Uses Twisted, an event-driven framework
Supports Python version 3.8+	Supports Python version 2 & 3

Aio-Trader has fewer dependencies owing to its Python support.

KiteFeed uses the python struct module to parse binary data. It tries to unpack all values in a single function call, which is slightly more efficient.
