We are thrilled to announce the launch of Alpaca-py ? our official Python SDK that offers app developers and traders a versatile and developer-friendly user interface that enables you to easily interact with Alpaca's complete suite of APIs for building your own trading app to trading to streaming real-time crypto and stock market data.
Alpaca Python SDK Built to Enhance Developer Experience
A Developer-Friendly Python SDK for all of Alpaca APIs
Due to its simplicity and versatility, Python is one of today’s most popular programming languages, with an estimated 8.2 million users 1.
Alpaca-py is a Python library built by Alpaca that offers complete module structures with relevant tools, documentation, code samples, examples, and guides to provide you with a cohesive interface to interact with Alpaca’s complete set of API products.
What’s New?
In addition to the Market Data and Trading APIs, Alpaca-py also lets you use Broker API and Alpaca Connect through Python. Broker and Connect partners can also use Alpaca-py to provide investment services to their users. Alpaca-py also makes it easy to use python to create your own investment app on Alpaca.
Compared to the previous SDK alpaca-trade-api, Alpaca-py has an upgraded idiomatic Python codebase and generated documentation from docstrings. The SDK includes well-documented models that simplify the process of submitting large object payloads.
Here is an example of submitting a market order in Alpaca-py.
from alpaca.trading.client import TradingClient
from alpaca.trading.requests import MarketOrderRequest
from alpaca.trading.enums import OrderSide, TimeInForce
client = TradingClient('api-key', 'secret-key')
request_params = MarketOrderRequest(
symbol="SPY",
qty=3,
side=OrderSide.BUY,
time_in_force=TimeInForce.DAY
)
client.submit_order(order_data=request_params)
Note: Alpaca Connect Marketplace documentation will be coming soon.
What will happen to the previous Python SDK?
Moving forward, we will continue to support the alpaca-trade-api SDK until the end of 2022. This means we will patch bugs but will stop pushing new features. At the end of this year, we will deprecate the repository and will no longer push any new changes or patches.
