The Reactive Platform SDK for Python.

The package only support python3.7 and python3.8, not for lower versions.

Install the package in a python environment:

$ pip install reactive-platform

Uninstall the package:

$ pip uninstall reactive-platform

The REST API has endpoints for different type data, e.g. orders, analytics and references. At this moment, this package only supports querying reference data. To access the platform, a API token must be granted from platform UI.

Create a client first:

from reactive.platform.rest.client import Client

key = 'xxx'
url = "https://api.platform.reactivemarkets.com"
rc = Client(url=url, key=key)

Reference data includes asset, instrument, venue and markets. Get those data:

asset_ref = rc.fetch_asset_ref()
# json format assets reference data
assets = asset_ref.to_json()
print("asset reference:\n", assets)
# dict format assets
assets_dict = asset_ref.to_dict()
print("assets dict:\n", assets)

# instr reference
instr_ref = rc.fetch_instr_ref()
instrs = instr_ref.to_json()
print("instrument reference:\n", instrs)

# venue reference
venue_ref = rc.fetch_venue_ref()
venues = venue_ref.to_json()
print("venue reference:\n", venues)

# market reference
market_ref = rc.fetch_market_ref()
markets = market_ref.to_json()
print("market reference:\n", venues)

If client uses pandas, the reference data can be viewed in a Dataframe table in jupyter-notebook:

import pandas as pd

df = pd.read_json(market_ref.to_json())
df

The websocket feed provides real-time level 2 market data snapshots and public trades via

wss://api.platform.reactivemarkets.com/feed

To access the feed gateway via web socket, create an FeedClient which manages the web socket connection and provides methods to access the gateway.

from reactive.platform.feed.feedclient import FeedClient

TOKEN = 'xxx'
addr = "wss://api.platform.reactivemarkets.com/feed"
feed_client = FeedClient(addr=addr, key=TOKEN)

Use feed_client to subscribe market data or trades for markets, see a full example in example/marketdata.py. The client can specify book view parameters in the request. Currently, the feed gateway supports, book depths (1, 5, 10, 20), tick grouping (1, 50) and frequency (100ms).

The message protocol via feed gateway is Flatbuffers, which provides an efficient serialization/deserializaton mechanism in terms of both processing and space requirements. The reactive-platform generated python classes Flatbuffer schema are located under reactivemarkets.papi.
