Nasdaq Cloud Data Service (NCDS)

Nasdaq Cloud Data Service (NCDS) provides a modern and efficient method of delivery for realtime exchange data and other financial information. Data is made available through a suite of APIs, allowing for effortless integration of data from disparate sources, and a dramatic reduction in time to market for customer-designed applications. The API is highly scalable, and robust enough to support the delivery of real-time exchange data.

Items To Note

Connecting to the API requires credentials, which are provided by the Nasdaq Data Operations team during an on-boarding process
This sample code only connects to one topic (NLSCTA); during on-boarding process, you will receive a topic list that you're entitled to.
See https://github.com/Nasdaq/NasdaqCloudDataService-SDK-Java for our officially support Java-based SDK.

Getting Started
Using the SDK

Getting Started

Python version support

The SDK currently supports Python 3.9 and above

Get the SDK

The source code is currently hosted on GitHub at: https://github.com/Nasdaq/NasdaqCloudDataService-SDK-Python

Clone the repository: git clone https://github.com/Nasdaq/NasdaqCloudDataService-SDK-Python.git
Move into the directory cd NasdaqCloudDataService-SDK-Python
Install the library and its dependencies from local source with pip install -e .

Optional: to use the Jupyter notebook provided,

Download Jupyter notebook using either pip pip3 install notebook or conda conda install -c conda-forge notebook
To run the notebook, use the command jupyter notebook and the Notebook Dashboard will open in your browser
Select the file python_sdk_examples.ipynb

Retrieving certificates

Run ncdssdk_client/src/main/python/ncdsclient/NCDSSession.py with arguments, which takes the path where the certificate should be installed.

For example: python3.9 ncdssdk_client/src/main/python/ncdsclient/NCDSSession.py -opt INSTALLCERTS -path /my/trusted/store/ncdsinstallcerts

Stream configuration

Replace example stream properties in the file kafka-config.json (https://github.com/Nasdaq/NasdaqCloudDataService-SDK-Python/blob/master/ncdssdk_client/src/main/python/resources/kafka-config.json) with provided values during on-boarding.

Required kafka configuration

"bootstrap.servers": {streams_endpoint_url}:9094
"ssl.ca.location": ca.crt

For optional consumer configurations see: https://github.com/edenhill/librdkafka/blob/master/CONFIGURATION.md

Client Authentication configuration

Replace example client authentication properties in the file client-authentication-config.json (https://github.com/Nasdaq/NasdaqCloudDataService-SDK-Python/blob/master/ncdssdk_client/src/main/python/resources/client-authentication-config.json) with valid credentials provided during on-boarding.

oauth.token.endpoint.uri: https://{auth_endpoint_url}/auth/realms/demo/protocol/openid-connect/token
oauth.client.id: client
oauth.client.secret: client-secret

A few examples:

Get first 100 records for given stream

python3.9 ncdssdk_client/src/main/python/ncdsclient/NCDSSession.py -opt TOP -n 100 -topic NLSCTA

Get all available streams

python3.9 ncdssdk_client/src/main/python/ncdsclient/NCDSSession.py -opt TOPICS

Using the SDK

Below are several examples for how to access data using the SDK. A Jupyter notebook with this same code and information is provided in the file python_sdk_examples.ipnyb

To run these examples, you will need the import and configuration dictionaries below. Replace the config information with your credentials.

from ncdssdk import NCDSClient

security_cfg = {
    "oauth.token.endpoint.uri": "https://{auth_endpoint_url}/auth/realms/demo/protocol/openid-connect/token",
    "oauth.client.id": "client",
    "oauth.client.secret": "client-secret"
}
kafka_cfg = {
    "bootstrap.servers": "{streams_endpoint_url}:9094",
    "ssl.ca.location": "ca.crt",
    "auto.offset.reset": "earliest"
}

Getting list of data stream available

List all available data stream for the user

ncds_client = NCDSClient(security_cfg, kafka_cfg)
topics = ncds_client.list_topics_for_client()
print("Data set topics:")
for topic_entry in topics:
print(topic_entry)

Example output:

List of streams available on Nasdaq Cloud Data Service:
GIDS
NLSUTP
NLSCTA

Getting schema for the stream

This method returns the schema for the stream in Apache Avro format (https://avro.apache.org/docs/current/spec.html)

ncds_client = NCDSClient(security_cfg, kafka_cfg)
topic = "NLSCTA"
schema = ncds_client.get_schema_for_topic(topic)
print(schema)

Example output:

[ {
"type" : "record",
"name" : "SeqAdjClosingPrice",
"namespace" : "com.nasdaq.equities.trades.applications.nls.messaging.binary21",
"fields" : [ {
  "name" : "SoupPartition",
  "type" : "int"
}, {
  "name" : "SoupSequence",
  "type" : "long"
}, {
  "name" : "trackingID",
  "type" : "long"
}, {
  "name" : "msgType",
  "type" : "string"
}, {
  "name" : "symbol",
  "type" : "string"
}, {
  "name" : "securityClass",
  "type" : "string"
}, {
  "name" : "adjClosingPrice",
  "type" : "int"
} ],
"version" : "1"
}, {...
} .......
.... ]

Get first 10 messages of the stream

ncds_client = NCDSClient(security_cfg, kafka_cfg)
topic = "NLSCTA"
records = ncds_client.top_messages(topic)
for i in range(0, 10):
    print("key: ", records[i].key())
    print("value: ", str(records[i].value()))

Example output:

topic = "NLSCTA"
print(ncds_client.get_sample_messages(topic, "SeqDirectoryMessage", all_messages=False))

Example output:

{'SoupPartition': 0, 'SoupSequence': 500, 'trackingID': 11578737109589, 'msgType': 'R', 'symbol': 'AMN', 'marketClass': 'N', 'fsi': '', 'roundLotSize': 100, 'roundLotOnly': 'N', 'issueClass': 'C', 'issueSubtype': 'Z', 'authenticity': 'P', 'shortThreshold': 'N', 'ipo': '', 'luldTier': '2', 'etf': 'N', 'etfFactor': 0, 'inverseETF': 'N', 'compositeId': 'BBG000BCT197', 'schema_name': 'SeqDirectoryMessage'}

Fix deserialization issue with a bytes field

Remove the serialization of the avro message into a json string. This is unneeded as the deserialize function is allowed to return any object, and it causes issues when there is an avro field of type bytes, as this is not a valid type for json objects.

Tracking Number Timestamp

In the Nasdaq Basic docs, I am seeing that "TrackingNumber/trackingID" for a quote is composed of the Nasdaq internal tracking number and the Timestamp in nanoseconds from midnight. I need to access the unix timestamp of this quote, and wanted to first see if there was a better way to access this than from manipulating the trackingID?

If not, I would like to confirm that the Timestamp in nanoseconds from midnight is assuming UTC?

Thanks.

Fix invalid notebook

I received the following error when trying to run the notebook:

Unreadable Notebook: NasdaqCloudDataService-SDK-Python/python_sdk_examples.ipynb NotJSONError('Notebook does not appear to be JSON: \'{\\n "cells": [\\n {\\n "cell_type": "m...')

After adding the missing comma, I was able to run the notebook with no issue
