Nubra Python SDK V3

OMS V3

Nubra's most powerful OMS is here with Nubra Python SDK 0.5.2. This documentation covers authentication, market data, instruments, trading, and portfolio workflows for the current V3 payload structure.

Use NubraEnv.PROD for live production usage and NubraEnv.UAT for sandbox testing.

The Nubra Python SDK V3 gives Python developers a higher-level interface for authentication, market data, instruments, orders, and portfolio workflows without having to build low-level HTTP and session plumbing from scratch.

Use this page as the main entry point for installation, first-run setup, and the most common SDK workflows.

What's New In V3

This documentation set is intended for users building with the current OMS V3 trading payload structure using SDK 0.5.2.

This documentation set focuses on:

  • the current V3 order and payload structure
  • the Python SDK 0.5.2 release line
  • a cleaner and more unified order workflow
  • trading examples aligned to the OMS V3 flow
  • portfolio, market-data, and realtime workflows for production and sandbox integrations

Key Sections

If you are getting started, start with these pages first:

  1. Authentication
  2. Trading Overview
  3. Place Order
  4. Place Multiple Orders
  5. Place Strategy Order
  6. Get Order Margin
  7. Realtime Order Updates

Quick Start

For a new SDK 0.5.2 integration, use this order:

  1. Review Release Notes to understand the 0.5.2 release line.
  2. Complete Authentication using SDK 0.5.2.
  3. Resolve instruments through Get Instruments before quotes or order workflows.
  4. Read Trading Overview to understand the V3 order model and updated request shape.
  5. Run one end-to-end order path using Place Order or Place Strategy Order, depending on your workflow.

Start here

If you are new to Nubra APIs, follow this order:

  1. Install SDK 0.5.2
  2. Complete Authentication
  3. Use Get Instruments
  4. Fetch Current Price or Market Quotes
  5. Move to Place Order when your integration is ready

Why Use The Python SDK

Use the Python SDK when you want:

  • a faster Python integration path
  • built-in client abstractions for trading and market data
  • a cleaner development workflow than raw HTTP requests
  • support for production and sandbox V3 workflows

If you prefer direct HTTP control or a language-agnostic integration path, use the REST API documentation instead.

Before You Install

Before installing the SDK, make sure you have:

  • Python installed
  • a Nubra account with API access
  • your registered phone number and MPIN

Recommended:

  • Visual Studio Code with the Python extension

Install Python from python.org.

Verify your Python installation:

python --version

python3 --version

Installation

Install the V3 SDK from PyPI:

python -m pip install nubra-sdk

If python points to Python 2 on your system, use:

python3 -m pip install nubra-sdk

Upgrade an existing installation:

python -m pip install --upgrade nubra-sdk

Environment choice

Use NubraEnv.PROD for live production usage and NubraEnv.UAT for sandbox testing.

SDK Quick Start

The usual SDK workflow is:

  1. Install nubra-sdk 0.5.2.
  2. Initialize the SDK client with the correct environment.
  3. Authenticate with OTP or TOTP and MPIN.
  4. Resolve instruments and ref_id values.
  5. Fetch market data or place trades.

Example:

from nubra_python_sdk.start_sdk import InitNubraSdk, NubraEnv
from nubra_python_sdk.refdata.instruments import InstrumentData
from nubra_python_sdk.marketdata.market_data import MarketData
from nubra_python_sdk.trading.trading_data import NubraTrader

# Use NubraEnv.PROD for live usage. Use NubraEnv.UAT for sandbox testing.
nubra = InitNubraSdk(NubraEnv.PROD, env_creds=True)

instruments = InstrumentData(nubra)
market_data = MarketData(nubra)
trader = NubraTrader(nubra)

Common Next Steps

After installation, most users continue with these pages:

  1. Authentication
  2. Get Instruments
  3. Current Price
  4. Market Quotes
  5. Place Order
  6. Positions

SDK Areas

The SDK provides Python access to these main areas:

Market Data

  • Current price snapshots
  • Market quotes
  • Option chain snapshots
  • Historical OHLC data
Start with Current Price

Real-Time Data

  • Real-time quotes
  • Option Greeks stream
  • OHLCV stream
  • Order book stream
  • Index stream
Start with Realtime Data

Trading

  • Place orders
  • Modify and Cancel orders
  • F&O Strategies orders
  • Margin checks
  • Real-time order updates
Start with Trading Overview

Important Notes

Implementation details

  • The install package name is nubra-sdk, but the Python import root is nubra_python_sdk.
  • Trading methods use the OMS V3 trading flow.
  • ref_id is a key identifier across quote, market-data, and trading workflows.
  • Use NubraTrader(nubra) for Trading API V3 order workflows.
  • Resolve instruments before placing orders.

Review Release Notes before changing SDK versions.

Before building polling-heavy or streaming-heavy systems, review API Rate Limits.

SDK Or REST API

Choose the Python SDK if you want:

  • a faster onboarding path in Python
  • built-in SDK abstractions
  • a more convenient trading and market-data workflow in Python

Choose the REST APIs if you want:

  • direct HTTP control
  • language-agnostic integration
  • lower-level implementation flexibility
