Release Notes¶

This document contains the release history and changes for the Nubra Python SDK.

Version 0.3.8¶

Index WebSocket – Open Interest (OI) Support
The Index WebSocket now exposes Open Interest (OI) data for applicable instruments.
Real-time OI updates for Futures and Options are now available via the index WebSocket stream
The volume_oi field is included in the Index WebSocket payload when applicable
For non-derivative instruments (e.g., spot indices, equities), volume_oi will be None

Positions API (V2 Support)
The Positions API now supports V2, with additional fields to provide clearer position-level visibility:
Buy Quantity – Total quantity bought for the position
Sell Quantity – Total quantity sold for the position

Flexi Basket Modification – Modify existing Flexi basket orders, including entry price, exit price, stoploss, timing, and multiplier (subject to order type rules)
Get Margin API – Estimate margins for single-leg and multi-leg strategies with portfolio hedge benefits and final authoritative margin calculation
Greeks WebSocket – Real-time streaming of option Greeks (Delta, Gamma, Theta, Vega, IV) for live risk monitoring and strategy management
OHLCV WebSocket – Real-time OHLCV candle data via WebSocket for intraday analytics, indicators, and automated trading systems

Version 0.3.5 — internal change in the WebSocket endpoint for market-data.

We provide two endpoints for the WebSocket market-data:

In version 0.3.5, the new WebSocket endpoint is used by default. To use the older WebSocket endpoint on version 0.3.5, pass socket_v2 = false.

For versions prior to 0.3.5 (i.e., ≤ 0.3.4), no flag is required — the previous endpoint will behave as before.
