# Version 2.0.0.3 Released #### Version 2.0.0.3 Released **Date: 13th Apr 2026** **Feature Release: Async-to-Sync WebSocket Migration, Market Price Protection (MPP), Samco 2FA, Shoonya OAuth, Multi-Device Session Tracking & Security Hardening** This is a feature release featuring **59 commits** (excluding auto-builds) from **7 contributors**, focused on migrating broker WebSocket adapters from asyncio to sync for Docker/eventlet compatibility, Market Price Protection (MPP) for Zerodha/Kotak/Samco/Tradejini, Samco 2FA authentication, Shoonya OAuth migration, multi-device session tracking, Telegram bot enhancements, and security hardening. *** **Highlights** * **Async-to-Sync WebSocket Migration** — Converted Zerodha, Upstox, and mstock streaming adapters from asyncio `websockets` to sync `websocket-client`, eliminating greenlet conflicts in Docker (Gunicorn + eventlet) deployments * **Market Price Protection (MPP)** — Added automatic MARKET/SL-M to LIMIT/SL conversion with MPP for Zerodha, Kotak, Samco, and Tradejini, protecting traders from extreme price slippage * **Samco 2FA Authentication** — Complete Samco 2FA implementation with OTP, secret key, IP management, and order status normalization * **Shoonya OAuth Migration** — Migrated Shoonya from TOTP login to OAuth (GenAcsTok) authentication with WebSocket and SL-M MPP fixes * **Multi-Device Session Tracking** — Session resume support across devices with active session monitoring and login activity tracking * **Telegram Bot Commands** — New `/closeall` and `/mode` Telegram commands for remote position management and mode switching * **Dynamic Browser Tab Titles** — All 80+ pages now show descriptive titles in browser tabs (e.g., "OI Tracker | OpenAlgo") * **Synthetic Future API Optimization** — Reduced broker API calls from 4+ to 2 using multiquotes batching, cutting Dhan response time from \~8s to \~2s * **Multi-Arch Docker Images** — CI/CD now builds both amd64 and arm64 Docker images on native runners * **Security Patches** — Updated cryptography, axios, vite, Pygments, and lodash-es for CVE fixes *** **New Features** **Async-to-Sync WebSocket Migration** * Convert Zerodha streaming from async websockets to sync websocket-client * Convert Upstox streaming from async websockets to sync websocket-client * Convert mstock streaming from async websockets to sync websocket-client * Reset Upstox and mstock reconnect counters on successful connection **Market Price Protection (MPP)** * Enable market protection for Zerodha market orders with decimal strike preservation * Add MPP for Kotak market orders (MARKET → LIMIT, SL-M → SL with tick-based price protection) * Convert MARKET/SL-M orders to LIMIT/SL with MPP for Samco * Add MPP and fix orderbook status mapping for Tradejini * Guard `trigger_price` float conversion in SL-M MPP handler **Samco 2FA Authentication** * Implement Samco 2FA authentication with OTP, secret key, and IP management * Refactor Samco 2FA to auth table with `aux_param` columns * Fix order status normalization for Cancel/Modify buttons in orderbook * Resolve FD leaks and resource issues in Samco WebSocket streaming * Use equity segment only for Samco funds to avoid double-counting **Shoonya OAuth Migration** * Migrate Shoonya from TOTP login to OAuth (GenAcsTok) authentication * Fix Shoonya WebSocket, SL-M MPP conversion, and circular import * Fix review issues: input validation, null safety, log redaction **Multi-Device Session & Login Activity** * Multi-device session resume and active session tracking * Login activity tracking and security dashboard tabs * Resolve file descriptor and memory leak from uncleaned database sessions **Telegram Bot Enhancements** * Add `/closeall` and `/mode` Telegram bot commands for remote trading control * Fix `/chart` rendering in Docker and eventlet environments **Frontend Enhancements** * Dynamic browser tab titles for all 80+ pages (#881) * Copy and download buttons for Python strategy logs (#1233) * Add aria-labels to TradeBook buttons for accessibility (#1189) **Tradejini Broker Improvements** * Add index symbol normalization and fix WebSocket exchange mapping * Prevent WebSocket FD leaks in quotes, depth, and streaming * Add MPP and fix orderbook status mapping **Smart Order Optimization** * Remove 500ms smart order delay, add position cache + per-symbol lock for faster execution **Infrastructure** * Build multi-arch Docker images (amd64 + arm64) on native runners * Replace `traceback.print_exc()` with `logger.exception()` across all REST API endpoints (#1012) *** **Bug Fixes** * Fix: prevent duplicate order execution race condition in sandbox mode * Fix: optimize synthetic future API — reduce broker API calls from 4+ to 2 using multiquotes (#855) * Fix: return mock response object instead of None for MPP ValueError * Fix: address cubic-dev P1 issues in order\_api and auth\_api * Fix: IIFL Capital index symbol normalization and quotes update * Fix: add IIFL Capital to install script files * Fix: add missing security headers to Flask responses (#1014) * Fix: standardize error logging with `logger.exception()` (#1017) * Fix: adjust font sizes and cell heights in seasonality heatmap * Fix: refine monthly data fetching and processing in seasonality * Fix: update openalgo SDK to 1.0.47, remove numba/llvmlite dependencies *** **Security** * Bump cryptography to 46.0.7 (security patch) * Bump vite to 7.3.2 (security patch) * Bump axios to 1.15.0 (security patches) * Upgrade cryptography, Pygments, and lodash-es for security *** **Contributors** Special thanks to all contributors who made this release possible: * @Kalaiviswa (kalaivani) — Async-to-sync WebSocket migration (Zerodha, Upstox, mstock),
