-# IME Live Data WebSocket Documentation
+# HedgeTech IME Live Data WebSocket API
 
-## Introduction
-
-This WebSocket service provides real-time market data for Iran Mercantile Exchange (IME) contracts.
-
-The service streams live contract updates from Redis Pub/Sub channels and delivers them to connected WebSocket clients.
-
-Two WebSocket endpoints are available:
-
-1. WebSocket By Contract Name
-2. WebSocket By Contract ID
-
-Both endpoints provide the exact same payload structure.  
-The only difference is how contracts are subscribed.
+Professional real-time WebSocket streaming service for Iran Mercantile Exchange (IME) market data.

-# WebSocket Endpoints
+# Overview
 
-# 1. WebSocket By Contract Name
+The HedgeTech IME Live Data WebSocket service provides ultra low-latency real-time streaming market data for IME contracts.
+
+The service is designed for:
+
+- Trading Platforms
+- HFT Systems
+- Algorithmic Trading
+- Quantitative Infrastructure
+- Market Monitoring Systems
+- Real-Time Dashboards
+- Risk Engines
+
+All streams are powered by Redis Pub/Sub infrastructure and asynchronously distributed through FastAPI WebSocket endpoints.

+|---|---|

+| `/live/data/websocket/contract/id` | Subscribe using contract IDs |

+
+# Authentication
+
+All WebSocket endpoints require authentication.
+
+Authentication is performed during the WebSocket handshake phase using Authorization headers.
+
+---
+
+## Authorization Header
+
+```text
+Authorization: Bearer YOUR_ACCESS_TOKEN
+```
+
+---
+
+## Example Authentication Flow
+
+```python
+extra_headers = {
+    "Authorization": "Bearer YOUR_ACCESS_TOKEN"
+}

-# Notes
+# Architecture Notes
 
-- The WebSocket streams real-time market data updates.
-- Each contract is subscribed through a dedicated Redis Pub/Sub stream.
-- Updates are only sent when market data changes.
-- The WebSocket connection remains active until disconnected by the client.
-- Multiple contracts can be subscribed simultaneously.
-- Timestamps are provided in ISO 8601 format.
+- All streams are asynchronous
+- Redis Pub/Sub is used internally
+- Data is pushed only on updates
+- Multiple contracts can be subscribed simultaneously
+- Connections remain active until disconnected
+- ISO 8601 timestamps are used
+- Built for high-throughput market infrastructure
 
 ---
 
-# Recommended Client Strategy
+# Production Recommendations
 
-For production usage, it is recommended to:
+For production-grade integrations:
 
 - Implement automatic reconnect logic
-- Enable heartbeat / ping interval
-- Process messages asynchronously
-- Use internal message queues
-- Configure WebSocket timeout handling
+- Enable WebSocket heartbeat
+- Use asynchronous processing pipelines
+- Queue incoming messages internally
+- Configure proper timeout handling
+- Monitor connection lifecycle
+- Handle transient disconnects gracefully
