Description

• Backend refactoring: Removed server-side HTML rendering (Jinja2Templates, StaticFiles) as frontend is now handled by Svelte, and replaced deprecated _calculate_pnl() with pnl_calculator for accurate PnL calculations

• New API endpoint: Added /api/config/complete endpoint to expose all configuration variables to the frontend

• Real-time stats synchronization: Integrated stats_update WebSocket event emission after position closure for frontend synchronization

• WebSocket improvements: Enhanced connection initialization with better error handling, state synchronization, and retry logic with exponential backoff

• Configuration viewer: Implemented new "Variables en cours" tab in frontend to display all current configuration variables with categorization and formatting

• Telegram status migration: Migrated Telegram status check from REST API to WebSocket-based state requests

• WebSocket URL configuration: Added development/production environment detection for proper WebSocket URL routing (localhost:5000 for dev, proxy for prod)

• Bug fix: Fixed SvelteKit parameter export warning by adding explicit export let params = {} declaration

• Comprehensive documentation: Added WebSocket synchronization audit report (90.5% of fields using WebSocket), configuration verification guide with multiple methods, Streamlit migration analysis, and backend cleanup summary

Security Compliance
⚪	Insecure WebSocket URL Description: Hardcodes ws://localhost:5000 for development which may leak environment assumptions and fail under HTTPS, risking mixed-content or connection exposure if not gated by environment checks. websocket-impl.ts [49-59] Referred Code // En production, utiliser le proxy Vite (window.location.host) const isDev = window.location.hostname === 'localhost' && window.location.port === '3000'; if (isDev) { // Développement: connexion directe au backend url = 'ws://localhost:5000'; } else { // Production: utiliser le proxy ou l'URL de production const protocol = window.location.protocol === 'https:' ? 'wss:' : 'ws:'; const host = window.location.host; url = `${protocol}//${host}`; }
	Sensitive information exposure Description: WebSocket initial status and logs are sent using copies of app_state that may include sensitive runtime data; without explicit filtering this could expose internal details to any connected client. main.py [1956-1993] Referred Code @app.websocket("/ws") async def websocket_endpoint(websocket: WebSocket): """Endpoint WebSocket bidirectionnel natif""" try: await ws_manager.connect(websocket) # 🔥 FIX: Envoyer état initial au client avec gestion d'erreur try: status_data = app_state.copy() if status_data.get('active_position') and hasattr(status_data['active_position'], 'to_dict'): try: status_data['active_position'] = status_data['active_position'].to_dict() except Exception as e: logger.warning(f"⚠️ Erreur conversion position en dict: {e}") status_data['active_position'] = None await ws_manager.send_personal_message({ 'type': 'event', 'event': 'status', 'data': status_data }, websocket) ...

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Security	Secure endpoint exposing all configurations Restrict access to the /api/config/complete endpoint to localhost only to prevent exposing sensitive configuration data. main.py [2591-2609] @app.get("/api/config/complete") -async def api_get_complete_config(): +async def api_get_complete_config(request: Request): """ 🔥 NOUVEAU: Récupérer TOUTES les variables de configuration (TRADING_CONFIG complet) Utile pour vérifier toutes les variables prises en compte par le bot """ + # 🔒 SECURITY: Restrict access to localhost for this sensitive endpoint + if request.client.host != "127.0.0.1" and request.client.host != "localhost": + from fastapi import HTTPException + raise HTTPException(status_code=403, detail="Access forbidden") + from config import TRADING_CONFIG, RISK_CONFIG, CONDITION_WEIGHTS, TREND_BONUS_CONFIG from config import RETRY_CONFIG, CIRCUIT_BREAKER_CONFIG, WEBSOCKET_CONFIG return JSONResponse({ 'trading_config': TRADING_CONFIG, 'risk_config': RISK_CONFIG, 'condition_weights': CONDITION_WEIGHTS, 'trend_bonus_config': TREND_BONUS_CONFIG, 'retry_config': RETRY_CONFIG, 'circuit_breaker_config': CIRCUIT_BREAKER_CONFIG, 'websocket_config': WEBSOCKET_CONFIG, 'timestamp': time.time() }) Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a security risk in a newly added endpoint and proposes a simple, effective mitigation to prevent potential information leakage.	Medium
High-level	Consider Streamlit for a simpler architecture To simplify the architecture, consider migrating from the current FastAPI+Svelte stack to Streamlit. This would unify the project into a single Python application, simplifying development and maintenance. Examples: docs/STREAMLIT_ANALYSIS.md [1-541] # 🔍 Analyse : Migration vers Streamlit ## 📊 Vue d'ensemble **Streamlit** est un framework Python qui permet de créer des interfaces web rapidement, **sans frontend séparé** (pas de Svelte/React/Vue). --- ## 🏗️ Architecture Actuelle vs Streamlit ...

Medium
General	Use environment variables for WebSocket URL Use Vite environment variables (e.g., VITE_WS_URL) to configure the WebSocket URL instead of hardcoding it for development. frontend/src/lib/utils/websocket-impl.ts [45-65] constructor(url: string = '') { // Détecter l'URL depuis window.location si non fournie if (!url) { - // 🔥 FIX: En développement, utiliser directement le backend (port 5000) - // En production, utiliser le proxy Vite (window.location.host) - const isDev = window.location.hostname === 'localhost' && window.location.port === '3000'; - if (isDev) { - // Développement: connexion directe au backend - url = 'ws://localhost:5000'; + // 🔥 FIX: Utiliser les variables d'environnement Vite pour une configuration flexible + // VITE_WS_URL est défini dans .env.development (e.g., ws://localhost:5000) + // En production, il n'est pas défini, on utilise donc l'hôte actuel. + if (import.meta.env.VITE_WS_URL) { + url = import.meta.env.VITE_WS_URL; } else { // Production: utiliser le proxy ou l'URL de production const protocol = window.location.protocol === 'https:' ?

	Optimize fetching of Telegram status Optimize fetching the Telegram status by creating a dedicated, lightweight WebSocket request instead of fetching the entire application state. frontend/src/lib/components/NotificationSettings.svelte [32-54] // 🔥 MIGRATION COMPLÈTE: Vérifier le statut Telegram via WebSocket async function checkTelegramStatus() { try { const { getWebSocket, sendRequestViaWS } = await import('$lib/utils/websocket'); const ws = getWebSocket(); if (ws && ws.connected) { - const response = await sendRequestViaWS('state', {}); - const stateData = response?.data || response; - // Vérifier si Telegram est configuré (via backend) - // Le backend devrait exposer cette info dans state.config - if (stateData && stateData.config) { - telegramStatus = stateData.config.telegram_enabled ?
