+```
+
+---
+
+## 🎯 پرامپت جامع برای ارتقای پروژه
+
+### مرحله 1: ارتقای Smart Proxy Manager
+
+```
+من یک سیستم جمع‌آوری داده کریپتو دارم که باید از proxy و DNS هوشمند برای دسترسی به Binance و CoinGecko استفاده کنه (این APIها در برخی کشورها فیلتر هستند).
+
+**نیازمندی‌ها:**
+
+1. **Smart Proxy System** با قابلیت‌های زیر:
+   - ادغام با free proxy providers مثل ProxyScrape، Free-Proxy-List
+   - Auto-refresh و validation پروکسی‌ها هر 5 دقیقه
+   - Health check برای همه proxies
+   - Load balancing هوشمند بین proxies
+   - Fallback به direct connection در صورت عدم دسترسی proxy
+
+2. **Dynamic DNS Resolution**:
+   - استفاده از DoH (DNS over HTTPS) با Cloudflare/Google
+   - DNS caching برای بهینه‌سازی
+   - Fallback DNS servers
+   - Automatic retry با DNS مختلف
+
+3. **Provider-Specific Routing**:
+   - تشخیص اتوماتیک نیاز به proxy (برای Binance و CoinGecko)
+   - مسیریابی مستقیم برای provider های دیگر
+   - Configurable routing rules
+
+**کدی که باید بهبود داده بشه:**
+- `/core/smart_proxy_manager.py` - سیستم فعلی ناقص است
+- نیاز به ادغام واقعی با proxy providers
+- پیاده‌سازی DNS over HTTPS
+- افزودن retry logic و circuit breaker pattern
+
+**خروجی مورد نیاز:**
+کد کامل و عملیاتی برای `smart_proxy_manager.py` که:
+- از API های رایگان proxy استفاده کند
+- Health check اتوماتیک داشته باشد
+- Load balancing هوشمند انجام دهد
+- Logging و metrics کامل داشته باشد
+```
+
+---
+
+### مرحله 2: ارتقای رابط کاربری به React/Next.js
+
+```
+رابط کاربری فعلی من HTML/CSS/JS ساده است. می‌خواهم آن را به یک داشبورد مدرن React/Next.js ارتقا دهم.
+
+**نیازمندی‌های UI/UX:**
+
+1. **داشبورد اصلی** شامل:
+   - Real-time price ticker برای top 20 coins
+   - نمودارهای TradingView/Recharts برای نمایش OHLC
+   - News feed با فیلتر sentiment
+   - Provider health status
+   - Search و filter پیشرفته
+
+2. **صفحه تحلیل** با:
+   - نمودارهای تکنیکال (RSI, MACD, BB)
+   - On-chain metrics
+   - Social sentiment analysis
+   - AI-powered predictions
+
+3. **صفحه Providers** برای:
+   - نمایش وضعیت همه providers
+   - Test connectivity
+   - Enable/disable providers
+   - نمایش rate limits و usage
+
+4. **تم دارک/لایت** با طراحی مدرن Glassmorphism
+
+**استک فنی پیشنهادی:**
+```typescript
+// Tech Stack
+{
+  "framework": "Next.js 14 (App Router)",
+  "ui": "Shadcn/ui + Tailwind CSS",
+  "charts": "Recharts + TradingView Lightweight Charts",
+  "state": "Zustand",
+  "api": "SWR for data fetching",
+  "websocket": "Socket.io-client",
+  "icons": "Lucide React"
+}
+```
+
+**خروجی مورد نیاز:**
+ساختار کامل پروژه Next.js شامل:
+- Component structure
+- API routes integration با FastAPI backend
+- Real-time WebSocket integration
+- Responsive design
+- Dark/Light theme
+- Persian RTL support (در صورت نیاز)
+```
+
+---
+
+### مرحله 3: بهبود System Architecture
+
+```
+می‌خواهم معماری سیستم را بهینه کنم تا scalable و maintainable باشد.
+
+**بهبودهای مورد نیاز:**
+
+1. **Caching Strategy**:
+```python
+# Redis برای caching
+cache_config = {
+    "price_data": "60 seconds TTL",
+    "ohlcv_data": "5 minutes TTL",
+    "news": "10 minutes TTL",
+    "provider_health": "30 seconds TTL"
+}
+```
+
+2. **Rate Limiting** با استفاده از `slowapi`:
+```python
+# Per-endpoint rate limits
+rate_limits = {
+    "/api/prices": "100/minute",
+    "/api/ohlcv": "50/minute",
+    "/api/news": "30/minute",
+    "/ws/*": "No limit (WebSocket)"
+}
+```
+
+3. **Background Workers** برای:
+- جمع‌آوری داده‌های OHLCV هر 1 دقیقه
+- Scraping news هر 5 دقیقه
+- Provider health checks هر 30 ثانیه
+- Database cleanup هر 24 ساعت
+
+4. **Error Handling & Resilience**:
+```python
+# Circuit breaker pattern
+from circuitbreaker import circuit
+
+@circuit(failure_threshold=5, recovery_timeout=60)
+async def fetch_from_provider(provider_name: str):
+    # Implementation with retry logic
+    pass
+```
+
+**خروجی مورد نیاز:**
+- کد کامل برای workers با APScheduler/Celery
+- Redis integration برای caching
+- Circuit breaker implementation
+- Comprehensive error handling
+```
+
+---
+
+### مرحله 4: Monitoring و Observability
+
+```
+نیاز به یک سیستم جامع monitoring دارم.
+
+**نیازمندی‌ها:**
+
+1. **Metrics Collection**:
+```python
+# Metrics to track
+metrics = {
+    "api_requests_total": "Counter",
+    "api_response_time": "Histogram",
+    "provider_requests": "Counter by provider",
+    "provider_failures": "Counter",
+    "cache_hits": "Counter",
+    "active_websocket_connections": "Gauge"
+}
+```
+
+2. **Logging با Structured Logs**:
+```python
+import structlog
+
+logger = structlog.get_logger()
+logger.info("provider_request", 
+    provider="binance", 
+    endpoint="/api/v3/ticker", 
+    duration_ms=150,
+    status="success"
+)
+```
+
+3. **Health Checks**:
+```python
+@app.get("/health")
+async def health_check():
+    return {
+        "status": "healthy",
+        "providers": {
+            "binance": "ok",
+            "coingecko": "ok",
+            ...
+        },
+        "database": "connected",
+        "cache": "connected",
+        "uptime": "2d 5h 30m"
+    }
+```
+
+**خروجی مورد نیاز:**
+- کد monitoring با Prometheus metrics
+- Structured logging setup
+- Health check endpoints
+- Dashboard template برای Grafana (optional)
+```
+
+---
+
+### مرحله 5: Testing و Documentation
+
+```
+نیاز به test coverage و documentation جامع دارم.
+
+**Testing Requirements:**
+
+1. **Unit Tests** برای:
+```python
+# Test examples
+def test_proxy_manager():
+    """Test proxy rotation and health checks"""
+    pass
+
+def test_data_collectors():
+    """Test each provider's data collection"""
+    pass
+
+def test_api_endpoints():
+    """Test all FastAPI endpoints"""
+    pass
+```
+
+2. **Integration Tests**:
+```python
+async def test_end_to_end_flow():
+    """Test complete data flow from provider to API"""
+    pass
+```
+
+3. **Load Testing** با locust:
+```python
+from locust import HttpUser, task
+
+class CryptoAPIUser(HttpUser):
+    @task
+    def get_prices(self):
+        self.client.get("/api/prices")
+```
+
+**Documentation:**

+# 🚀 آپلود سریع به Hugging Face Spaces
+
+## روش 1: از طریق Hugging Face Web Interface
+
+### مرحله 1: ایجاد یا انتخاب Space
+1. برو به: https://huggingface.co/spaces
+2. اگر Space جدید می‌خواهی: **"Create new Space"**
+   - Name: `Datasourceforcryptocurrency` (یا نام دلخواه)
+   - SDK: **Docker** ⚠️ (خیلی مهم!)
+   - Visibility: Public
+3. اگر Space موجود است: برو به Space → Settings → Repository
+
+### مرحله 2: Clone و Push
+```bash
+# Clone Space (اگر Space جدید است)
+git clone https://huggingface.co/spaces/YOUR_USERNAME/YOUR_SPACE_NAME
+cd YOUR_SPACE_NAME
+
+# یا اگر Space موجود است
+cd "c:\Users\Dreammaker\Videos\idm downlod\crypto-dt-source-main (4)\crypto-dt-source-main"
+
+# کپی کردن فایل‌ها به Space
+# (یا از Git push استفاده کن - روش 2)
+```
+
+## روش 2: از طریق Git Push (پیشنهادی)
+
+### مرحله 1: اضافه کردن Remote
+```bash
+cd "c:\Users\Dreammaker\Videos\idm downlod\crypto-dt-source-main (4)\crypto-dt-source-main"
+
+# برای Space جدید
+git remote add hf https://huggingface.co/spaces/YOUR_USERNAME/YOUR_SPACE_NAME
+
+# یا برای Space موجود
+git remote add hf https://huggingface.co/spaces/Really-amin/Datasourceforcryptocurrency
+```
+
+### مرحله 2: Commit و Push
+```bash
+# اضافه کردن همه فایل‌ها
+git add .
+
+# Commit
+git commit -m "Complete project: Real API data only, no mock data"
+
+# Push به Hugging Face
+git push hf main
+```
+
+## ⚙️ تنظیمات مهم در Hugging Face
+
+بعد از push، در Settings → Variables اضافه کن:
+```
+HF_API_TOKEN=your_huggingface_token_here
+```
+
+**نکته امنیتی**: هرگز توکن واقعی را در فایل‌های کد یا مستندات قرار ندهید. از متغیرهای محیطی استفاده کنید.
+
+## ✅ چک‌لیست
+
+- [x] Dockerfile موجود است
+- [x] requirements.txt به‌روز است  
+- [x] hf_unified_server.py entry point است
+- [x] همه mock data حذف شده
+- [x] README.md موجود است
+
+## 🔍 بررسی بعد از آپلود
+
+1. **Build Logs**: Space → Logs
+2. **Health**: `https://YOUR_SPACE.hf.space/api/health`
+3. **UI**: `https://YOUR_SPACE.hf.space/`
+
+---
+
+**نکته**: اگر Space قبلاً وجود دارد (`Datasourceforcryptocurrency`)، از همان استفاده کن و فقط push کن.

-$env:HF_TOKEN
-$env:HF_MODE
-```
-
-**Solution:** Use `run_server.ps1` which sets them automatically
-
-### Charts not displaying?
-
-**Check:** Browser console (F12) for errors  
-**Solution:** Make sure internet is connected (CDN for Chart.js)
-
-### Trading pairs not showing?
-
-**Check:** Console should show "Loaded 300 trading pairs"  
-**Solution:** File `trading_pairs.txt` must exist in root
-
-### No news articles?
-
-**Reason:** Database is empty  
-**Solution:** Use "News & Financial Sentiment Analysis" to add news

+# Crypto Data Source (HF Space)
+
+این پروژه یک **API + داشبورد** برای داده‌های رمزارز است و برای اجرا روی **Hugging Face Spaces (Docker)** آماده شده.
+
+## اجرا روی Hugging Face Space
+
+- **Entry-point (Docker)**: `hf_unified_server:app`
+- **Port**: `7860`
+- **Health**: `GET /api/health`
+
+## Endpointهای مهم برای UI
+
+- `GET /api/ai/signals` (سیگنال‌ها)
+- `POST /api/ai/decision` (تصمیم AI Analyst)
+- `POST /api/sentiment/analyze` (تحلیل احساسات متن)
+
+## نکته مهم درباره “مدل‌ها”
+
+Endpointهای AI در `hf_unified_server.py` از این ماژول استفاده می‌کنند:
+- `backend/services/real_ai_models.py` → اجرای **واقعی** مدل‌ها از طریق HuggingFace Inference (با fallback امن)
+
+## مستندات قدیمی (مرتب‌شده)
+
+فایل‌های توضیحی/گزارش‌های قبلی به این مسیر منتقل شدند:
+- `docs/legacy/`
+
