 ## Project Overview
 
-CoinTrader is a Python asyncio-based automated cryptocurrency trading bot for Binance Futures. It trades XRPUSDT on 15-minute candles, using BTC/ETH as correlation features. The system has 5 layers: Data (WebSocket streams) → Signal (technical indicators) → ML Filter (ONNX/LightGBM) → Execution & Risk → Event/Alert (Discord).
+CoinTrader is a Python asyncio-based automated cryptocurrency trading bot for Binance Futures. It supports multi-symbol simultaneous trading (XRP, TRX, DOGE etc.) on 15-minute candles, using BTC/ETH as correlation features. The system has 5 layers: Data (WebSocket streams) → Signal (technical indicators) → ML Filter (ONNX/LightGBM) → Execution & Risk → Event/Alert (Discord).

 ## Architecture

+**Entry point**: `main.py` → creates `Config` → shared `RiskManager` → per-symbol `TradingBot` instances → `asyncio.gather()`
+
+**Multi-symbol architecture**: Each symbol gets its own `TradingBot` instance with independent `Exchange`, `MLFilter`, and `DataStream`. The `RiskManager` is shared as a singleton across all bots, enforcing global daily loss limits and same-direction position limits via `asyncio.Lock`.
 
 **5-layer data flow on each 15m candle close:**
-1. `src/data_stream.py` — Combined WebSocket for XRP/BTC/ETH, deque buffers (200 candles each)
+1. `src/data_stream.py` — Combined WebSocket for primary+correlation symbols, deque buffers (200 candles each)
 2. `src/indicators.py` — RSI, MACD, BB, EMA, StochRSI, ATR; weighted signal aggregation → LONG/SHORT/HOLD
 3. `src/ml_filter.py` + `src/ml_features.py` — 26-feature extraction (ADX + OI 파생 피처 포함), ONNX priority > LightGBM fallback, threshold ≥ 0.55
-4. `src/exchange.py` + `src/risk_manager.py` — Dynamic margin, MARKET orders with SL/TP, daily loss limit (5%)

-**Parallel execution**: `user_data_stream` runs independently via `asyncio.gather()` alongside candle processing.
+**Parallel execution**: Per-symbol bots run independently via `asyncio.gather()`. Each bot's `user_data_stream` also runs in parallel.

+**Model/data directories**: `models/{symbol}/` and `data/{symbol}/` for per-symbol models. Falls back to `models/` root if symbol dir doesn't exist.
