# DQN RL-based Sensitivity Learning & 300s Data Preloading Summary

## Overview
This document summarizes the implementation of DQN RL-based sensitivity learning and 300s data preloading features that make the trading system more adaptive and responsive.

## 🧠 DQN RL-based Sensitivity Learning

### Core Concept
The system now uses a Deep Q-Network (DQN) to learn optimal sensitivity levels for trading decisions based on market conditions and trade outcomes. After each completed trade, the system evaluates the performance and creates a learning case for the DQN agent.

### Implementation Details

#### 1. Sensitivity Levels (5 levels: 0-4)
```python
sensitivity_levels = {
    0: {'name': 'very_conservative', 'open_threshold_multiplier': 1.5, 'close_threshold_multiplier': 2.0},
    1: {'name': 'conservative', 'open_threshold_multiplier': 1.2, 'close_threshold_multiplier': 1.5},
    2: {'name': 'medium', 'open_threshold_multiplier': 1.0, 'close_threshold_multiplier': 1.0},
    3: {'name': 'aggressive', 'open_threshold_multiplier': 0.8, 'close_threshold_multiplier': 0.7},
    4: {'name': 'very_aggressive', 'open_threshold_multiplier': 0.6, 'close_threshold_multiplier': 0.5}
}
```

#### 2. Trade Tracking System
- **Active Trades**: Tracks open positions with entry conditions
- **Completed Trades**: Records full trade lifecycle with outcomes
- **Learning Queue**: Stores DQN training cases from completed trades

#### 3. DQN State Vector (15 features)
- Market volatility (normalized)
- Price momentum (5-period)
- Volume ratio
- RSI indicator
- MACD signal
- Bollinger Band position
- Recent price changes (5 periods)
- Current sensitivity level
- Recent performance metrics (avg P&L, win rate, avg duration)

#### 4. Reward Calculation
```python
def _calculate_sensitivity_reward(self, completed_trade):
    base_reward = pnl_pct * 10  # Scale P&L percentage
    
    # Duration factor
    if duration < 300: duration_factor = 0.8      # Too quick
    elif duration < 1800: duration_factor = 1.2   # Good for scalping
    elif duration < 3600: duration_factor = 1.0   # Acceptable
    else: duration_factor = 0.7                   # Too slow
    
    # Confidence factor
    conf_factor = (entry_conf + exit_conf) / 2 if profitable else exit_conf
    
    final_reward = base_reward * duration_factor * conf_factor
    return np.clip(final_reward, -2.0, 2.0)
```

#### 5. Dynamic Threshold Adjustment
- **Opening Positions**: Higher thresholds (more conservative)
- **Closing Positions**: Lower thresholds (more sensitive to exit signals)
- **Real-time Adaptation**: DQN continuously adjusts sensitivity based on market conditions

### Files Modified
- `core/enhanced_orchestrator.py`: Added sensitivity learning methods
- `core/config.py`: Added `confidence_threshold_close` parameter
- `web/scalping_dashboard.py`: Added sensitivity info display
- `NN/models/dqn_agent.py`: Existing DQN agent used for sensitivity learning

## 📊 300s Data Preloading

### Core Concept
The system now preloads 300 seconds worth of data for all symbols and timeframes on first load, providing better initial performance and reducing latency for trading decisions.

### Implementation Details

#### 1. Smart Preloading Logic
```python
def _should_preload_data(self, symbol: str, timeframe: str, limit: int) -> bool:
    # Check if we already have cached data
    if cached_data exists and len(cached_data) > 0:
        return False
    
    # Calculate candles needed for 300s
    timeframe_seconds = self.timeframe_seconds.get(timeframe, 60)
    candles_in_300s = 300 // timeframe_seconds
    
    # Preload if beneficial
    return candles_in_300s > limit or timeframe in ['1s', '1m']
```

#### 2. Timeframe-Specific Limits
- **1s timeframe**: Max 300 candles (5 minutes)
- **1m timeframe**: Max 60 candles (1 hour)
- **Other timeframes**: Max 500 candles
- **Minimum**: Always at least 100 candles

#### 3. Preloading Process
1. Check if data already exists (cache or memory)
2. Calculate optimal number of candles for 300s
3. Fetch data from Binance API
4. Add technical indicators
5. Cache data for future use
6. Store in memory for immediate access

#### 4. Performance Benefits
- **Faster Initial Load**: Charts populate immediately
- **Reduced API Calls**: Bulk loading vs individual requests
- **Better User Experience**: No waiting for data on first load
- **Improved Trading Decisions**: More historical context available

### Files Modified
- `core/data_provider.py`: Added preloading methods
- `web/scalping_dashboard.py`: Integrated preloading in initialization

## 🎨 Enhanced Dashboard Features

### 1. Color-Coded Position Display
- **LONG positions**: Green text with `[LONG]` prefix
- **SHORT positions**: Red text with `[SHORT]` prefix
- **Format**: `[SIDE] size @ $entry_price | P&L: $unrealized_pnl`

### 2. Enhanced Model Training Status
Now displays three columns:
- **RL Training**: Queue size, win rate, actions
- **CNN Training**: Perfect moves, confidence, retrospective learning
- **DQN Sensitivity**: Current level, completed trades, learning queue, thresholds

### 3. Sensitivity Learning Info
```python
{
    'level_name': 'MEDIUM',           # Current sensitivity level
    'completed_trades': 15,           # Number of completed trades
    'learning_queue_size': 8,         # DQN training queue size
    'open_threshold': 0.600,          # Current opening threshold
    'close_threshold': 0.250          # Current closing threshold
}
```
