# Neural Trader
|
||||
|
||||
A production-ready neural trading system combining state-of-the-art machine learning techniques for automated trading, sports betting, and portfolio management.
|
||||
|
||||
## Introduction
|
||||
|
||||
Neural Trader is a comprehensive algorithmic trading framework that integrates four core AI/ML engines:
|
||||
|
||||
- **Fractional Kelly Criterion** - Optimal position sizing with risk-adjusted bet scaling
|
||||
- **Hybrid LSTM-Transformer** - Deep learning price prediction combining temporal and attention mechanisms
|
||||
- **DRL Portfolio Manager** - Reinforcement learning ensemble (PPO/SAC/A2C) for dynamic asset allocation
|
||||
- **Sentiment Alpha Pipeline** - Real-time sentiment analysis for alpha generation
|
||||
|
||||
Built entirely in JavaScript with zero external ML dependencies, Neural Trader achieves sub-millisecond latency suitable for high-frequency trading applications.
|

|
||||
## Features
|
||||
|
||||
### Core Production Engines
|
||||
|
||||
#### 1. Fractional Kelly Criterion Engine
|
||||
```javascript
|
||||
import { KellyCriterion, TradingKelly } from './production/fractional-kelly.js';
|
||||
|
||||
const kelly = new KellyCriterion();
|
||||
const stake = kelly.calculateStake(9000, 0.55, 2.0, 0.2); // 1/5th Kelly
|
||||
// → $180 recommended stake (2% of bankroll)
|
||||
```
|
||||
|
||||
- Full, Half, Quarter, and custom fractional Kelly
|
||||
- ML model calibration support
|
||||
- Multi-bet portfolio optimization
|
||||
- Risk of ruin analysis
|
||||
- Sports betting and trading position sizing
|
||||
- Optimal leverage calculation
|
||||
|
||||
#### 2. Hybrid LSTM-Transformer Predictor
|
||||
```javascript
|
||||
import { HybridLSTMTransformer } from './production/hybrid-lstm-transformer.js';
|
||||
|
||||
const model = new HybridLSTMTransformer({
|
||||
lstm: { hiddenSize: 64, layers: 2 },
|
||||
transformer: { heads: 4, layers: 2 }
|
||||
});
|
||||
const prediction = model.predict(candles);
|
||||
// → { signal: 'BUY', confidence: 0.73, direction: 'bullish' }
|
||||
```
|
||||
|
||||
- Multi-layer LSTM with peephole connections
|
||||

|
||||
- 10 built-in technical features (RSI, momentum, volatility, etc.)
|
||||

|
||||
|
||||
#### 3. DRL Portfolio Manager

|
||||
|
||||
const manager = new DRLPortfolioManager({ numAssets: 10 });
|
||||
await manager.train(marketData, { episodes: 100 });
|
||||
const allocation = manager.getAction(currentState);
|
||||
// → [0.15, 0.12, 0.08, ...] optimal weights
|
||||
```
|
||||
|
||||
- PPO (Proximal Policy Optimization) agent

|
||||
|
||||
const stream = new SentimentStreamProcessor();
|
||||
stream.process({ symbol: 'AAPL', text: newsArticle, source: 'news' });
|
||||
const signal = stream.getSignal('AAPL');
|
||||
// → { signal: 'BUY', strength: 'high', probability: 0.62 }
|
||||
```
|
||||

## RuVector Integration Points
|
||||
|
||||
These examples demonstrate how to leverage RuVector with neural-trader:
|
||||
|
||||
1. **Pattern Storage**: Store historical trading patterns as vectors for similarity search
|
||||
2. **Signal Caching**: Cache trading signals with vector embeddings for quick retrieval
|
||||
3. **Model Weights**: Store neural network checkpoints for versioning
|
||||
4. **News Embeddings**: Index news articles with sentiment embeddings
|
||||
5. **Trade Decision Logging**: Log decisions with vector search for analysis
