# 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
|
|
- Multi-head self-attention transformer
|
|

|
|
|
|
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
|
|
```
|
|
|
|

|
|
const stream = new SentimentStreamProcessor();
|
|
stream.process({ symbol: 'AAPL', text: newsArticle, source: 'news' });
|
|
const signal = stream.getSignal('AAPL');
|
