This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (meridianalgo-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

npm install meridianalgo-js

Basic Usage

import { UltraPrecisionPredictor, FeatureEngineer } from 'meridianalgo-js';

// Create predictor instance
const predictor = new UltraPrecisionPredictor({
  targetAccuracy: 0.01, // Target 1% error rate
  features: ['bollinger', 'rsi', 'macd', 'volatility'],
  models: ['randomForest', 'neuralNetwork', 'ensemble']
});

// Sample market data
const marketData = [
  { open: 100, high: 102, low: 99, close: 101, volume: 10000 },
  { open: 101, high: 103, low: 100, close: 102, volume: 12000 },
  // ... more data
];

// Train the model
await predictor.train(marketData);

// Make predictions
const prediction = await predictor.predict(marketData.slice(-10));
console.log('Next price prediction:', prediction);

Advanced Feature Engineering

import { FeatureEngineer } from 'meridianalgo-js';

const engineer = new FeatureEngineer({
  generators: [
    'advancedBollinger',    // Golden ratio Bollinger Bands
    'multiRSI',             // Multi-timeframe RSI analysis
    'microstructure',       // Market microstructure features
    'volatilityAnalysis',   // Advanced volatility modeling
    'harmonicAnalysis'      // Frequency domain analysis
  ]
});

// Generate 1000+ features from basic OHLCV data
const features = await engineer.generateFeatures(marketData);
console.log(`Generated ${features.columns.length} features`);

📈 Advanced Examples

// Start real-time predictions
tradingSystem.start((prediction) => {
  console.log('Real-time prediction:', {
    price: prediction.price,
    confidence: prediction.confidence,
    direction: prediction.direction,
    risk: prediction.risk
  });
});

Portfolio Optimization

import { PortfolioOptimizer, RiskAnalyzer } from 'meridianalgo-js';

  constraints: {
    maxWeight: 0.4,
    minWeight: 0.05,
    maxVolatility: 0.15
  }
});

const portfolio = await optimizer.optimize(historicalData);
console.log('Optimal weights:', portfolio.weights);
console.log('Expected return:', portfolio.expectedReturn);
console.log('Risk (volatility):', portfolio.risk);

Market Regime Detection

import { RegimeDetector, MarketAnalyzer } from 'meridianalgo-js';

const regimeDetector = new RegimeDetector({
