# Changelog
## 2025-10-31 - 2.1.0 - feat(stocks)
Add unified stock data API (getData) with historical/OHLCV support, smart caching and provider enhancements
- Introduce discriminated union request types (IStockDataRequest) and a unified getData() method (replaces legacy getPrice/getPrices for new use cases)
- Add OHLCV fields (open, high, low, volume, adjusted) and metadata (dataType, fetchedAt) to IStockPrice
- Implement data-type aware smart caching with TTLs (historical = never expire, EOD = 24h, live = 30s, intraday matches interval)
- Extend StockPriceService: new getData(), data-specific cache keys, cache maxEntries increased (default 10000), and TTL-aware add/get cache logic
- Enhance Marketstack provider: unified fetchData(), historical date-range retrieval with pagination, exchange filtering, batch current fetch, OHLCV mapping, and intraday placeholder
- Update Yahoo provider to include dataType and fetchedAt (live data) and maintain legacy fetchPrice/fetchPrices compatibility
- Add/adjust tests to cover unified API, historical retrieval, OHLCV presence and smart caching behavior; test setup updated to require explicit OpenData directory paths
- Update README to document v2.1 changes, migration examples, and new stock provider capabilities
## 2025-10-31 - 2.0.0 - BREAKING CHANGE(OpenData)
Require explicit directory paths for OpenData (nogit/download/germanBusinessData); remove automatic .nogit creation; update HandelsRegister, JsonlDataProcessor, tests and README.

Access live stock prices, cryptocurrencies, forex, commodities AND comprehensive German company data - all through a single, unified API.
## ⚠️ Breaking Change in v2.0
## ⚠️ Breaking Changes
### v2.1 - Enhanced Stock Market API (Current)
**The stock market API has been significantly enhanced with a new unified request system.**
**What Changed:**
- New discriminated union request types (`IStockDataRequest`)
- Enhanced `IStockPrice` interface with OHLCV data and metadata
- New `getData()` method replaces legacy `getPrice()` and `getPrices()`
- Historical data support with date ranges
- Exchange filtering via MIC codes
- Smart caching with data-type aware TTL
**Migration:**
```typescript
// OLD (v2.0 and earlier)
const price = await service.getPrice({ ticker: 'AAPL' });
const prices = await service.getPrices({ tickers: ['AAPL', 'MSFT'] });
// NEW (v2.1+) - Unified API
const price = await service.getData({ type: 'current', ticker: 'AAPL' });
const prices = await service.getData({ type: 'batch', tickers: ['AAPL', 'MSFT'] });
// NEW - Historical data
const history = await service.getData({
type: 'historical',
ticker: 'AAPL',
from: new Date('2024-01-01'),
to: new Date('2024-12-31')
});
// NEW - Exchange filtering
const price = await service.getData({
type: 'current',
ticker: 'VOD',
exchange: 'XLON' // London Stock Exchange
});
```
**Note:** Legacy `getPrice()` and `getPrices()` methods still work but are deprecated.
### v2.0 - Directory Configuration
**Directory paths are now MANDATORY when using German business data features.** The package no longer creates `.nogit/` directories automatically. You must explicitly configure all directory paths when instantiating `OpenData`:

## Advanced Examples
### Phase 1: Historical Data Analysis
Fetch and analyze historical price data:
```typescript
// Get 1 year of historical data
const history = await stockService.getData({
type: 'historical',
ticker: 'AAPL',
from: new Date('2024-01-01'),
to: new Date('2024-12-31'),
sort: 'DESC' // Newest first (default)
});
// Calculate statistics
const prices = history.map(p => p.price);
const high52Week = Math.max(...prices);
const low52Week = Math.min(...prices);
const avgPrice = prices.reduce((a, b) => a + b) / prices.length;
console.log(`52-Week Analysis for AAPL:`);
console.log(`High: $${high52Week.toFixed(2)}`);
console.log(`Low: $${low52Week.toFixed(2)}`);
console.log(`Average: $${avgPrice.toFixed(2)}`);
console.log(`Days: ${history.length}`);
// Calculate daily returns
for (let i = 0; i < history.length - 1; i++) {
const todayPrice = history[i].price;
const yesterdayPrice = history[i + 1].price;
const dailyReturn = ((todayPrice - yesterdayPrice) / yesterdayPrice) * 100;
console.log(`${history[i].timestamp.toISOString().split('T')[0]}: ${dailyReturn.toFixed(2)}%`);
}
```
### Phase 1: Exchange-Specific Trading
Compare prices across different exchanges:
```typescript
// Vodafone trades on both London and NYSE
const exchanges = [
{ mic: 'XLON', name: 'London Stock Exchange' },
{ mic: 'XNYS', name: 'New York Stock Exchange' }
];
for (const exchange of exchanges) {
try {
const price = await stockService.getData({
type: 'current',
ticker: 'VOD',
exchange: exchange.mic
});
console.log(`${exchange.name}:`);
console.log(` Price: ${price.price} ${price.currency}`);
console.log(` Volume: ${price.volume?.toLocaleString()}`);
console.log(` Exchange: ${price.exchangeName}`);
} catch (error) {
console.log(`${exchange.name}: Not available`);
}
}
```
### Phase 1: OHLCV Technical Analysis
Use OHLCV data for technical indicators:
```typescript
const history = await stockService.getData({
type: 'historical',
ticker: 'TSLA',
from: new Date('2024-11-01'),
to: new Date('2024-11-30')
});
// Calculate daily trading range
for (const day of history) {
const range = day.high - day.low;
const rangePercent = (range / day.low) * 100;
console.log(`${day.timestamp.toISOString().split('T')[0]}:`);
console.log(` Open: $${day.open}`);
console.log(` High: $${day.high}`);
console.log(` Low: $${day.low}`);
console.log(` Close: $${day.price}`);
console.log(` Volume: ${day.volume?.toLocaleString()}`);
console.log(` Range: $${range.toFixed(2)} (${rangePercent.toFixed(2)}%)`);
}
// Calculate Simple Moving Average (SMA)
const calculateSMA = (data: IStockPrice[], period: number) => {
const sma: number[] = [];
for (let i = period - 1; i < data.length; i++) {
const sum = data.slice(i - period + 1, i + 1)
.reduce((acc, p) => acc + p.price, 0);
sma.push(sum / period);
}
return sma;
};
const sma20 = calculateSMA(history, 20);
const sma50 = calculateSMA(history, 50);
console.log(`20-day SMA: $${sma20[0].toFixed(2)}`);
console.log(`50-day SMA: $${sma50[0].toFixed(2)}`);
```
### Phase 1: Smart Caching Performance
Leverage smart caching for efficiency:
```typescript
// Historical data is cached FOREVER (never changes)
console.time('First historical fetch');
const history1 = await stockService.getData({
type: 'historical',
ticker: 'AAPL',
from: new Date('2024-01-01'),
to: new Date('2024-12-31')
});
console.timeEnd('First historical fetch');
// Output: First historical fetch: 2341ms
console.time('Second historical fetch (cached)');
const history2 = await stockService.getData({
type: 'historical',
ticker: 'AAPL',
from: new Date('2024-01-01'),
to: new Date('2024-12-31')
});
console.timeEnd('Second historical fetch (cached)');
// Output: Second historical fetch (cached): 2ms (1000x faster!)
// EOD data cached for 24 hours
const currentPrice = await stockService.getData({
type: 'current',
ticker: 'MSFT'
});
// Subsequent calls within 24h served from cache
// Cache statistics
console.log(`Cache size: ${stockService['cache'].size} entries`);
```
