/**
 * Marketstack API v2 Provider - Professional Plan with Intelligent Intraday Support
 * Documentation: https://docs.apilayer.com/marketstack/docs/marketstack-api-v2-v-2-0-0
 *
 * Features:
 * - Intelligent endpoint selection based on market hours
 * - Real-time intraday pricing with multiple intervals (1min, 5min, 10min, 15min, 30min, 1hour)
 * - End-of-Day (EOD) stock prices with historical data
 * - Market state detection (PRE, REGULAR, POST, CLOSED)
 * - Exchange filtering via MIC codes (XNAS, XNYS, XLON, etc.)
 * - Supports 500,000+ tickers across 72+ exchanges worldwide
 * - OHLCV data (Open, High, Low, Close, Volume)
 * - Pagination for large datasets
 * - Automatic fallback from intraday to EOD on errors
 * - Requires API key authentication
 *
 * Intelligent Endpoint Selection:
 * - During market hours (PRE/REGULAR/POST): Uses intraday endpoints for fresh data
 * - After market close (CLOSED): Uses EOD endpoints to save API credits
 * - Automatic fallback to EOD if intraday fails (rate limits, plan restrictions, etc.)
 *
 * Rate Limits:
 * - Free Plan: 100 requests/month (EOD only)
 * - Basic Plan: 10,000 requests/month (EOD only)
 * - Professional Plan: 100,000 requests/month (intraday + EOD)
 *
 * Intraday Access:
 * - Intervals below 15min (1min, 5min, 10min) require Professional Plan or higher
 * - Real-time data from IEX Exchange for US tickers
 * - Symbol formatting: Periods replaced with hyphens for intraday (BRK.B → BRK-B)
