var bars = await marketstackService.GetStockEodBars(appleSymbol, fromDate, toDate); Parallel Requests:
Parallel requests are supported using the Throttling Libary that allows limiting the number of requests per second.
var options = Options.Create(new MarketstackOptions() { ApiToken = apiKey, MaxRequestsPerSecond = 3, Https = true });
var marketstackService = new MarketstackService(options, NullLogger<MarketstackService>.Instance);
List<string> symbols = new List<string>() { "AAPL", "MSFT", "GOOG", "VOD", "NVDA", "NFLX", "PEP", "NOW", "VEEV", "MOH" };
var fromDate = new DateTime(2017, 9, 1);
