I'm creating a realtime stock quotes application that uses the IEX API (https://iextrading.com/developer/docs/) to get real time infomration. I'm wondering if there is a better way to poll this URL than what I currently have.

string Symbols = "AAPL", "AMD" ;

var Url = string.Format("https://api.iextrading.com/1.0/stock/market/batch?symbols=0&types=quote", string.Join(",", Symbols));

 using (var client = new HttpClient())
 
 while (true)
 
 using (var request = new HttpRequestMessage(HttpMethod.Get, Url))
 

 using (var response = await client.SendAsync(request))
 
 var stream = await response.Content.ReadAsStringAsync();

 if (response.IsSuccessStatusCode)
 
 var r = JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, Quote>>>(stream);
 Console.WriteLine(JsonConvert.SerializeObject(r[Symbols[0]]["quote"].latestPrice));

 
 
 
 
 

What I currently have works fine, I'm just wondering if there is a better/more effecient way to do this.

You might want to see if they have a live quote feed you can just subscribe to and watch.

It's astonishingly inefficient to keep asking for quotes for specific stocks when you don't know if anything has actually changed.

You'll be asking when nothing has changed and delaying unnecessarily when things have changed.
