Getting Started

Console App:

/* Get Code */
//This will open up Chrome browser -- login in your TD account
// You will be redirected to your redirectUri with the code
TDAuth.GetAuthCode(clientId, redirectUri);

/* Get AccessToken */
var accessToken = TDAuth.GetAccessToken(clientId, code, redirectUri).access_token;
var client = new TDClient(accessToken, clientId);

/* Get Historical Chart Data for ROKU */
var priceHistory = new PriceHistorySettings
{
      symbol = "ROKU",
      periodType = PeriodType.Month,
      period = 6,
      frequencyType = FrequencyType.Daily,
      frequency = 1,
      needExtendedHoursData = true
};
var historicalData = client.GetPriceHistory(priceHistory).Result.Data;

/*Streamer */
var streamer = new TDStreamer(userPrincipals);

//Streamer currently has 2 request examples: login and timesales in TDClient.cs. 
See https://developer.tdameritrade.com/content/streaming-data for more endpoints.

//Create a streamer request example
 var _TIMESALE_FUTURES = new StreamerSettings.Request
            {
                service = "TIMESALE_FUTURES",
                command = "SUBS",
                requestid = "1",
                account = userPrincipals.accounts[0].accountId,
                source = userPrincipals.streamerInfo.appId,
                parameters = new StreamerSettings.Parameters
                {
                    keys = "/ES,/CL",
                    fields = "0,1,2,3,4"
                }
            };
