Getting Started

Import namespaces

    using OptionEdge.API.AliceBlue.Smart;
    using OptionEdge.API.AliceBlue.Records;

Sample Class File

  public class DevTest
    {
        string? _userId = Environment.GetEnvironmentVariable("ALICE_BLUE_USER_ID");
        string? _apiKey = Environment.GetEnvironmentVariable("ALICE_BLUE_API_KEY");

        string? _password = Environment.GetEnvironmentVariable("ALICE_BLUE_PASSWORD");
        string? _yob = Environment.GetEnvironmentVariable("ALICE_BLUE_YOB");
        string? _mpin = Environment.GetEnvironmentVariable("ALICE_BLUE_MPIN");

        string _tokenFileName = "token.txt";

        AliceBlueSmart? _aliceBlueSmart;

        public void Run()
        {
            _aliceBlueSmart = new AliceBlueSmart(_userId, _apiKey, enableLogging: true,
                onAccessTokenGenerated: (token) =>
                {
                    File.WriteAllText(_tokenFileName, token);
                }, cachedAccessTokenProvider: () =>
                {
                    return File.Exists(_tokenFileName) ? File.ReadAllText(_tokenFileName) : "";                
                }
            );

            // YOUR CODE HERE
            // SEE BELOW FOR SAMPLE CODE
        }
    }

Auto login

    // Login to ANT Web 
    // set showBrowser as true to see the browser UI else false. No browser UI  will be created
    // Chromium browser needs to be installed at the binary location
    //  .\playwright.ps1 install chromium
    var isLoginSuccess = _aliceBlueSmart.Login(
        userName: _userId,
        password: _password,
        yob: _yob,
        mpin: _mpin,
        showBrowser: true).Result;

    if (isLoginSuccess)
        Console.WriteLine("Logged in to ANT Web successfully.");
    else
    {
        Console.WriteLine("login to ANT Web failed.");
    }

Create Ticker and subscribe for live feeds

    // Create Ticker for live feeds
    var ticker = _aliceBlueSmart.CreateTicker();
    ticker.OnClose += ticker_OnClose;
    ticker.OnConnect += ticker_OnConnect;
    ticker.OnTick += ticker_OnTick;
    ticker.OnReady += ticker_OnReady;

    // Subscribe for live feeds by instrument token 
    ticker.Subscribe(Constants.EXCHANGE_NFO, Constants.TICK_MODE_QUOTE, new int[] { 2222 });

    // UnSubscribe from live feeds
    ticker.UnSubscribe(Constants.EXCHANGE_NFO, new int[] { 2222 });

Search Contracts by Symbol or Token

    // Load all contracts for NFO in memory
    _aliceBlueSmart.LoadContracts(Constants.EXCHANGE_NFO);

    // get contract by instrument token. 
    var contract1 = _aliceBlueSmart.GetInstrument(Constants.EXCHANGE_NFO, 51942);

    // get contract by trading symbol
    var contract2 = _aliceBlueSmart.GetInstrument(Constants.EXCHANGE_NFO, "symbol");

Get LTP (Last Traded Price)

    // Get Last Traded Price by Trading Symbol or Instrument Token
    var ltp = _aliceBlueSmart.GetLTP(Constants.EXCHANGE_NFO, "BANKNIFTY22SEP40800CE");

Expiry Calculator

    var expiryCalculator = _aliceBlueSmart.CreateExpiryCalculator(DateTime.Now);

    var allExpiries = expiryCalculator.GetExpiries();
    var monthlies = expiryCalculator.GetMonthlies();

Expiry Calculator Output

    15-09-2022
    22-09-2022
    29-09-2022
    27-10-2022
    24-11-2022

Symbol Generator

    // Get NIFTY current week's PUT ATM strike symbol
    var niftyCurrentWeekATMPut = symbolGenerator.GetSymbol(
        "NIFTY", 
        allExpiries[0], 
        ALICE_BLUE_API_OPTION_TYPE.PE, 
        symbolGenerator.GetATMStrike(17343, 50));

    // Get BANKNIFTY next week's Call ATM strike symbol
    var bankniftyNextWeekATMCall = symbolGenerator.GetSymbol(
        "BANKNIFTY",
        allExpiries[1],
        ALICE_BLUE_API_OPTION_TYPE.CE,
        symbolGenerator.GetATMStrike(39856, 100));

    Console.WriteLine(niftyCurrentWeekATMPut);
    Console.WriteLine(bankniftyNextWeekATMCall);

Above code generates NIFTY2291517350PE & BANKNIFTY2292239900CE symbols.
