Здравствуйте. S# 5.0 и Quik 8, Windows 10 Pro, WS 2019, .NET 4.8 FW. Пытаюсь получить значение маркет-данных для инструмента: private Security testSecurity; private string isin = \"RU000A0JU286\"; private void Test_Click(object sender, RoutedEventArgs e) { foreach (var sec in connector.Securities) { if (sec.Code == isin \u0026\u0026 sec.Board == ExchangeBoard.MicexEqob \u0026\u0026 sec.Currency == CurrencyTypes.RUB) { connector.SubscribeLevel1(sec); testSecurity = sec; } } Trace.TraceInformation($\"\u003e testSecurity {testSecurity.Code} / значение {connector.GetSecurityValue(testSecurity, Level1Fields.PriceStep)}\"); Trace.TraceInformation($\"\u003e testSecurity {testSecurity.Code} / значение {connector.GetSecurityValue(testSecurity, Level1Fields.BestBid)}\"); } Результат null, что не так?
