Hello,
I'm having an issue with usnig a foreach loop inside my array declaration for my manual universe selection. This little issue is tripping me up quite a bit in moving forward, so any help would be really great!!!
//Tickers
string[] arrayofTickers = new string[] {
"EIDX",
"MGTA",
"AVRO"
};
public override void Initialize()
{
//General housekeeping and setup
SetStartDate(2018, 1, 15); //Set Start Date
SetEndDate(2018, 7, 15); //Set End Date
SetCash(100000); //Set Strategy Cash
UniverseSettings.Resolution = Resolution.Minute;
maxMinCount = maxDayCount*1440;
//Save number of tickers to a global int for later loop purposes in onData
numTickers = arrayofTickers.Length;
var symbols = new[] //Building list of all tickers for the universe
{
//foreach loop here? for QuantConnect.Symbol.Create(arrayofTickers[i], SecurityType.Equity, Market.USA)
};
//Set universe mode selection to manual
SetUniverseSelection(new ManualUniverseSelectionModel(symbols));
//Set all other modules to null
SetAlpha(new NullAlphaModel());
SetPortfolioConstruction(new NullPortfolioConstructionModel());
SetExecution(new NullExecutionModel());
SetRiskManagement(new NullRiskManagementModel());
}

New to QC, but this is typically what that would look like for me (unless you are into LINQ).
// At top of file, to support List<> using System.Collections.Generic; // Create a list of Symbols List<Symbol> symbols = new List<Symbol>(); foreach (var ticker in arrayofTickers) { var symbol = QuantConnect.Symbol.Create(ticker, SecurityType.Equity, Market.USA); symbols.Add(symbol); }Scott Senkeresty
I actually suspect I'm telling you to do things sorta outside the norm of QC :) It would not surprise me if 1 or both of us over complicated things, in that I don't know the difference (yet) between a Symbol and a Security. I could imagine this would be fine...
foreach (var ticker in arrayofTickers) { Â Â AddEquity(ticker, Resolution.Daily); }And just use the Securities dictionary to retrieve them as necessary. But I don't know things :)
