Is there a way to just pass an array into the manual universe section?
Start New Discussion 
Backpublic override void Initialize()
{
UniverseSettings.Resolution = Resolution.Minute;
var symbols = new [] { QuantConnect.Symbol.Create("SPY", SecurityType.Equity, Market.USA) };
SetUniverseSelection( new ManualUniverseSelectionModel(symbols) );
}so instead of "SPY" say I have 10 tickers sitting in a string array. How can I dump those guys in there easily without having to repear t whole line 10 times?

The reason for the line
QuantConnect.Symbol.Create("SPY", SecurityType.Equity, Market.USA)
is because the ManualSelectionModel takes in an array of type Symbol. The Symbol objects are initialized in this line using their ticker symbol. Since repeating the line can be tedious a for loop can easily be made that creates the object and adds it to the array:
string[] symbol_set = ["PFE","IBM","SPY"]
foreach(string s in symbol_set){
symbols.push(QuantConnect.Symbol.Create(s,SecurityType.Equity,Market.USA))
}Excellent, thank you!!
Actually, that for loop is giving me an error still :-/ I had tried a simple for loop before. Error I have seems to be comma or bracket based... am I missing one here?
string[] arrayofTickers = new string[] {
"SPY",
"GOOG",
"TSLA"
};
var symbols = new[]
{
foreach(string s in arrayofTickers){
symbols.push(QuantConnect.Symbol.Create(s,SecurityType.Equity,Market.USA))
}
