Shortable universe

Hey OvidiuS 

After adding your stocks trough the universe you can call this method:

is_shortable_quantity = self.Shortable(symbol, quantity)

Read more here: 

Sry didn’t saw the programming language. Here’s the same code but with C#:

var isShortableQuantity = Shortable(symbol, quantity);

Thanks for links and example, I'll give it a try

I just wanted to share my solution if anybody needs it in the future.

	private void SetupAlgoBrokerage()
	{
		SetBrokerageModel(new InteractiveBrokersBrokerageModelWithShortable(AccountType.Margin));
	}
	    

	private void SetupAlgoUniverse()
	{
		// Add stocks
		AddUniverse(CoarseFilterFunction, FineFundamentalFilterFunction);
	}


	IEnumerable<Symbol> CoarseFilterFunction(IEnumerable<CoarseFundamental> coarse)
 	{
		return coarse.Where(c => c.HasFundamentalData).Select(c => c.Symbol);
	}


	public IEnumerable<Symbol> FineFundamentalFilterFunction(IEnumerable<FineFundamental> fine)
	{
		return fine.Where(f => f.MarketCap < 1000000000 && ShortableQuantity(f.Symbol) < 500000).Select(f => f.Symbol);
	}
        
        
	public class InteractiveBrokersBrokerageModelWithShortable : InteractiveBrokersBrokerageModel
	{
		public InteractiveBrokersBrokerageModelWithShortable(AccountType type) : base(type)
		{
			ShortableProvider = new AtreyuShortableProvider(SecurityType.Equity, Market.USA);
		}
	}
