Universe Growth

I'm trying tom understand why I see the universe count growing each day. Looking at the variable Securities.Count and see it incease every day even though the selection is for the top 5. Is there a way to tell wich securities are active?

You can remove the symbol in "Securities" with   

 

foreach (var security in _changes.RemovedSecurities)
{
Securities.Remove(security.Symbol);
}

When using the scheduled event method, please specify an equity symbol for the method to track the market hours

AddEquity("SPY", Resolution.Minute);
Schedule.On(DateRules.EveryDay("SPY"), TimeRules.At(09, 45), CountUniv);

I added the reference to SPY and now my algo trades SPY, not what I want. It appeard to work wthout the refering to SPY, what it the issue with not refering to a securty?

Thanks for the input.

 

I modified my code and added my own list to store the universe, then on universe change I add and remove securities. Seems to be stable at five securities as exected now.

It seems odd that the universe continues to grow when the the call is to take the top 5 each time. Is there some reason why that occurs?
