QUANTCONNECT COMMUNITY
Hello Everyone,
I want to do either
1. Run universe selection on the same day where the algorithm will be called "not the previous day" -> Get the Top Gainers and run my algorithm minute by minute on those Top Gainers
2. Run universe selection continuously during the day, "with onData" so I can detect stocks that are raising during the trading session "Similar to what you can do with InteractiveBrokers MarketScanner API"?
Are any of those two options doable with QuantConnect?

Hi Emma R ,
It is not possible to run universe selection "continuously" because we don't take "market snapshots" with that frequency, for instance, Coarse Universe is a built-in universe (market snapshot) that is generated only once per day after the market is closed.
If the objective is to detect stock that are rising, we can simply subscribe to a large universe and keep track of prices changes in OnData (or any other method, since the information can be found in Securities object).
