Scan NASDAQ

This is possible with universe selection - check out the documentation for more examples.

Whether a stock is in the NASDAQ is proprietary data which we do not have (and is very expensive). So to do NASDAQ exchange filtering you'll need to provide this data yourself and use it as a custom universe.

I'm fairly proficient in programming c# however I can't quite make sense of the syntax used in the online platform.  I can't find where I can implement intricate logic to test some ideas I have (i.e. scan for stocks that experience a drast rate of change in volume and if other criteria are present enter a trade, etc.).  Is there a more rudamentary step by step guide to getting started?

Hey Jim, 

I am actually working on a strategy right now that requires the use of filtering through the whole universe of stocks. What my strategy aims to do is first create a list of the top 100 stocks by dollar volume, and then sort by the top 10 stocks with the greatest positive price change, and the top 10 stocks with the greatest negative price change. While the strategy itself isn't profitable, it does show some further uses that the Universe selection is capable of.

Bryan,

I would love to take a look at your strategy.  I'm very interested in some of the key points of strategy as it's very similar to what I'm looking to produce.  I'm also very curious to see if this can be applied in realtime and if I can see or filter on volume data to the minute as my strategy heavily relies on identifying a drastic change in the volume rate of change.  I'm assuming the QuantConnect platform will allow for this kind of analysis/filtering but I'm unsure.  I'm currently parsing through algorithms but I've yet to find any with remnants of what I'm looking for.  I would be satisfied with a strategy that works on realtime data and that sees volume to the minute.  I'm confident I can take it from there.
