Cross-Venue Trading and Stock Listing Data

Summary

The discussion distinguishes a stock’s listing venue from the places where its trades can execute. In US cash equity markets, a stock listed on one exchange may also trade through other exchanges, electronic communication networks, or dark pools. As a result, finding a second listing is not necessarily the same as finding other venues that handle the stock’s trades. Actual execution on a venue is a separate question from eligibility to trade there.

For research requiring data from multiple venues, the thread suggests that venue-level activity should be checked rather than inferred from the primary listing alone. It also mentions a data service as a possible source for identifying cross-listed securities. The answers do not provide a systematic screening procedure, volume thresholds, or a method for verifying current venue activity. The question’s requirement for high average trade volume therefore remains unresolved, and venue coverage depends on the available market data.

Key ideas

• A stock’s primary listing does not determine every venue where its trades may execute.
• US cash equities can trade across exchanges, electronic communication networks, and dark pools.
• Eligibility to trade on a venue does not establish that the stock actually executes there.
• Multi-venue research needs venue-level data, and the thread does not supply a screening method or volume test.

# Finding a stock traded at two venues












For a project of mine I need to find a stock that is traded on two venues, e.g. `NYSE` and `NASDAQ`, but could be others.

So I need to use data from both venues.

Does anyone know how one would go about finding a stock that are traded on two venues?

Because it seems like an overly tedious task to go through the single stocks one by one and check if they are on another exchange. Are there e.g. a list somewhere with this information?

Another information that is important in my choice is, that it needs to have a very large average trade volume.

I'm not sure the question makes sense with today's cash equity markets. Pretty much all cash equities can trade on any of the 40 dark pools and ECN's in the US.

See: https://en.wikipedia.org/wiki/List_of_stock_exchanges_in_the_Americas

So, I guess the answer is that almost all stocks listed on say the NYSE can trade on any of the other stock exchanges. Now whether or not they actually execute trades on those exchanges is another story.
