Usually you can extract information/data like this from financial data vendors (Bloomberg, Reuters, etc.). I am going to explain how you can get volumes of a stock traded on different exchanges using Bloomberg:
- Type in the search box AAPL
- Hit
- Type in VWAP
Then you can play around with different parameters like period
, price
, volume
, etc. Under the column Breakdown
you have the names of the exchanges where the security is traded and respective volume under the column Volume
.
You can also check the exchanges on OpenFIGI. Just refine the filter by selecting Common Stock
in Security Type
. Unfortunately, this page only gives the Exchange codes. Here is a link to an excel file where you can find the full details of Exchanges by their code.
Let me know if you have any further questions.
