I am looking for open data about daily whole stock exchange volumes in order to test the claim that Amsterdam ousted London as Europe’s top share trading hub by the Financial Times. I didn't find the volume information on yahoo finance ...
Here's another secondary source of the info:
It turns out the calculation was made by "Cboe Global Markets", who will have real-time market data access ($$$).
I tried to recreate the numbers but for the London exchange I only found
where the daily trading amount is on average ~£4 billion (see excel download for more days).
I couldn't find any recent data for the Amsterdam exchange.
So without reading the actual report from Cboe, it's hard to know where they are getting their numbers.
