I would like to buy a stock of a company, unfortunately I don't have access to the stock in my local stock exchange nor do I have access to the stock exchange of the country of the company.
But I would have access to two other markets which have the stocks.
It would look like this:
(Yes, I just realized that I'm bad at drawing stuff)
From the picture you can see that I can't "access" the stock directly. Now the question is:
Which Stock Exchange should I prefer?
Both cost me the same from fees, both are same level of complexity regarding taxes. In addition, the currencies are not bound with each other (no fixed exchange rate)
