Swissquote
I'd also be interested to hear from anyone who has used Swissquote as a trading platform - specifically ETFs.
I compared Swissquote.ch and Swissquote.ae and saw that the former is significantly cheaper for ETFs, although you would not have the Dirham (AED) sub account option in the current account.
The Swiss site charges €9 for buying and selling ETFs and an annual maintenance fee of 0.1%. The UAE site charges 0.25% buy/sell fee and 0.15% annual maintenance. This is a significant difference!
If you went with the Swissquote.ch option, you would have to deal with them directly and not be able to use the local Dubai office for account opening, advice etc. but do you really need to?
