Good day
In fact, the big Swiss banks are very expensive when it comes to trading for private individuals. There are much cheaper trading platforms from Swiss banks. You will find all relevant banks listed in the trading comparison on moneyland.ch.
Important: moneyland.ch is a Swiss comparison service. In the trading comparison tool on moneyland.ch only providers with a full Swiss banking license are listed. Interactive Brokers is therefore not listed.
In general: No objections to Interactive Brokers and several other international trading providers. Often these are even significantly cheaper than the cheapest Swiss banks. However, we only recommend international brokers to people who trade often and are already well versed in trading.
Reason: Unfortunately there are many dubious international providers in the field of trading (Interactive Brokers is not one of them). In addition, the price differences between "cheapest" Swiss providers and international providers are not huge for those who trade infrequently.
However, alternative international platforms such as Interactive Brokers can be worthwhile for frequent traders.
