Thanks for your response. Unfortunately, many stock and ETF brokers have an annual swap of around 7-8%, which, in my opinion, is immensely high. These investments would only be suitable for short-term trading systems.

Unfortunately, I cannot find a decent broker that easily connects with Zorro and instead of swap fees, simply charges a one-time order fee.

The forum has a good broker recommendation.
I continue searching for an ETF/stock broker with API integration and write the script myself.

Thank you!
