please , any good regulated broker from spain , if you know one or two and you have traded with them either currently or in the past can you let us know your experienced with them, also will like to know if they have a physical office where we can verify them and ask some questions.
Guess your searches are doomed to fail cuz its a suicide for forex broker to register in spain with very high financial tax burden.
I can suggest you to follow my choice, it’s CySec regulated broker Hotforex, guess you’re able to trade with them as they have MiFid passport and accept EU citizens.
Start with demo first! And have a look into babypips pip school to get a clue what to start from.
