Interest..every thing about it plz

Hi I am a newb and looking for your help about interest.
Do you pay interest when making a trade? Do you receive interest in a point of time?
Can I get around it like maybe pay a fixed price or commission? Or dose each broker have a way that he will not change or negotiate. My questions may sound dumb but I am new to this, I use fxpro by the way

Thnx in advance

These are questions you can easily find the answer to yourself with just a bit of research.

Have you gone through Babypips school?

Google, read and learn about ECN versus market maker and check what SWAP and rollover is and you’ll soon have your answers.

Investopedia is a good site to check out for learning when you’re done with BP school.
