Daily fees when swing trading

Hi there, I recently opened a demo account with a platform called plus500, I then opened a position on Friday. Plus500 charges a calculated fee daily on every open position, it has been 3 days now that the position has been opened and my fee sits at 10% of my initial investment. Is this a normal fee or a platform specific one? How do other swing traders cope with keeping positions open if there is a fee against doing that?

Thanks for any assistance

It was my understanding that, due to differences in interest rates offered by the various central banks, it was actually possible to get paid a small amount for taking a long position and keeping it open.
