Silly questions about rollover.

Hi guys,
>>
I cruise through posts in this forum and found out that some people receive/pay rollover charges (see the attached picture). I surf the web and got the definition of rollover but still don’t quite understand. My broker never had rollover charges whatsoever. I don’t even have the Rollover word on my platform. Why some brokers have this charge and some don’t? If my broker were to provide rollover, would it mean I could decide when to settle the trade? Who really decide the settlement date? Would it consider an advantage or disadvantage to have this rollover? So confuse :-(

Rollover

For positions open at 5pm EST, there is a daily rollover interest rate that a trader either pays or earns, depending on your established margin and position in the market. If you do not want to earn or pay interest on your positions, simply make sure it is closed at 5pm EST, the established end of the market day. Since every currency trade involves borrowing one currency to buy another, interest rollover charges are an inherent part of FX trading. Interest is paid on the currency that is borrowed, and earned on the one that is purchased. If a client is buying a currency with a higher interest rate than the one he/she is borrowing, the net differential will be positive – and the client will earn funds as a result.
