I have learnt not to argue about the way people run their own things. We all know that Demo account is just the best way to introduce one to practical trading. I have also heard a couple of traders say they prefer to trade in cents, not that they don't use Demo but that they want that feeling of investing and subsequently becoming serious. The most important thing is, if you discover a strategy that works for you, adopt it.
Not actually how people want or will run their thing. Forex trading to me have just on way to do it so when you are not following that step and trying to introduce your own, you will be going on the wrong directions. T demo account is a pre requisite to being successful in forex trading and that should be known.
