5% monthly is completely unrealistic, regardless of market.
Novices need to learn how to invest long term before even thinking about short term trading.
Most "traders" lose money...
Most investors average an 8-12% annual return over the long run (although over the last five years, 20% a year has not been unusual...)
Is 5-10% ROI a month a realistic amount if you're a trader? Can it be sustained throughout the year with 5% minimum?
Does it differ from one market to another? For example I invest/trade in Bursa Malaysia, will it give me better returns against say the Indonesian market?
