The truth is that all these depends on you as an individual and your style of trading which basically sums up with what you are comfortable with. If you want to day trade and you can cope, then you can manage to be hitting your 1 - 2% daily, but you should know that market is not a rosy thing you will just assume a  consistent 1 - 2% daily or 20-30% monthly, most especially when it is in a bear trend. However, the main thing is to be sure you have what it takes to trade with a strategy and a plan, not just gambling your position.
