I think no one can give you the right answer about your query because, it depends on your skills and experience that how much you take risk and how much you do technical analysis. but, in my trading experience I want to say that doing trade and make continuously profit on daily basis is not possible. Because, Forex trading is very risky business where we have need to also bear the loss sometime. A trader always have need to think like a professional trader who believe on consistency and do trade with proper technical analysis and proper money management. The type of traders always make consistent profit from the market.
