we can produce as much as we can but with the right plan, a little mistake can make you lose your money. it depends on you how you plan to invest and how you trade. The more risk we expose our capital to the more benefits we can expect but to provide the right protection of our capital and use risk management steps I think 1-2% of profit in a day can be expected. I think forex is a good job. 1 to 2 daily earnings is a very reasonable and easily achievable target with minimal risk. the amount of profit may increase as well if the trader is prepared to take a higher risk. but it's always safe to take the minimum risks and make a reasonable profit rather than take more risks to earn more. so it depends on the merchant itself to generate little or more profits based on his trades.
