What is the minimum required investment?

To make 100K a year you need to invest around $25,000. But if you have less than that e.g. $10,000 then that's ok as well. What you will need to do is to first work your way towards the $25,000 goal. Once you get there you will be able to make $500 a day from trading. All this can happen as long as you follow the method, follow risk management rules and apply the minimal work required. (i.e. 1-2 hrs a day max).
