Risk reward does not mean simply calculating the risk and reward on a trade, it means understanding that by achieving 2 to 3 times risk or more on all your winning trades, you should be able to make money over a series of trades even if you lose the majority of the time. The fixed $ risk was set at $100 per trade in this example just to show how a trader who is confident in his or her trading skills and trades like a sniper would be able to build his or her account faster than someone settling on a 2% per trade risk.
