A risk/reward ratio is the measure of profit you intend to jump on a position with respect to what you are risking in the event of a loss. Basically, if your Stop Loss equivalents to 10 pips and your Take Profit is 50, your risk/reward ratio is 1:5. Risk/reward proportion is something else you can control. So as to build your odds of getting a profit, it's prescribed to consistently have a greater reward than risk.
