My thread of how not to blow up draw some attention. Now I want to discuss risk reward ratio. My assumption is that you have no edge in trading and every trade you enter has 50% chance of win. The intuition tells me by setting up wrong r:r would ruin your chance of win. obviously if your r:r is 1:2 and you still get 50% chance , u will make money for sure. it is very obvious your winning odds is less than 50% if your r:r is 1:2. there is something deeper here, how to set up r:r according to price volatility is something can be done here. So even you have no edge at all, but doing some math (analyzing volatility), you probably slightly increases the winning odds. I just don't know how to do it yet.
