Why do you have to equate high gain with high risk?
Why not aim for low risk, high gain?
Well the general equation of Mathematic law already stated : Gain = System(Y) * Risk
System(Y) will be a wave of up and down which sometimes you win and sometimes you lose, an oscillator graph.
So we normally adjust the Risk parameter will result High risk produce high gain.
To get High Gain Low Risk you certainly need a System(Y) which probably manual is the best. Which is the core logic key direct factor to Risk, as already someone give an example that some trader can 2k earn 20k in a month and 20k earn 250k a year yet fail due to Risk MM control.
So what kind of common System(Y) you think of :
Probability factor of Low gain low risk System(Y) : +1, +0.2 ,+0.5, +0.7, +0.3, +1.1, -2, -0.1, -0.5, +0.5,
Probability factor of High gain high risk System(Y) : +2, -1, +1, +0.6 , -3, +1.5, +0.5, +4, -1, +2,
