I have been toying with the idea of having 2 setups which in one you risk 1% and on the second you risk 2%. Obviously the second would need to be more probable in order to withstand a larger risk but also a bigger reward.
Any thoughts?
My thoughts:
If I have a setup that required a tight SL then I will risk less 0.5-1% because of the higher R:R ,a wide SL 1-2%, so I don’t see anything wrong with this. Some will tell you to always risk the same amount on every trade, but whatever works.
I would like to think that ALL your trades are high probability 
…or a bigger loss. Always look at how much you could lose first, not how much you could gain.
Tell us a bit about what you’re thinking.
Different risk for a different strategfy is perfectly rational - as long as you take into account the win rate.
It is the best way to compound an account. However, I think you also need to create a buffer.
