If my take-profits are 2x what my stop-loss is...
Then it is 2x as likely to hit the stop-loss first.
Thus, it breaks even.
That's how I see it.
I see it this way.
But you can get an edge.
A tiny difference that make it profitable.
If you have no edge and 1Risk / 1Reward,
The odds are 50/50 but you can make it 45/55.
Then you bet % according to kelly criterion.
You adjust your risk dynamically.
However costs can kill any apriori edge.
