The answer to this question depends on the following variables:

- Win size (
**W**)
- Loss size (
**L**)
- Winning rate (
**P**)

Or, put differently, it depends on the probability-adjusted size of profit vs. a probability-adjusted size of a loss.

What we all want is to maximize our Expectancy (

**E**):

E = W × P - L × (1 - P)

The effect of doubling the profit is equal to that of halving the loss when:

2 × W × P - L × (1 - P) = W × P - 0.5 × L × (1 - P)

W × P = 0.5 × L × (1 - P)

I.e., it makes sense to double the profit vs. halving the loss when the probability-adjusted profit is at least half the probability-adjusted loss.

For my strategy, considering that the probability-adjusted profit is almost 3 times the probability-adjusted loss, I would definitely prefer to double my profit.
