Try other models and your own priorities
Presets are starting points. Swap either side, then open Advanced weights only if you want to tune the formula directly.
09 · Alternative
A third option worth checking
The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.
No cleaner third option in this dataset
The scenario-aware check did not find a currently priced alternative that improves this decision without changing the trade-off. This is a dataset result, not a claim that no other product exists.
