Keep the auto fee, pick a preset or set a custom one. The fee is how you win routed volume or premium-price scarce pairs.
Every position carries its own fee. The builder pre-fills one for the pair.
Presets cover common tiers. Custom lets you set the exact fee you want.
Lower fees win routed volume. Scarce pairs can carry a premium.
Extreme custom fees get an explicit warning before review.
This flow is automatically verified on every release.
