The mobile kill button

2 min read · updated 2026-06-11

On mobile the kill switch is a persistent floating button that stays on screen on every authenticated page — mid-scroll, mid-form, always one tap. It never collapses into a menu; that’s a product rule, not a layout accident.

What it opens

The same three levers as desktop, with the same confirms: Pause, Cancel open orders, and Liquidate (typed confirmation included — the phrase is required on a phone keyboard too, deliberately).

Touch details

The button and the controls it opens are comfortably finger-sized for accurate tapping, and the trio is positioned clear of the tab bar so a thumb reaching for navigation never lands on a kill control by accident.
