The seven most liquid 0DTE underlyings, scored for very-short scalping. Sort by what matters to your fill quality.
Scores are relative, not absolute — a 5/5 spread means penny-wide markets you can scalp all session; a 2/5 means you pay up on entry and exit. Single-stock gamma bursts pay more but fill worse. Default to the A-graded names; reach for singles only on clean momentum.
