Wait-both-sides flips after GE tax. Ranked by expected gp per 4-hour buy-limit window — not margin × limit.

Any two-sided book with a positive after-tax edge.

Cash stack

Edge = insta-buy − insta-sell − 2% tax (0% on bonds and other tax-exempt items). expected_gp_4h = after_tax_edge × min(buy_limit, cash/insta_sell, 0.4 × daily/6). Thin / stale / wide tags are warnings, not hides.
