      "quote": "Uses tiny tick probes, a sub-tick probability filter, and marginal retail-versus-arbitrage sizing to quote one tick inside the competitor. Starting from the exactly reproduced base, adds demand-matched crossing cover at ticks 2-9. When estimated probability is between 2c and 10c and YES inventory is below the desired ordinary ask quantity, a bid rests at floor(100*p), sized to the inventory shortfall, capped by 30% of cash-plus-YES marked wealth"

Require 0.3 ticks of estimated margin for ordinary bids and asks (dmin, formerly 0); lower the probability floor below tick one from 0.0005 to 0.000001 (pfl). The margin filter removes thin-edge ordinary quotes while preserving the separate tick-one stock bid; the lower probability floor permits more retail quoting in deeply NO-valued states. Retain the original inventory-purchase and queue rules. Each"

On spread-4 both sides, replaces the fixed two-share minimum for retaining a front-of-competitor queue position with a $2 threshold divided"
