Prices are in US dollars per share. Net GEX is modeled dollar-delta change per $1 underlying move. Max pain minimizes aggregate intrinsic payout for that expiration; it is not a closing-price forecast. Signed GEX uses calls positive and puts negative, a model convention rather than observed dealer inventory. The flip is a confirmed zero crossing; walls locate side-specific concentrations, not guaranteed support or resistance.

Returns are close-to-close after the labelled number of subsequent trading sessions. The confidence floor is the closest-to-zero bound of the order-statistic median interval; it is zero when that interval spans zero. Its coverage is nominally at least 90% under independent observations. Historical paths can overlap, so the interval and floor are descriptive uncertainty guides rather than formal coverage guarantees. Historical, not a forecast.
