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.
