gamma_flip_distance_atr
Where net GEX changes sign, as LEVEL MINUS SPOT in 14-session ATRs. NEGATIVE means spot is above the flip, on the side the sign convention calls positive gamma. Found by repricing the book at hypothetical spots (sticky strike, r = 0); NULL when no flip lies within 25% of spot.
