gamma_flip_state

WHY gamma_flip_level is or is not there. 1: a flip was found within 25% of spot. 0: the repriced book does not cross zero within 25% - a real reading, e.g. CRSR net long everywhere nearby. -1: the model and the vendor's gamma disagree about which side of the flip spot is on, which in practice means spot is near one. NULL: no book. A CODE, NOT A STATISTIC: never rank it or read its percentile.
