Quote from John Merchant:
Thank for ask. Merchant make up more and more elaborate fraud. But few see through. DBixon very cleaver. Little red line is Merchant proper riotary indicklater. Is where one minute volume fall below certain fraction of slow first order infinite impulse response filter on volume. Filter have proper riotary co-inefficient, of course. Merchant steal idea from Hershey. Like all Hershey idea, Merchant make actual work. Hershey use ES. Merchant use NQ. Hershey use five minute. Merchant use one. Just to be different. Hershey use absolute volume number. Merchant use adaptive threshold. Hershey call Very Dry Up. Voo-Doo for short. Merchant call his Little Red Line. Both useless. But to be ghue rhue, must have elaborate cahrt.
