=AND(E144 less than E143,E143 less than E142,E145 greater than (B145+(MAX(C142:C144)-MIN(D142:D144))/2)) E= TNA CLOSE, C= TNA HIGH, B= TNA OPEN, D= TNA LOW; BUY EASIER DAYS occurred on 145 (2/23/2012), 142 (2/16/2012), 130 (2/1/2012), 120 (1/18/2012), 95 (12/9/2011), 48 (10/4/11) & 19 (8/23/2011).

146 (today) & 96 (12/12/11) GRIDS match well suggesting a down day on Monday.
