I think I found the formula for Metastock for this oscillator but the signal line is missing. I am assuming the signal line is some kind of moving average of an unknown period. Does anybody have the parameters for the signal line? Thanks . . . . . . . Here's the formula for metastock: (Mov(Mov(C-O,5,E),26,E)/Mov(Mov(H-L,5,E),26,E))*100
