ema-sma
oscillator from the difference between Ema and Sma, moving around 0 line, Quite reactive if use the cross of the 2 lines , more conservative if wait the lines cross the zero line. I add columns for the big change of volume with the cut off so it s show only big divergence with the avarage. colors show trends. I think usefull
