Z-transform data, data after normalization
$$\right{ \begin{array}{cc} data > 1.5 = & 1 \ data < -1.5 = & -1, \ otherwise, = & 0\end{array}$$

Steps to transform the data:

normalize the data (subtract off the mean, divide by the variance)
Calculate Z-score (if z < -1.5, data = -1, -1.5 <= z <= 1.5 data = 0, z >= 1.5 data = 1
run discrete conditional independence test (y0 also dagitty)
