The same principle is used here as in Trend direction && force index_(finger trap_4)_m092 (JMA inpPeriod_bs_ft is bound). But since there are two periods in the JMA z - score, two coefficients are used (coefficient_ft, coefficientZs_ft). You can not include them (inpPeriod_ft, inpPeriodZs_ft), then you will get a regular JMA z - score.

Green. JMA z - score ft.
