Hi, I tried to figure out why below AFL code doen't give me the same results. The value calculated using REF and ROC are different.
AddColumn(C-Ref(C,-5)/Ref(C,-5)*100, "ROC -5 using ref", format=1.3); AddColumn(ROC(C,5,False), "ROC 5 using ROC false", format=1.3); AddColumn(ROC(C,5,True), "ROC 5 using ROC true", format=1.3); But the AFL manual says that if absmode = False the value returned is ( array - ref( array, -periods ) )/ref( array, -periods ) if absmode = True the value returned is ( array - ref( array, -periods ) )/abs( ref( array, -periods ) ) Another question is what is the difference in results between ROC(C,5,True) and ROC(C,-5,True) Thank you, Radek
