How can I set the dmi + and dmi - line to 28. Is that the Average Period ?

The +DI Line and -DI Line are calculated using only the DX Period (so this is what you probably wish to change to 28). The ADX Line combines the +DI and -DI Lines and applies Wilder's Smoothing using the Average Period.

I appreciate your answer, but I don't understand what I need to do on Telechart. I want my Adx Line to be 12, and the dmi + dmi - to be 28. How do I configure that into Telechart.

Thanks

The following is a basic list of the steps to calculate ADX (these aren't Personal Criteria Formulas):

y = DX Period
z = Avg Period
TR = MAX(H-L,H-C1,C1-L)
ATRy = (Yesterday_ATRy*(y-1)+TR)/y
+DM = IF H>H1 AND H-H1>L1-L THEN H-H1 ELSE 0
-DM = IF L1>L AND L1-L>H-H1 THEN L1-L ELSE 0
+DMIy = (Yesterday_+DMIy*(y-1)+(+DM))/y
-DMIy = (Yesterday_-DMIy*(y-1)+(-DM))/y
+DIy = 100*(+DMIy)/ATRy
-DIy = 100*(-DMIy)/ATRy
DXy = 100*ABS((+DIy)-(-DIy))/((+DIy)+(-DIy))
ADXyz = (Yesterday_ADXyz*(z-1)+DXy)/z

You may alternately calculate ATRy, +DMIy, -DMIy and ADXyz as follows:

ATRy = XAVG(TR,(2*y-1))
+DMIy = XAVG(+DM,(2*y-1))
-DMIy = XAVG(-DM,(2*y-1))
ADXyz = XAVG(DXy,(2*z-1))

TeleChart displays the results of the calculations at only three of these steps:

+DIy
-DIy
ADXyz

The values for +DMIy and -DMIy are not displayed but their calculation involves only the DX Period (so my guess at the meaning of your question would suggest the DX Period should probably be 28 as indicated in my previous response). The calculation of ADXyz involves both the DX Period and the Avg Period (so my guess at the meaning of your question would suggest the Avg Period should probably be 12, but realize it will use the DX Period in its calculations as well).
