I have always worked on the ADX has to be rising and not necessarliy it being above the + or - or for that being above 20 or 30.
The 20 and 30 levels could be seen as purely arbiturary however when it rises it is gaining momentum.
I look to see if the ADx is rising i.e. greater than the last bar before I go in on the trade.
I believe that the 20 has significance but this is more to do with the + and - lines.
I think it will be best to go with ADX rising greater than last bar and therefore creating a signal on the the next.
