Bago: Try a period 15 setting for the 30 min. ADX. You will see that it blends nicely with your indicators and with Wattah entry signals. I knew someone who used only a 15 ADX to make all his trading decisions, and he did well, with entry at the time the ADX line pentrates between the D+/D- bands, the most desirable penetration from below or from the side, but occasionally working nicely with penetration into the zone from above. My current bago setup includes them all.
