SG, after looking at the ADM/adx on the mt4 platform, I think that it may be possible to come up with something that would work on an daily chart.
Punch in 72 bars
enter 12.1 for level one
Enter 22.9 for level two
Then check the green dotted line for the recent spike bar on GU daily. Does it not indicate overbought??? Maybe whole indicator can be tweaked for better performance. But the levels I listed above could be a good starting point..
