As mentioned previously, Armstrongs calls are at times too flexible and infrequent to trade accurately. Although the Dow did only touch the Weekly reversal, the other high of last week made things ambiguous, as well as the Friday/Tuesday high. So many makes it unusable. He wasn't wrong about the Weekly Reversal and mentioned that a close above would constitute a wrong call.
Also, I do better with my own system. Will probably just do that instead. Heck, maybe I should make my own service. Clear cut and works most of the time, with multiple calls daily.
