Following WTI OIL downtrend failure last Friday, USDRUB tagging its relevant uptrend border first time since it started its descend back in July, marked by lower 1st standard deviation from quarterly (66-day) mean (@65).
If the price manages to break below the border, chances are the uptrend is over (or at least current leg of it).
Full stop of the uptrend, however, can only be declared when the price trades above the quarterly mean (@59).
