The USD/CHF is holding on strength as seen in the 4H chart above. The 55 period simple moving average in red has acted as support since it was crossed in the beginning of November, and tested as support. A sling shot followed, and it is still acting as support at the end of November, pushing back a a strong attempt to break it in the 11/29 European session. (That attempt gave us the 3rd to last candle here, with a long tail to the bottom and barely any body - a sign of an indecisive bearish attempt).
The RSI has been tagging 70 - a sign of bullish momentum, and staying above 40, a reflection of the maintenance and persistence of bullish momentum. Also an occurrence since kissing 70 to begin November.
This strength looks to be weakening, or flattening as the slope of the 55-SMA eases. A bearish breakout will be indicated by a slide below 0.9150, a pivot established Nov 10 as resistance. It is also reinforced by the 23.6% retracement.
