USD/CHF Technical Analysis: Greenback losing some steam below 0.9950 level

• USD/CHF is in a bull trend as the bulls broke above the 100-day simple moving average (DMA) on the daily time-frame (not shown). 
• USD/CHF is finding some resistance and is having trouble to move beyond 0.9950 as the week is about to come to an end. The pair has been on a strong bull run with the RSI and Stochastics indicators being in overbought conditions for more than a week. The MACD crossover is also suggesting that a small pullback can be on the cards for USD/CHF. 
• The 0.9891 level (October 4 low) and 0.9868 (July 31 low) should act as levels of support on a pullback.
