How do the charts look today?
In the updated daily bar chart of NOW, below, we can see that the shares reached the $680 level before pulling back. NOW has been testing the rising 50-day moving average line. The 200-day moving average line intersects down around $550 so NOW would not be considered extended or overbought versus the 200-day line.
The daily On-Balance-Volume (OBV) line has been strong since early June and confirmed and supports the price gains we have seen. The Moving Average Convergence Divergence (MACD) oscillator turned lower in early September and is now close to crossing below the zero line.
