问题如下：
If the 5-day moving average for AZB Company crossed over its 60-day moving average from underneath, it would be considered a:
选项：
A.bullish indicator.
bearish indicator.
new level of resistance.
解释：
A is correct.
When the short-term moving average crosses above the long-term moving average, it can be viewed as a bullish buy signal. For example, a 5-day short-term moving average (a proxy for short-term momentum) breaking up through a 60-day longer-term moving average (an indicator of intermediate trend) can be used as a buy signal.
我以为是在下方贯穿，死叉，选了b，如果是死叉的话这题会怎么问？
