纳斯达克综合指数的技术见解：On the hourly chart, the NASDAQ index tumbled below its 200-hour moving average (19,428.78) and an upward-sloping trendline during the trading day. However, it failed to sustain the downward momentum and rebounded to close between its 200-hour moving average and its 100-hour moving average (19,803.75).

下周展望：

• Trading 高于100小时移动平均线 would indicate a bullish short-term bias.

• Trading 低于200小时移动平均线 would signal a bearish short-term bias.

与这些关键移动平均线的相互作用对于决定未来几天纳斯达克综合指数的方向至关重要。

标准普尔综合指数的技术见解：On the hourly chart, the S&P index fell below its 100 and 200 hour moving averages and 6040.97 and 6001.31. That tilted the bias more to the downside. The low price for the week did extend below a swing area between 5853.00 and 5878.47, but the price quickly snapped back in trading today. The selllers had their shot and they failed.

进入下周，顶部的目标阻力将是移动平均线。下行的摆动区域将得到支撑

下周展望：

• Trading 高于200小时均线和100小时移动平均线 (green and blue lines) would indicate a bullish short-term bias.

• Trading 摇摆区支持would signal a bearish short-term bias.

与这些关键移动平均线的相互作用对于决定未来几天纳斯达克综合指数的方向至关重要。
