Nasdaq 100- Strong reversal can lead to continuation

For more than a year now(since Sept 2020), Nas100 is trading inside an ascending channel, and dips around support of this channel were constantly bought.
The correction of this trend, started last week, looks over and we have a very strong bullish engulfing candle on our daily chart.
This candle can lead to continuation to the upside and a new ATH could be reached.
The upper boundary of the channel can provide resistance and exit point for short to medium-term traders and only price under 15.500 would be bearish for US100.
Buy dips is my strategy for this index
