Beside big investors going on vacation, I think the big red candles or big green candles are not strange situations analyzing the market, however, red candles could signify that the market is moving toward a correction, a dip price, and or a bear run.
I think there may not a total bull run without some dip, correction, and short bear red candles. Like I said in some posts, we may not experience a long bear run in 2021.
