I usually mark the time a piece of news is released on the intraday chart, then watch what happens.
For example, this one here: a loss of about $1.61 million on a swap; a whale exchanged 16,700 ETH for USDT. $ETH 24h -5.61%, trading volume: 793 million.
When the news is bad, I pay more attention to whether the previous low will find support.
