The prior low and key moving averages won’t change because of the news; these are the levels to watch.
Take this one, for example: ETH has stronger near-term buying pressure, with spot buy orders on one exchange totaling $14.0979 million, $3.858 million more than sell orders.
Wait for the price to return to the range it was in before the news came out. Only if it holds there will that show the news has had an effect.
$ETH is currently trading at 1909.19, down 4.66% on the day.
