To gauge how significant a piece of news is, I only compare trading volume before and after it.
Take this one: a smart-money address has once again reduced its VVV position, with estimated profits of over $9.84 million on the token. $VVV (24h -9.06%), trading volume: 40.16 million.
A mildly bearish signal. Keep an eye on support below; if it breaks, lower levels are in view.
