A shift in trading activity: $BIRB surged 7.2% in 1 hour
To judge who's buying, I usually watch two things first:
· Are there clusters of large orders during the rise?
· Do large sell orders start appearing after the price moves higher?
Cross-check: 24h trading volume was $108 million, up 47.26%. The first condition is met and the second isn't—only then can this rally be considered supported by buying.
