$SIGN 1Hourly trading volume rose to 6.2 times the average, with the price up 6.4%.
After a surge in volume, there are usually three things to watch:
1) The direction of the price movement: upward
2) Whether the higher volume continues—one isolated spike can be a one-off
3) The high and low during the high-volume period, which often become key short-term levels
Where do you think the key levels are?
