A break over $6.50 confirms a run over $7 on the day will occur. (you were blocked by rookie shorts) Volume will come if BOSC can break over $6.30 again... currently only 200 showing shares at $6.04, 100 shares at $6.19 and 400 shares at $6.25 block the route. 600 showing shares. A large enough bid jumps this and turns itself into profit right away with volume turned on.
Volume on up moves is easy to see. Accumulation here is the game for some.
