breakout, page-8

i was watching the sell side and at 2.94 2.98 3.00 .302 3.05 (not exactly those pricesbut more or less ) but at one stage they all appeared with sell orders at 15,000 shares they then changed to 2.500 shares all at the same time, then they all proceeded to change to exactly the same price but different amounts a number of times.

The question i ask you is why are all the sellers selling the same number of shares and changing the amount at the same time ? i have heard of synchronized swimmers but synchronized traders how cool.
