Seems like a question that needs to be posed...
Why do intended sellers jam the sell side and cause stocks to fall by massive amounts?
I understand that traders need to sell their stocks at specific prices, but why do all traders jam it up then watch the stock price fall.
Is this a "Panic" trading system? OR is it a method used to lower the price to re-purchase back into a stock at a lower price and hence buy and own more of that stock.
A better solution that seems more logical but only in a perfect world would be to place sell bids in such a less panicked state, and hence the price moves slower.
This would help long-term shareholders not suffer the crippling ups and downs of stock movements but I understand it would destroy the objective of day traders.
