as long as 'investors' keep placing sell limit orders on EDIG and trailing limit orders, the mms will walk the price down to fill orders.

Is there any other reason why there was such a b/a spread earlier and then when there were enough shares to fill the order, the ask went down?

Joe Investor (you and I) were not allowed to get in the way. Not at the "typical" ask, anyway.

EDIG reaches breakeven point on EPS last quarter... you can bet someone wants your shares. They just want to create enough FEAR, UNCERTANTY and DOUBT in the share price for us to buy the shares at this point.
