word of a true master of trade-- i bow to you sensai!!
It's ALL about NOT panic selling. The MM delibrelately stack sells together into the biggest pile they can and then execute them all at once which will naturally make the super computer lower the B/A and as soon as they are done doing this, all the BUYS they accumulated while they were posting the sells are then listed all at once which of course drives the ask price up again.
Buy and sell with limits and pretend there is NO BID button. That every trade you make (buy or sell) has to go off at the ask. That's the way the PROS do it so stop looking to the MM's like we are all amatures.
if people would do this, the old days of multi penny runs would be plentiful....
The $2 deal sounds funny based on values of REO since I can value your house 50% less than current worth based on bank REPOS short sales etc. etc. in Florida and any other state combined . i tell you that 50% is a big deal and than you can wonder why all banks are going down the tubes and straight to the FDIC..
