Could you do a little bit of explaining ...and why you concluded that it's a fake wall...I would love to hear more...
As for me this is how I test it...if there are 3-5 MMs sitting on the ask...and if I put in a a few millions of ask-slapping but MMs cannot immediately fill my small couple of millions...then there is something wrong there...I did this a lot of time when SREH was in the 1s vs 2s part...then were ton of MMs on the ask...yet it would take them almost an hour to fill like 15 -20 mil. shares...
