for the last two days, no market maker 00005s every time there is buying, it fills sloooow and fills at 0001 then the MM poots maybe 398 shares today and PPS lockdown at 000001
also
maybe deutsche bank fails next, but folks check it out. charles schwab owns interactive brokers and TD ameritrade.
my thought on what collapses first in the USA broker/hedge fund wise ....schwab.
