Yes but you can tell by the prices being given how hard it is for them to replenish.
e.g spread is 0.85-0.90
buys coming in go...
100k @0.88
50k @0.89
200k @ 0.9
15k @ 0.9
when large and small buy order both capping at max offer (0.90) and sells are going through at/over mid you know mm's are struggling to find sellers at that level and its about to move up. Trust me ive been doing it 8 hrs a day for 15 years now. usually can call it within 30 mins of it happening unless a big seller resets the cycle.
