I closed down my charts early, but from checking my cell phone it seems like the 'market makers' took a breather for a while and that we dropped about 45 points instead.
To be honest - I'm skeptical if there's any edge/precision to be found in speculating about how a dealer/specialist/market maker is positioned or
is positioning himself.
Even if you could know - isn't it also true that these guys are wrong too? And when they are - surely they'll be hedging their positions and adding more fuel to the fire...?
