I'm posting as official fits:
-80% or more tickets on the Over (or Under)
- total set by books (ideally sharp-ish) unchanged to changes by no more than a bucket
-correlation to sharp dollars being opposite the 80+%
- not distinguishing amongst moves and generally calling them flat bets
- not necessarily worried about ticket number but ideally early afternoon gets enough action but not oversaturation
- actual dollar amount being in favor of our opposite side is usually required but not entirely pertinent i.e. 1k bet from a sharp may move a line where a 10k square bet keeps it pat
