Other possibilities on the "bad prints": a broker/MM running stops, a broker/MM saving a few out-of-time executions to trigger TradeStation-type alerts.

I'm not enough of a rules-expert to evaluate the stops possibility, but have seen the away-from-market prints almost define intra-day highs or lows.

Using TradeStation myself, I've come to ignore many closely-set alerts because of the "bad prints" - but those prints do seem more systematic than quote system noise. Would a (large) trader reverse his position and intentionally cause the high/low prints to signal/trigger/jolt other traders into reversing also? With enough size, and a few jolt-able trading buddies, a few low prints might be an acceptable expense. Communicating via prints might also circumvent the SEC and recorded phone calls amongst MMs. Note that the airlines use the reservation system to play the signalling game in the air-fare arena.

Possible? Or paranoia? ( ... Andy Grove suggests that paranoia may be functional. <g>)
