I thought I would try here before I ask this question at the TradeStation forums..... This relates to the Russell 2000 mini. My Matrix displays bids/offers 4 deep for the Russell. For those of you who use this to trade with....I constantly notice large bids/asks flashing in parenthesis for a nanosecond and they are gone. Usually when the action heats up and I am expecting a typical Russell explosion. I am assuming this is large instituitional stuff coming and going. Anybody else notice this or can enlighten me exactly what it is and why it never shows up.
