yeah. i dont use it as a trade signal obviously.... just to help alert dangerous "possible" reversal areas.
the biggest size i ever saw in the ES was 1589, moved the market for 1 second down, then it went up again several points (did go down for the day though) makes me wonder who has enough money for 1589 contracts
today i saw something like 174 print on the ER2 t&s.. there were many big prints today now that i think about it...
