Quote from neekoryan:
2. Tried to go long here and didn't like the action so I exited for a 2 tick loss. No problem. However, that big 25k buy order went thru and it got me thinking. So I went long just before the drop and took a full stop there. Disappointed I didn't listen to myself and instead let other factors influence my decision.

I often wonder about the validity or usefulness of large orders at the Bid or Ask as an extra signal for entry or exit. I know that Anekdoten of AHG fame has posted some remarks about watching Time & Sales at entries. However, I personally find it confusing as I have seen time after time again, large orders being filled at the B/A do not portend direction.
I think that perhaps some arbitrage programs are buying and selling large blocks of futures & underlying stocks or SPY's. if they have the opportunity. I am leaning towards not watching the Time & Sales at all as I tend to become more confused and may miss my entries for that reason.
