How's this trade in TAP today? (see attached). Here's what happened, concluding 1/2 hour before the close:
* 11 orders (in 3 transactions?) sold at 35c or 35.5 ...
* for a total of 212,150 shares ...
* with an average order size of 19,286 shares per trade ...
* with an average price above 35
THEN
1 solitary trade for 917 shares at 32c, crossed (see "XT" in RHS column), at a time when over 720,000 shares had already transacted so far that day i.e. no lack of liquidity.

So, traders looking at Last Price"- TAP 32c, thinking what's up? You've got the stock at 32c, down 8.57% on the today, with good volume through (721,004) - doesn't look good, right? Except for the fact that the 8.57% price drop was caused by someone selling $293 of shares out of a total value to that time of $247,556!! Hmmm
