No, I just look at the definition.
'T' If reporting a single protected transaction. A protected transaction occurs when a large order is going through the market. The buyer (or seller) may wish to keep the order anonymous from the rest of the market as the size of the order could greatly alter the price of the stock. With a protected transaction, the dealer will put the trade through in small quantities rather than knock the whole order out in one hit. The entire transaction is reported once the deal is completed. The LSE is notified at the start and at the end of the transaction. However, the market as a whole isn't told until the end, thus the order is protected.
Couple of things make me think all the recent AH are related to a very large (100M+) transaction. Today's AH was nothing special in volume -why reported AH?
Then again, consider past AH:
Nov 10 9.8M@.0005 when bid=.0006 and ask=.0007
Nov 28 9.0M@.0003 when bid=.0004 and ask=.0005
Just a bad trade or a previously negotiated rule?
Also, this does not seem an uptick or downtick as the stock will open at .0003 tomorrow - AH is "off-the-books"
Which of us is right will not affect the process going on -only who profits by it. Will be fun to watch.
