Can anyone explain to me what is going on with some trades in ABU this morning? If you can see the Course of Trades, you will notice one trade of 500 shares @ 0.051 followed somewhat later by 3 trades each of 10 shares @ 0.051. All other trades have gone through @ 0.050.

What are these 10-share transactions? Do they represent large undisclosed transactions (What used to be marked as 'U trades" - do we still have U-trades?)? Or do they have something to do with 'dark pools'? Are any of these operating as yet?

I was under the apparent delusion that you could not trade shares worth less than $500, that is, that the minimum trade was $500. This looks like some form of manipulation.

Anyone got any explanations?

I sold my lot at 0.050 and no longer hold. I'm just curious.
