Some interesting price action today. Wasn't a lot but what was there looked suspiciously automated (more noticeable due to the complete lack of action over the last few months). Even the closing auction, 146,232 were placed in the sell que @ 6.1c and then just before the close someone placed a buy order for 146,231 @ 6.2c to ensure they got the max amount they could but still at 6.1c.

Wondering if it is just someone waking up to the mispricing due to their LEL holding, or whether maybe something is starting to bubble in the background with the iron ore.
