Bot orders disappeared before late buying. At one stage there were shares for sale at 6.4, never got touched. Low for the day was 6.8 before a late larger order at 6.9. I wonder if the late buyer is the same as whoever is running the bot.
With a shareprice at around 7cps, can't see a low ball raising happening. Reckon if someone wants some volume there might be a few seller in the 7s, not getting mine though
