I think u are spot on SharifOz I noticed it last week as well as yesterday.
Exactly one minute after 800,000 shares were sold down yesterday around lunch time at 1.1 the bot starting buying at market first 1.2 then 1.3.
Im presuming like you stated the sell triggered the BOT into action, that is buying at market.
Interesting, I wonder how much they have accumulated and what their target volum is.
I hold.
