It Appears Games Are Afootwas looking at pre opening activity and noted matched buys and sells in the very low 8ths, that then increased....
I expect it is like the CSE where buyers put in fake bids\sells to influence the opening price and instil jitters of a share drop...in this case down to 8.05 then slowly rising in lockstep to where delayed prices still show 500 bid\ask at SH 8.21.
Could be wrong, but it is odd to see 500 for sale AND bid at the same price....rising in lockstep....and it is a classic move in trying to shake loose some shares
Opened at 8.47 for 571 shares....
