which bot broker is buying off me ?

I bought 50,000 HEG at 1.18pm and put them straight up for sale at the same price, hitting the remaining 13.5c buyers, when i saw the buying support suddenly collapse...note the "trades" from that point on, i was the seller of all stock from then, plus a fake 100k buy bid appeared in the auction at 14c, and was pulled seconds before the deadline. This is what the ASX casino calls "normal trading" Maybe downside can find out for me which broker was doing this manipulation, they were trying to frustrate me into selling down to 13c, it was only intended as a day trade, now stuck with the balance 37,886 shares overnight.
