Its interesting, ive noticed a couple of times when topping up, I'll check the sell depth, and then when my order is placed, its like some sort of BOT picks up my order and effectively additional sell orders come through after i submit my buy to match it/cap the price. Then you see the strange 1 share trades today that move the share price up and down 4% plus, and wonder what the hell is going on!?

Then, you look at how thin the sell side is at close of market, and it looks on the surface to be so thin !! (until you put through a buy order and it gets matched)
