Are there any holders out there?, page-21

Can anyone here help me please?
I have been purchasing a few other shares and Dundas minerals lately but I have noticed some weird shite when I place an order to buy shares.
In a split second my order is trumped by another buy order of similar magnitude.
I do a fair bit of trading and this is starting to become noticeable and annoying.
Could just be a huge coincidence but today I placed a 20c x 42000 buy order at 15:59pm and 41730 beat me to it.
Is this a machine I am fighting with or did one of you guys just happen to buy at the same time that I wanted in?
A reply by the buyer much appreciated.
