Apologies if this is off-topic, but would be interested in other opinions.The other morning a bought a parcel of a particular stock - this trade showed up on the platform as XT, which I assume is my broker selling me shares from another one of their clients. Is this correct?Then I proceeding to buy a couple more parcels, in which I got the full allocation, but in the trade history on the platform (Iress/Nabtrade) the volume doesn't match what I bought, it is a fair bit less. Anyone experienced this or know the mechanism behind it?
