XT are usually just normal trades that happen to involve 2 clients of the one broker. It doesn't require your involvement in the arrangement. Eg I'm with commsec, I place a sell order for xyz, if they've got someone ready to buy at that price they can fill it and that's a cross trade. My understanding is that it can also be on normal market trades, eg John selling xyz at 1 cent, I see the price like it and take it, we're both using the same broker so it's a cross trade. It's not market manipulation.
