The 0.0035 or 0.0045 etc trade would have to be done as a Centre Point trade - ASX Centre Point is Australia's largest and most liquid anonymous mid-point matching system, matching at the mid-point of the national best bid and offer. I don't know if Self-Wealth can put a Centre Point trade in for you, you would have to call them and ask.
NAB Trade can place them but has to be done by phone request.
