GTM3442 thanks for the reply.
The website is halifaxonline.co.nz and they told me they have a white label partnership with Interactive Brokers.
Yes the lack of website info irked me too so I had to get emailed confirmation from them that there are no other inactivity, minimum account, exit fees etc (except they add +1% onto the spot price when making currency conversions), other than the low commissions listed on the website.
Where else would they scalp the ticket that I need to be aware of (as I said I am new to this so any tips greatly received!).
