DIN,
"I thought the Mr charts / NAZ approached relied heavily on being able to trade on the actual stock price and not for example a SB price". Correct, neither of them trade via SB; both have direct access accounts. Naz's point about GNI's CFD platform is that, potentially, it enables peeps like myself who don't have the $25K required to open a pattern day trader (PDT) account to trade the actual market price as opposed to the wider spread offered by the SB'ers, plus bias etc. If you're looking into this, tread carefully, as my understanding of the situation is that some market participants offer 'free' CFD trading whereby you don't pay any commission but you have to contend with an increased spread just as you do with the SB'ers. To my way of thinking, this is useless. I've not looked at it, but , by virtue of the fact that Naz mentions it here, I suspect strongly that the GNI platform will mirror the market spreads exactly - hence the commission charge. As for the advantages / disadvantages of CFD's, I suggest you do a search as there are a number of threads devoted to this subject. HTH.
Tim.
