I have unsuccessfully tried to find the answer for hours and now turn to this board for an answer. It will be most appreciated if you know and you answer.🙂 On the demo portfolio, the deposit on SB for Tesla is so high, it , for me at least, is not viable. And yet, if I try it on a CFD, I can easily afford it. The CFD quotes the real $ price for Tesla and the SB platforms breaks it down into US cents it seems. £1 is the minimum per point on both platforms. Why the difference? Am I all wrong or am I correct that I should go the CFD route? Many thanks.
