this is what I could find on the website:
The tightness of spreads can be critical to many spread betters as it can have a big impact on an individual’s style of trading.
Spreadex has spreads starting from just 0.6 in width on the SPX 500, 1 point on the UK 100, Germany 30, France 40 and US Tech 100 and 1.7 points on the Wall Street.
But this is what I got back from one of the support staff about overnight fees:
So for the UK 100 index our fee is 0.714 * stake. So the charge is independent of the current price of the market.
It sounds like you were more interested in the Equity side of things so let’s use an example of £10 per point of Barclays:
The close price yesterday was 179.02 and LIBOR is 0.70%. Therefore, the charge to your account would’ve been £10 * 179.02 * (0.007+ 0.03) / 365 = £0.18.
This would be applied each day at 16:30 with a 3 day charge applied on a Friday to account for the weekend.
this is also a selling point:
We do not charge you for holding an account with Spreadex or charge inactivity fees like some providers. There are no minimum deposit requirements, joining fees, contracts to sign or obligation to trade.
