Overnight rolls

[Guest Paddyobiwan]

Hi does anyone know the charges for overnight shorts in Dow Jones - I had 20 short position and was charged 200 quid - seemed steep ? Also, if I square at 1 minute to close and re instate 1 min after close of Dow , I’m guessing I don’t get charged roll ?

Does anybody know how to calculate the cost of overnight funding, for example with a SP500 DFB spreadbet?

I have found some informaton on the IG website It mentions an "admin fee" however it doesn't say what this admin fee actually is.

so Dow is using the USD rate and USD uses 360 instead of 365 in the calc so the IG rate (commission and libor) is 5.02% for a long trade and -0.02% for a short.

so to give the the full calc for the cost of the long trade in the example above is; (£6.69 overnight charge for a £2/point bet.)  see calc below

 

 

And for the £2/point short in the example; -£0.03 overnight charge (credit) see calc below;

So for your own calc you will need to use your £/point and update the closing price, the commission is set and the libor rate is currently fairly stable.

Thanks @Caseynotes very help, I didn't manage to find that page.

I'll create a simple spreadsheet so I can calculate the funding costs myself.

@andysinclair, unfortunately the snippets of information are somewhat scattered so it is difficult to bring it all together and the IG Wall street example in the post above was in a recent update to changes for the Libor used.

USD denominated markets now use the USD 1 month Libor rate rather than GBP 1 month Libor and also calculate the year as 360 rather than the 365 used in GBP denominated markets. 

Easy to see why it all gets confusing.
