Spreadbet data


Junior member
Has anyone kept the Spreadbetting (any company - Deal4free, ig-index, tradindex etc) daily opening prices for ftse100 & DowJones indices ?

I'm trying to do some analysis, but need to see how the spreadbetters change the opening prices.

I have daily prices, but yesterday's close=today's open, which of course isn't always true when you come to place a bet.

Any help appreciated.



Dick Darstardly,
How did you do this? Was it through looking at their charts and manually noting the prices, or is there some sort of download that you can do? I too would like a copy of your xl file please. Thanks in advance. (I will try and send you a separate message privately with my email address)

I hold some of my UK100 positions overnight and I copy the closing price from my statement into my working spreadsheet every day. You can have this if you want, but I believe the closing price they use on the statement is just the final price of the FTSE, which you can download from yahoo. Of course it doesn't really matter what price they use because if it is high then your opening long bid will gain by the same amount as you lose with your closing short bid and vice versa.

If you want to know how the opening price differs from the closing price then with the rolling cash it is just a percentage of the closing price e.g.
closing price * rate / 365 where rate is something like LIBOR+2% - read the manual for the exact details.

You are affectively charged about 6% for the full value of the contracts you hold which works out at about 50p per night per contract for the UK100.

If you are holding monthly or quarterly contracts then the opening price is the same as the closing price.

Hope that helps,

Plavender, don't quite know why you say "how the spreadbetters change the opening prices". Their price(CMC), say the Dow (US30), is continuous (as Bonsai says) and based on the futures price before the stock market opens and while it is in progress.

This morning exactly at 9.30am NY time (our time 2.30pm) the'CMC' Dow 'opened' at 9723.
