. . . I currently use IG for spread betting however feel a little uneasy as the prices are not from the real market as the FT shuts at 4.30pm yet you can trade through the night, something to with futures as a kind chap explained the system for me.
So my question is there a broker that is as good as IG but uses realtime prices of say the SP500 and FT100
Hi gtspeed
I've merged your new thread with this one as it's essentially the same topic and we have a clear policy of just one thread per topic.
In answer to your question - it doesn't make much difference which broker you choose as they all reference the same prices. The FTSE 100 cash index closes at 4.30pm regardless of whether you're with IG, City Index or CMC etc. The two key points you need to understand are these:
1. As Tom said in post #4, spread betting and contracts for difference (CFD) companies offer a 'derivative' product that is derived from the FTSE 100, Dow 30, S&P 500 etc. cash indices when they're open and then, when they close, from their respective index futures. In themselves, cash indices are not tradable instruments. Whilst futures are tradeable - you're not actually buying or selling a futures contract when you trade with the likes of IG - you're trading their
own product that is derived from the futures index.
2. When trading with IG (or similar), their prices
are the realtime prices and, if you open up the homepage of any major firm you'll see that their prices are all pretty similar. They may vary slightly as each firm sets their own prices using proprietary algorithms. But the source data - known as the 'underlying' is the same for all of them - so the playing field is level in this regard. (See the links provided by T44, above.) The other reason you needn't worry about any of this is because if the prices set by IG deviate markedly from those set by, say CMC, then
arbitrage traders would quickly exploit the difference.
For the reasons stated, when choosing which broker to go with - the issue you raise isn't an issue at all. The things that do matter that you need to focus on when choosing a broker are covered in this FAQ:

Let me know if any of that is unclear.
