Watch the SB price of the company you use to trade against against another price feed.
I do this routinely, actually. I've discussed it in other threads.

Enter your trade ... Then you are likely to notice that for most of the time your trade is positive, the company you used to trade with slightly lags the market. However, should your trade turn negative, you will notice that most of the time the company you placed the trade with is leading the market, so your stop will get hit earlier.
I've certainly never noticed it before. However, I'll look out for it, as you suggest.

It is highly probably that most SB companies offer a different price (spread), at any given moment, to clients who are either long or short, by 1 or 2 pips.
Call me naive, but my initial reaction to this suggestion is to wonder whether, if they displayed different prices to different clients at the same time, depending on the clients' respective positions, the FSA would close them down in hours, or only in days; and whether all the directors would go to prison or only the ones who knew that they were doing that; but I'll discuss it with an FSA official as soon as I can and report back.
Knowing the extreme care, diligence, inventiveness and imagination which the FSA bring to bear in routinely investigating, checking up on and generally policing the spread-betting industry, I'd certainly be extremely surprised if anything of that kind could avoid their attention for a moment.
I can also think of another way of testing out this theory for myself (which I don't want to describe in detail here in case anyone imagines that I'm potentially invalidating its result by inadvertently "tipping anyone off"), which I'll try out and report back on during the week.
Unlike some other people who post here on this subject, I'm always open to being mistaken and have no problem at all being proved wrong and learning something from that. I hope, though, that you won't mind my saying that I hope you're mistaken here!
