I don't think wide stock-market indices are supposed to wiggle with that sort of frequency; I assume it's a Bug at FTSE, since the charts from the BBC and Yahoo are essentially identical, but someone in London must be running around like a headless chicken trying to sort this out.

Yes, I was wishing I was at home to take advantage. What is odd is, it was clear which stock was screwing with the FTSE100, but the 250 was the same.

It wasn't at all clear to me which stock was screwing with the FTSE100; AB Foods (is that the first stock alphabetically by ticker symbol) appeared fluctuating by 50% from time to time, but the graph for that stock alone at the BBC looked reasonable, and the fluctuations were downwards whilst the FTSE100 errors were upwards.

This doesn't seem to have been an error associated with volume, like the 27 Feb screw-up at Dow Jones.

I'm not very trusting of the BBC site, having once seen it render a two-for-one stock split as a 50% decline in the stock's value - I checked whether AB Foods was doing a stock split and they didn't seem to be.

Is this kind of error something one can take advantage of? I'd have thought companies offering spread-betting would have realised instantly that something was screwed up and voided all transactions.

Betfair probably didn't void all "Daily Close: Up or Down" bets. I dunno I haven't checked.
