TomTom,
Heres the thing, more of a problem really. If they refuse to close the position.....what if the market continues to rise in his favour. The bookies dont know what the market will do next just like a trader doesn't. I agree with £10kloser here. Sounds like another made up story that probably started off with £1pp and turned into 2000 pound per point.
Also, if he's trading at 2k a point, why not go direct access....just a thought. I mean this guy you talk about MUST BE a millionaire. On most margin requirements for an index is roughly 150 per 1 point bet, so 2000 would be margin of 300,000 plus whats needed to maintain the position until close. We also know that people shouldn't play with money they can't afford to lose so I assume here he must be a millionaire several times over. That or stupid.
