If Mr Whale wants to bet £1000 on Tesla. That requires over £6 million in margin at todays prices.
So Mr Whale needs to put up £6million.
For Mr Whale to be considered a consistent loser, he would have already have had to have lost £10 million+ to the spread bet firm already. Anything less might not be enough for Mr Wale to flagged yet as a big time loser based on the size he wants to do.
So yeah, if he has already lost £10 million to the spread bet firm may well take the other side of his trade next TSLA at £1000 a point. If not they will hedge most of the risk off in the underlying.
