Story on one trader making a killing in 5 hours I think that for every one big bet that is successful, 29 fall by the wayside into oblivion. We can tell from the strained faces of the traders in the firm, of the stress and strains of recent market action, and it probably is not from making a killing.

Heard another story of a trader taking positions in crude oil futures, the first big bet landed 0.5 million profit. Next trade the market went against the position of 600 contracts. Result in topup margin of first night 2 million then 5 million the next..... It looks easier than it really is....

To make such killing, or wipeout, it is a matter of good(bad) luck, not skill...
