"Bunch of useless idiots! You're all a bunch of idiots!
How could our model get fooled by such a simple misdirection, without any stop-loss mechanisms? Is all the budget we give to your tech department each year just feeding the dogs?"
"Mr. Wei, of course, we have stop-loss mechanisms, but the quantitative model is just a rigid trading program. It can't optimally respond to every sudden situation.
If suddenly faced with a large number of sell orders that hit a critical point, the model indeed can make a misjudgment.
It is, in essence, a stop-loss mechanism to prevent losses from expanding, but we never expected
it would be exploited by our rivals..."
"Never expected? Is 'never expected' the end of it? Just because of one oversight by your tech department, we're working all year for nothing, don't you know that!"
"Well... it can't really be considered an oversight. Normally, no one could so accurately predict our model.
