News: Australian PM John Howard got caught making risky gestures on the tradefloor, oblivious to the gesture system around him.
Check this real trader gesturing in the crude oil pit, or some more pictures. I wonder, will such nice gesture systems, used by future and stock option traders on the trade floor, vanquish with the advance of computer trading?
In the Netherlands, this already happened. The last of the traders at Euronext to disappear behind a monitor were the option traders, in 2002. In the US, floor traders and specialists are apparently still very active and secretive gesturers. The SEC installed cameras to fight illegal prior knowledge transactions. Such transactions are often preceded by gestural communication between traders with inside knowledge.
