Another reason to just have artificial delays in trading. If every exchange had a minimum of, say, a minute after an order is submitted until it is executed (during which time it couldn't be amended or cancelled of course) it seems you would greatly reduce the risk of "flash crashes"and unnatural manipulation of the market.
I know "market liquidity" is an argument for allowing HFT, but haven't hard a good explanation about why the economy would suffer so much if the ultra high frequency trading just wouldn't exist.
Note: I have about as much knowledge about this as people who suggest how SpaceX should improve. Just sayin.
Of course computer systems everywhere will have issues with an extra seconds (deltas being negative that can't be etc) but most of those systems aren't trading systems. Why is it that "markets" are in the focus of this? At y2k we were worried about planes falling out of the sky. Surely there must be worse things than stock market computer systems being confused?
