To play devil's advocate:
- Can't failures be counteracted by having failsafe measures? For example, if the market goes down more than 5% in a few-minute period, the market temporarily shuts down for a cooloff period of several hours to diagnose what's happening.
- Isn't HFT irrelevant to long term investment, given that it erodes away short-term profit, leading to accurate pricing of the stock?
- hp50g 14y agoGood questions. A failsafe/circuit breaker is a possibility but shutting down the market will affect confidence. I'd prefer to see a market operate on a tick basis I.e all trades for a tick are transacted in one go with a window between each tick and assertions before and after the tick processing. Fair point with your second comment.
