Are you trying to imply that this didn't happen when computers weren't involved? Like the traders in the pits were all keen to make markets when volatility was spiking and prices were dropping?
- j_lev 11y agoI am saying that if you're a self-styled market maker but only bidding for the 99.9% of the time when the market isn't in free-fall then the "social utility" claim is dubious. People who place stop-loss orders would not do so if they were faced with an order book with no bids. However this is effectively what happens when the market starts to drop and the bids are all pulled.
