Comment Re:There should be a mandatory one second delay. (Score 2) 327
The method I have proposed to fix this is "cycle trading". Traders submit their buy/sell requests for a trade cycle that happens every minute. Each cycle's trades go to completion if possible, based on buy/sell amounts and prices (bid/ask). Requests will be left over if they cannot be bought or sold in that cycle. They can be flagged to hang in there for the next cycle, or canceled, or changed.
But instead of a one minute cycle, let's do a one day cycle.
