Re: Watch out for bugs
"A few days later the book was priced at some insane value - many hundreds of pounds."
Similar hiccups in automated stocks and shares trading have been blamed for unusual fluctuations in prices on the stock market too.
It's all well and good one or two make a killing with automated systems but once there's a few in the same ecospace, bugs in the algorithms or unexpected conditions where the same or different ones come into conflict can quickly cause a meltdown.
