In one case, flawed software and a fat-finger 10x pricing error caused the algorithm to keep out-bidding itself by 20 ticks, affecting the pre-market price. In another case, the software allowed a human trader to override the safety limit 3 times, which "completely defeated its purpose" and caused a 31% price increase in 36 seconds. In the final case, the safety limit didn't function because the software did not allow for the absence of an opening price, knocking a price down by 14%. Lucky buyers!
