A "bad tick" is just some erroneous information or noise that has sent through as trading data.
In the data it appears as a spike that is "way off the scale". It just looks unreasonable. Sometimes however traders do make mistakes or stops going off take some prices to a ridculous levels and it is can be hard to tell bad ticks from bad trading.

Hello All
I have come across the term "Bad Tick" a lot. Can someone tell me how a data tick can be bad?
What to look for in a data feed? How to compare one feed to another?
