What defines a market Crash?

What defines a market Crash?

I never been thru a market crash but to me Oct dam sure looked like the market crashed.. But I guess not... So for the people that been thru a market crash before, What defines a market Crash?

 

Totally subjective but for me it's a major index losing 20%... intraday. A very rare event.

 

I google the topic and found the following info that should help you define a market crash...

Thanks man for the info... Its funny how wikipedia is calling Oct 2008 a crash but the media hasn't said anything about a crash....

 

no bid side, and future market has its limit down in pre-market.
