#2Wow, that's crazy! What algorithm did this, or maybe it's some scheme manipulation for profit? You can never be sure when something like this happens, flash stock crashes have a history that's muddy at best. :/

Stock tracking websites don't need to be perfect, just need to be better than the humans they replaced. Faster, free, and less errors doesn't mean they must be error free.

#7I've actually seen a number of times where Google Finance has a daily low that was never reached or a high that wasn't shown on the graph (sometimes many percentage points away). It's also notoriously bad when there's a gap up or down, and will sometimes cut out various parts of the graph.
But still, seems to be one of the better ones out there, as I still use it. Just don't treat it as authority.
Another interesting example of questionable data is the premarket CNN feed at (http://money.cnn.com/data/premarket/). I have sometimes seen a stock trading premarket down 99%, which almost always looks like an off by some factor of ten of the price.

On Bitcoin exchanges, sure. But here I think there's too much liquidity and automated trading.

Except these weren't real prices. Buy orders would not have been triggered.

Recently when BTC flash crashed (or maybe it was Ethereum) those who had placed such orders made a ton of money. It's a safer bet with virtual currency because of its instability
