Topic: How old is the MtGox 'last' price? (Read 698 times)
Thank you, TangibleCryptograhy. That helps a a lot! That gives me a bit more confidence in using it for product pricing/conversion,
It is based on the last trade. 
It could be a fraction of a second or it could be hours (unlikely).
It is rare for there to be a period of time with no trades longer than say a minute.
It could change very very drastically in 30 seconds especially in a panic sell. Generally speaking the intra hour volatility is much lower these days.
Taking a look at a chart might help you visualize the swings and frequency of trades.

When I look at the 'last' price at MtGox, I'm wondering how old it is? Is it refreshed each time the page/API is called or on a timed basis? How strongly can I rely on it for the current Btc price without worry of it changing drastically in the next 30 seconds or so?
