Mtgox' API is going wacky all the time. All the charting sites are having trouble as well in getting reliable feed. If the feed isn't reliable, Bitcoinica prevents any trading from happening until the feed is back up.
by then the market could have moved way beyond reasonable. didn't i say this?
Yeah agreed. It's idiotic Mtgox is handling millions of dollars a week, yet they can't even get their API right... Unbelievable.
MtGox API is in migration or something like that, I think. I'm messing around with coding a trade bot, and I get the "deprecation notice" every time I run it, talking about how the API will be changed starting 3/1/2012. All this means for me is that I have to use some different methods, but hopefully this will also mean more solid connections for the charting sites (and whatever sources of info traders use that depend on Gox).
