Thank you but upon close examination you might notice that your link doesn't answers my question in any way (nor any of the links therein).

I got how to read a candlestick chart, what I'm unsure about is related to specifics of btc-e (or at least btc trading), namely :
- The unit of the trade volume bars
- The specific meaning of the four values displayed when highlighting a candlestick. Obviously those are open/close values, but I want to be sure why there are four of them, if it corresponds to the bid/ask or something like that ; moreover, I still don't see which of those four values contribute to determining it there is an upward or downward trend (and hence the color of the stick), and how. Moreover I'm perplexed by the fact that in some cases, the last two values are actually the first two values exactly but in reverse order (like A, B - B, A).

Edit : so I came to the conclusion that this is indeed "Open bid, open ask - close bid, close ask", and that what determines the color is the closing bid-ask spread. Still not sure about the unit of the trade volume bars, however.

I'm reviving this thread because I have further questions.

- Regarding the trade volume, what unit is it in? For example, if I highlight a bar and see "15:30 : 6.07526", what does it mean? That about 6 bitcoins were traded? Or is it in some other unit? (Btw I display the charts in terms of EUR/BTC, but I don't think it affects the trade volume bars, does it?)

- I fail to see a relationship between the color of the bars and the numbers displayed when I highlight them. Moreover, I have no idea what those numbers are. For example if I see "15:30 : 442.457 - 449 , 449 - 445", what does it correspond to? Like, bid and ask prices at open and close, respectively? Or something else? If it is indeed that, I fail to see so far how it affects the color of the candles...

Thanks for your help.

BasedForLife : it was useful in the sense that it pointed out to a relevant piece of information (I replied to you btw), but it didn't solve it, no. Given ChrashX's feedback, the problem seems more severe anyway.

CrashX : hahaha ok so now MtGox is considered a high risk investment. Good think I came asking questions here, or I would have missed that very important piece of news and ended up joining those guys : http://www.pcworld.com/article/2099620/mt-gox-protesters-still-without-bitcoin-answers.html.

Thanks MoneyMorpheus but the page you are talking about is exactly the one I'm referring to in my post.

CrashX, your reply is not very encouraging. But I'm increasingly starting to believe, given all that I read about MtGox these days, that maybe it's better that way : MtGox is increasingly unreliable and my money might be better elsewhere.

So I happen to have lost my MtGox password (yeah, I know). When I turn to the lost password page, and enter my e-mail, I get the following error : "An unexpected error has occured. Please try again later.".

Does anyone else has the same problem, or experienced it in the past? Any insights in this respect? Is MtGox slowly falling apart?

Thanks in advance for your replies.
