I understand the graph as shown by btc-e has the following info:

* volume of trades (the bar height)
* value of BTC (the height of the red and green blocks)
* the variation in buy and sell value (the actual size of the red and green blocks including the black line)

however, what is the meaning of the red and green color? I would think green means up and red means down but sometimes there is a red block higher than the previous block.

there refferd to as "candles" the colour is judged by the closing average red means the average was lower than the last candle green means it was higher the height of the candle is the highest and lowest trade that was successful in that candle period

Sometimes the candles can turn into fires and everyone shouts arize chikun

green = price going up, red = price going down, each stick is a given time span. the bars coming from the bottom are telling you how much volume (how much was bought or sold, denominated in bitcoins)

 :)

Yes, the red means the price is going down, green means the price is increasing.

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.

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.
