Now you have no choice but to get average price for each time stamp and sum value for each time stamp before process trade data.

I can just do the weighted averaging within the SQL query. This might be okay for charts, but I'm not sure if a "calculated" closing price is a good idea for the overview page. For now I'll make the order fixed to whatever mtgox provided.

well... I believed that bitcoincharts.com shows each individual trade also from mtgox on the homepage. Then bitcoincharts.com could calculate the weighted average trade price and then create the corresponding point on the charts.

I'm not averaging trades, but I'm aware (and annoyed) of the problem. It's especially annoying for the last traded price when it jumps between 0.25 and 0.28 on every refresh. Not sure what I'll do to fix it, but it's on my todo.

Probably yes, anyway, do not be offended.

A few months no one noticed this problem or what? Forest of dots-trees?

It is not even about a specific problem but about people who create the weather on the market. Today I have "earned" $110.26 on the bitcoin market but I still see that then what we do here is nonsense.

I apologize if I am mistaken.

agree with your logic about the better accuracy if weighted price poer trade would be shown, ... but ... if you want good charts, why don't you go to bitcoincharts.com and get them?

you don't need to go to the nyse.com to get good charts

bitcoinex: What trading info is incorrect?

Open: https://mtgox.com/trade/history
Click on "Last 48 hours". Click again and again and again. You see little changes on the chart?

Your code do something like:
SELECT time, price FROM trades_history ORDER BY time;

But there is almost always a few trades have occurred simultaneously. More precisely, it is the same trade but with a lot of orders. That's why changing the chart. As a minimum, you need to add sort by another field.

But it says more about the problem really is. It is impossible charts with lots of points corresponding to one value of x, unless it's not trigonometry. People see total volume at every x point. And when traded offers contain one with too large or too small price, while showing a large amount of the transaction, they think that the rate has changed a lot, though in fact it is "sticking" the offer was met by ~0.01 bitcoins. I know at least 2 people who trying use it to rate manipulations.

For each x point (each trade) is necessary to calculate the real value of the price (weighted price, for example).

This also suggests (to me) about that 99.99% of bitcoin users is monkey-profiteers and the next six months bitcoin had no prospects. That's why the last few days I write these evil messages. Angry

+1 MtGox

You are doing a great job, and you have been doing it for free for many months. The trading on your side works best, according to my colleagues and friends.

Probably there are some people here just jealous who have almost 0 volume on their exchange.

Keep the great work up!

Of note: Yes, the site could be improved, but I am sure that MtGox would be happy to take contructive suggestions of active help, rather than people complaining about it all the time. People complaining are cordially invited to create a competing exchange if they think they can do it better.

.. sorry for the hard words, but many of the above is just very unfair.

IMHO, this is a very special paranoid. Javascript no less shit than the flash. But the flash, at least in theory, can run in a sandbox.

so can javascript - if you run the whole browser in a sandbox

which is the only type of sandbox i'd trust with flash, too heh.

but anyway - i completely agree, both js and flash are annoying, and i'd be very happy to see a nice static-html trading site. you can have a 'special' js or flash live-ticker, or live order book display, or live-updating chart... but besides that, a person should have complete functionality without flash or js.

in my book, if it's not automatic-live-updating... there's no call for requiring flash or js.

But so very well solve the problem of time zones. (If this a problem, of course)

problem with mtg is it uses javascript... but the order book and charts are not live-updating (as in, page has to be refreshed, or button manually clicked, to refresh the view). so it's like the worst of both worlds on this issue. but it is a very nice and functional site in other respects, and has a relatively deep market.

It's a horrible site and is popular due to a misunderstanding. Community still regret it because gamble with LR will lead bitcoin to a deadlock. hehe

I don't doubt that you are correct, but so am I. People have expressed a reluctance to use your site because of the need for flash.

I also do not like flash. But it works here and I do not spend hours to get diagram displayed.
And I also know many people who says that mtgox absolutely incorrect shows trading info. But everyone loves mtgox because it's such darling! Ugh!

Why you do not use flash charts? They are ready and free (small ads in the corner) and works fine.

Many of us don't trust to allow flash to run.
