Wall Observer BTC/USD - Bitcoin price movement tracking & discussion

[Richy_T]

The problem with ChartBuddy is the 3D-effect. It's simply to hard to read (not hard to understand, just hard to read). I find Bitcoinity to be the easiest to read when I want to see the walls.

Fair comment. I'm not really sure there's much could be done to improve it though. I was thinking of making the rotation dependent on the price change over the course of the hour but don't think that would be immensely helpful.

I guess the question is, do we need an hourly chart and if so, what form should it take? Something like bitcoinity with maybe the 3D smaller and inset just for illustrative purposes? I don't know. I do know whatever I do won't be able to make everybody happy

That's simply a 3D graph, why is that so hard to understand? It's as easy as drinking!
There are only 2 defects imo:
1) the bot should check the thread and not post the graph more than once per page
2) sometimes (really often, in fact), the 1 hour timeframe is simply too boring. A 6 or 12/24 hour tf could be much more interesting.

My original thought was for the chart to be posted at the top of every page (or, at least, as close as possible). That was for a simple 2d chart though. The 3D complicates things as that would mean compressing or stretching the time axis over the period of time which is straightforward from a programming point-of-view but would likely make the charts even more difficult to understand.

a better, but also more complicated solution would be one that takes into account (1) changes in the graph (i.e. if nearly no change, don't post) and (2) number of human posts in the thread since last bot post (i.e. don't spam the thread)... probably too much to ask for to program this, especially (2), but one can dream:)

The problem with 2 is the unintended consequence. If there have been no posts for 8 hours, do you compress all 8 hours into one graph? Post 8 charts?

Maybe I should just make chartbuddy invokable. Call him and he'll post

Or how about if there are any major wall changes in the past hour? That would be a little more tricky to write but not overly so. (Actually pretty trivial to write but it's all in the definition).

only if it's some esoteric and complex ritual.

That's simply a 3D graph, why is that so hard to understand?

pseudo 3d on a 2d screen is the worst invention ever. the chart should be a (sort of) 2d matrix, where the height of the bars is indicated by a color coding. color-bar on the side as a legend tells you the amounts, that's all.

For what it's worth, since I've been lurking this thread for a few tens of pages (hundreds?), I like Chart Buddy's 3D representation as it shows the evolution of the wall over time and not just the last point in time snapshot.

It needs getting used to the first few times, but readability isn't bad.

And sometimes its comments are just better than the rest...

I don't mind ChartBuddy so much. It's nice to see the last hour of prices and bids against asks.

I don't like the idea of bots posting like this, it is just spam. The charts themselves are 99% unintelligible in my opinion.

Ban it I say, if the owner has something worth sharing, he can share it himself

I think he should fill them in to smooth surfaces and post a short video of how they evolve in time for the last 6,12 or 24 hours instead of all the instantaneous snapshots ... and rotate the perspective back slightly ... or have like a tunnel view down the center of the walls and play it as a movie as you fly through it (forward in time)

^^ this.

A gif would make sense.

Actually I made a gif a few days ago and it wasn't as revealing as expected, mainly  because the values on the price axis will move but the main line where bids and asks "meet" remains kind of static (bottom of the valley always in the middle of the picture) beginning with the first set of values.

Any idea of what I could add or improve ?
Cheers !

That's solvable by making the axis a fixed variable colour flowing throughout the whole spectrum. From image to image it would be quick and easy to spot when the axis has moved by doing this, and when it occurs gradually over many many images it'll look nice too.

Hey Chartbuddy.  Don't let em get you down.  They try to block everything and everyone they do not understand.  It's just human nature.  I know you are immune to human nature and that's why I love you.  Just look at me, my ignore is glowing like a Las Vegas strip club sign and I'm still here.  Stand strong...I got your back.

Why not just give chartbuddy its own site, like bitcoincharts/blockchained?

Looks very interesting, but somehow hard to read. I suggest to start a new thread to discuss further details.

Can you put up a higher resolution version? I can't make anything out.

Would love to comment...

Thanks, I opened a thread here : https://bitcointalk.org/index.php?topic=210202.0
It shows two examples with a higher resolution, I'll try to make a SVG version soon.
