the style of graphs on the main page differ from those on the individual asset pages (prices as diamonds versus candlesticks).

Yes. The space was not judged sufficient to actually make any useful candlesticks (both because finite-pixel rounding errors and superimposition with volume bars) and also due to the litany of symbols on offer candlesticks might have been significant load. But other than the fact vwa prices are shown as dots (diamonds) there's little changed, scale works the same exact way.

Actually the drawing is wrong in one point, which is to say the low point on the price scale should read 2433 not 2043. I hope for my sake this is obvious enough and I don't have to redo it.

Yes, that was obvious enough, and I thought not to mention it.

It does appear, though, that the style of graphs on the main page differ from those on the individual asset pages (prices as diamonds versus candlesticks).

Small steps up is what we're all about

Scaled from lowest bid in 30 days to highest bid in 30 days. How could it go out of scale? Here, I made you a little drawing:

.

Do you mean lowest trade to highest trade? I thought you meant lowest/highest current bid, in which case it could go off scale if day 1 bid ask is 0.1/0.2 and then by day 5 the price has quintupled and bids are now 0.5/1.0.

That drawing helped. It still took me a bit to get my head around, but I understand it now.

For the Windows users aegis has complied the python script into a stand-alone all inclusive (gpg too I think) 32 bit .exe. You can find it here

Correction, you do still need GPG installed and in your %PATH. I just added the (Intel) Mac binary .app of Azelphur's frontend for OSX.

Yea, that info is going into the FAQ. Vertical is MIN bid to MAX bid (so in the case of the link, 122000 to 169000) and horizontally each line is a 24 hour interval starting with the present moment and going back. The volume line is also by days, the last bar being the past day's volume (so in the case of the link, 28500). Knowing this would you still say it is meaningless?

It goes from "meaningless" to "difficult to understand"/"not readily obvious". So a small step up.

So if the vertical axis is scaled to bid, the trading history could go off scale if there are large movements in price.

Proudly announcing the new candlestick graphs, visible on individual asset pages (http://polimedia.us/bitcoin/mpex.php?mpsic=F.GIGA.ETF for instance).

Scales on the axes would be nice. It's a bit meaningless without them.

From now on you can trade BTC/USD options on the MPEx infrastructure. Of particular interest is the newly added command SPLIT. Quoting from the FAQ:

Quote

SPLIT, as in SPLIT|{btc}|{option id}, which allows you to split a number of whole BTCs into CALL-PUT pairs for a given strike. Say you want to sell short 100 CALLS struck at 5.0 expiring this month. Provided you have 100 BTC in your account you go SPLIT|100|050T and voila, you now have 100 CALLS @5.0 (and a number of PUTS @5.0 based on the strike/current BTC/USD ratio), which you can sell. At the month's end you will receive the 100 BTC back, minus any costs resulting from exercises.

As you can see, this is a significant improvement over the way short selling works on the old MPOE site.

As a result the MPOE site is being retired. Customers currently holding options (long or short) on MPOE can ask to be migrated to MPEx (provided they have a registered key), but are not required to do so: contracts will be honored as they are at any rate. MPOE will stop taking new orders sometime in the coming months.

I wrote a little command line front end to MPEx to make it a little easier to use.

Thanks. Just got this set up. It makes it easier. A GUI would be better still. I'm sure it will come. GLBSE started as a CLI too.

release something like it that make MPEx easier to use.

If you're on linux:

That way the CLI directly spits out the gpg stuff you need to paste into the box. If you would rather it also posts it directly you can replace that last line with

(haven't tested but should work roughly speaking).

Simple page + GPG security ftw

YE!

Would be pretty cool to see a gpg based exchange for sure.
