Today I made some major progress in the code:

1) I now track price history and enable users to query via API the information necessary to build a candle stick chart.
2) I integrated the import_bitcoin_wallet api to load wallets from Bitcoin Qt
3) I integrated the scanning of the blockchain for outputs claimable with a PTS or BTC address.

Tomorrow I will be testing these features and will prepare to launch the next round of tests complete with instructions on importing your bitcoin-qt and protoshares-qt wallet and a genesis block recently generated.    I do want to investigate the attack presented by alt prior to launching this test (as tests are time consuming to launch).

No, It's not the business about real USD.

bytemaster，now you would like to send me 25 PTS，or 23PTS and 2PTS to some Interpreter.

alt又把人绕进去了，变成先鸡生蛋还是先蛋生鸡的问题了。

很简单。其实，只要系统强制要求ＢＴＡ必须按与当时实物Ａ价格挂钩的方法，规定用法币在系统外或系统本身设置的接口兑换取得ＢＴＡ，系统内ＢＴＡ数量是有限的（从小到大）。这样，没人会拿用真金白银买到的ＢＴＡ出过高的价格买你的天价ＢＴＳ，更不会出现所说的上亿个无抵押ＢＴＡ。BTS是系统内已有的（也是有成本的），BTA是外来的（不是凭空产生的，而是用法币买的），alt推论的前提不成立，推理无立足点，结论自然错了。

current price is 1000usd/bts

here is the buy order:
buy 1000 usd with 1bts
buy 1001 usd with  1bts
buy 1002 usd with 1bts
.....
buy 1100 usd with 1bts

anytime I can give a buy order with
buy 1000000000 usd with 1bts
And I can give a short with
short 10000000000 usd with 1bts

So there is a line of people each wanting to buy about 1000 usd for 1 bts ....
And along comes someone who wants to sell 1000,0000 usd for 1 bts....

Assuming he actually had this usd (ie it was a long/long sale) then the market should match him against all of the buys (4103 usd), give the seller his .0001 bts and earn 3.999 bts in fees for the network because the seller was an idiot and sold way below market.   

Now in the event of a short position the result of this move should be...

Buyers get 4103 usd and the short seller ends up short -4103 with collateral of 4 bts (from buyers) + .0001 bts (from himself) which would seem to justify a margin call immediately... thus  I need to adjust the short-sell code to always use the price of the bids to determine required collateral (bts) or this kind of abuse could carry on.

Let me look into it a tad more and if it pans out I will send 25 PTS your way for finding this.
