原理:读取中美市场价格，结合汇率，得出当前市场价差，当价差到达一定数值，则进行中美市场同时低买搞卖的对冲操作

汇率的获取因为yahoo服务器的不稳定，有1/3的几率会获取不到，所以改设一个固定汇率

version 1， 仅在终端输出两个市场的价格，标明当前哪个市场属于低位，以及价差的百分比

代码:

import os
import json
import urllib2

huobi = json.load(urllib2.urlopen("http://www.btc123.com/e/interfaces/tickers.php?type=huobiTicker"))
hbprice = huobi['ticker']['last']
btce = json.load(urllib2.urlopen("http://www.btc123.com/e/interfaces/tickers.php?type=btceBTCUSDticker"))
btceprice = btce['ticker']['last']
#usdrate = json.load(urllib2.urlopen("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20(%22USDCNY%22)&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback="))
#rate = usdrate['query']['results']['rate']['Rate']
rate = 6.04
x = float(hbprice)
y = float(btceprice)
z = float(rate)
w = y*z

if (w<x):
small,big=w,x
else:
small,big=x,w
result = (big-small)/big*100

if small==x:
low = "The Lower is HUOBI"
else:
low = "The Lower is BTCE"


print "HUOBI PRICE",x
print "BTCE PRICE",w
print low
print result

version 2  设置了百分比trigger，当市场价差到达trigger值，则在安装了Terminal-Notify的Mac 10.8以上系统弹出系统消息窗口，当前是使用了Automator在后台无限运行

def notify(title, subtitle, message):
    t = '-title {!r}'.format(title)
    s = '-subtitle {!r}'.format(subtitle)
    m = '-message {!r}'.format(message)
    os.system('terminal-notifier {}'.format(' '.join([m, t, s])))

trigger = 2.5

if result<trigger:
print result
else:
notify(
    title    = low ,
    subtitle = 'Diffrence Percent is',
    message  = result
)

还需要做的

找一个更好更快更稳定的汇率获取点； 实现email发送trigger以后的信息到指定邮箱； 把市场差价的百分比弄到小数点后2或者3位；让这个python script自己运行而不是用外部方法重新执行； 在路由器上运行这个script

原来那个自动换桌面也是LZ做的吗？

没啥基础，边摸边写的
