[with patch, with spkg, needs to be rebased] finance - Implementation of Sage interface to opentick

[cswiercz]

opentick is a collection of APIs for obtaining free real-time and historical market data for trading systems and trading platforms. With these APIs, we will enable Sage to be able to stream and manipulate real-time market data.

This ticket depends on #3621.

Ignore that patch. Messed up with hg. Accidentally overwrote a patch that this one depended on.

Typo. Put the files in OTHeaders.tar.bz2 in /usr/local/include, _NOT_ in /usr/local/bin.

Hi,

please do not attach binaries to trac tickets since those will be backup up daily until the end of time :). I have deleted both the library and the headers.

Instead link them from the safe place, i.e. you sage.math account. In general your approach is completely wrong. What you need to do is to build an optinal OpenTick?.spkg.

Cheers,

Michael

This ticket comes with an spkg. Alas, I don't have administrative privileges on Trac so I can't attach it here. You can find the spkg on sage.math at /home/cswiercz/opentick1.1.spkg. I will also post it at the top of  http://cswiercz.blogspot.com.

For the documentation in the patch sage-3573-opentick2.patch, here are some possible fixes to typos:

1. The word "minutely" is usually associated with considering something in close details. The expression "by minute" (or something similar) more accurately describes a time interval.

   -data on a variety of time intervals: hourly, minutely, or even
   +data on a variety of time intervals: hourly, by minute, or even
   

2. Again, a similar comment to that in 1. applies here. I would use "by second" or something similar, but not "secondly", which hardly describes a time interval.

   -hourly, minutely, and even secondly. To enable use of opentick, enter
   +hourly, by minute, and even by second. To enable use of opentick, enter 
   

3. Again, a similar comment to that in 2. applies here.

Disclaimer: I'm an Australian, so maybe my suggestions don't make sense.
