[ReleaseCandidate] Module "GrapheneExchange" - Simple Python Trading Interface

[xeroc]

For those using this module: Please note that prices are now denoted in 'base'/'quote'. I highly recommend to read the latest release notes and the documentation:
http://python-graphenelib.readthedocs.org/en/latest/

Note that this release is not available via pip

[xeroc]

The whole thing is documented at
http://python-graphenelib.readthedocs.org/en/latest/
which is a page that is build from the content of docs/* and the comments in the code.

The graphenewsrpc.py file is to talk to the witness node via rpc.
the payload is constructed to follow the JSON syntax for calls properly:
https://github.com/xeroc/python-graphenelib/blob/master/grapheneapi/graphenewsrpc.py#L82-L86

[tonyk]

I know it is only semi related...

In graphenewsrpc.py

where can I find some explanation/examples etc.

payload in:

 def rpcexec(self, payload):

 is bothering me right this moment, but general info will be appreciated as well.

Will  add METAEX.BTC too.

Just need some more BTC and BTS.
Plus BTS to rise in price so I can borrow more BTC

I should probably do a check for unlocked wallet somewhere ..
Lots of other checks can be added for misconfiguration and similar stuff .. still in release candidate

Good to see it working for you now

Yes .. i noticed it too ..

thing is I coded the api too close to what poloniex is doing .. and they change syntax if you have only one market (compared to several markets)
I will definietly change this behavior ..

in the meantime .. just add another market for which you don't have funds ..

//edit: just pushed a new master that should change the behavior so that the bot works on one market as well

Good job, xeroc!  You are all charged up in a new year. 

[xeroc]

Could you re-pull from github then do

  make install-user

and try again?
