twstools - command line tools around Interactive Brokers TWS API ============================================================== This is a simple set of command line tools around IB's TWS API with the purpose of having a powerful scriptable toolbox to automate "jobs" like downloading historical data, tracking account info or submitting orders etc. The project homepage (bugtracker, latest git repo) is hosted on github https://github.com/rudimeier/twstools Released source tarballs download here https://bitbucket.org/rudimeier/twstools/downloads Binary rpms for various Linux distros here http://software.opensuse.org/download.html?project=home:rudi_m&package=twstools Project's objective ------------------- The twstools wants to be small, simple, _stable_, easy to use and easy to maintain. A general use case covered by the tool set looks like this: 1. Create a job file (for example "get contract details for 10 lazy specified option chains"). 2. Process the job file against TWS to get an output file containing the complete response without any loss of information. 3a. Parse the output file to get the information you are needing currently. and/or 3b. Parse the output file to generate further jobs from it (for example generate a job file to get historical data for the received 5000 option contracts and goto 2.). The input/output file format is very simple xml which can be easily generated/converted from and to csv using the tools itself or any other tools. Per design the actual job processing tool is completely stupid - just doing the given job but doing it very well. BTW the used xml format is intended to be independent from the tools itself to be used to carry all IB/TWS specific structs/messages for saving without loss of information and easy conversion to other existing TWS/API applications, see "Notes on the twsxml format" Installation ------------ Building from source requires a C++ compiler and libxml2 which should be available by your distribution. Tested compilers are gcc/g++ and icc/icpc. Windows has been successfully tested using cygwin. To make life easier pkg-config should be installed. Additionally we need to install twsapi from https://github.com/rudimeier/twsapi When building from git checkout you need the autotools and gengetopt and don't forget to type "autoreconf -vfi" first. ./configure make make install Now you may just try such quick shot like getting account info: twsdo -h localhost -p 7496 --get-account Note there is still a lot debug output on stderr. Just redirect it into files: twsdo -h localhost -p 7496 --get-account 2>bla.log >bla.xml Usage ----- Currently we have just two commands. The job processor "twsdo" and job generator "twsgen". twsdo reads jobs from file and writes TWS response to stdout. twsgen reads such response file, creates new jobs of it or just converts it to csv and writes to stdout. Note that both tools have not much functionality implemented yet, see twsdo --help twsgen --help Rather than using twsgen you may create job files using any other tools like editor, perl, sed, SQL, whatever. See example scripts in sample/ directory . Notes on the twsxml format -------------------------- The purpose of twsxml format is to keep the data received by TWS as original as possible. Doing something useful with that data is a separate process. If you will notice that you misinterpreted the data then you are able to fix that and parse it again. This is the main advantage about a directly connected database backend. The output files do NOT contain plain xml but serveral xml documents separated by '\f' (form feed) characters. The advantage is that you can use these files already before they are finished. And if a tool is killed/crashed then the half ready output file contains always valid data of what has been done so far. The disadvantage is that existing xml tools can't handle them. However it just takes one sed command line to convert them into plain xml. The twstools itself are able to handle plain xml input because this is just the special case where a file conatins one xml document only. Known issues / TODO (feedback is welcome) ----------------------------------------- Although particular use cases are working nice and stable twstools development is still in alpha state! The user interface and xml format is not stabilized yet. But don't worry all future changes will be made as compatible as possible.
