Qtstalker moves to Subversion

The Qtstalker open source charting and analysis tool project has been going through another quiet phase again (see my previous posts, especially about the out-of-date website).

Recently i assisted Steve to migrate from CVS to SVN. That has settled now. Awaiting further code progress.

Collaborating to build stock market trading tools

In a previous post i introduced the Australian Share Traders Co-operative, with our own funding and development of our TurboTrader tools for filtering and presenting live Australian ASX share market data.

The first stage of TurboTrader Mach2 was recently released, being the complete re-structure of the services. Performance has been robust, with new computing equipment assisting with the load of modern trading systems.

The new TurboTrader is a powerful browser-based solution, taking advantage of modern browsers to provide comprehensive configurable desktops and efficient data presentation.

It also has vastly improved Charts, for both long-term and intra-day time scales. The integration of the TA-Lib technical analysis library enables additional configurable chart indicators.

The Search facility enables the combination of various criteria to concisely present just the assets that are recently making movements.

The documentation is completely re-written, this time using a wiki so that we can collaborate to evolve that documentation.

With that infrastructure in place, we are now proceeding to fine-tune the Portfolio facility. This utilises the Searches in conjunction with a scoring system to gather assets that it likes, then selects and manages with buy/sell/hold rules, using actual live stock market data.

Please proceed to utilise the 14-day free trial, which enables use of the top-level of live services. Be sure to come to the Support chat-room where the group can assist with understanding the tools and the live trading opportunities. Or perhaps you are interested in the technical aspects of a modern HTML/CSS/AJAX browser-based application – feel free, we would love your feedback. Anyone can do the trial, but only once, so use it wisely.

Subscribers can enquire about becoming new members of the Co-op to assist with funding and building the tools, and to participate in the business. Foundation membership is still available while we build up the subscriber base.

As explained by the “International Year of Co-operatives 2012” this is a new way of operating: as a group collaborating to build their own trading analysis tools.

Qtstalker getting closer

The Qtstalker open source charting and analysis tool project has been going through a quiet phase again (see my previous posts, especially about the out-of-date website). However there are a couple of recent events that are encouraging:

Steve made another big CVS commit which settles the main new structure. I followed on to do some testing, and yes it does also run on Mac OS X. Now i gather that we are waiting for Steve to add some example scripts and some basic new docs. Then people like me can further assist.

Yes, the forums lists are quiet. Another one of those projects that has the good beginning of a community and a product. So when the main developer has been quiet for a while, it is delicate. Recently Steve posted regarding the benefit of open source and the need to compare results of technical analysis indicators in various systems and to compare available market data.

Glow Poi

We discovered Glow LED Poi at a recent festival. Fantastic for exercise and co-ordination, and for enjoyment. Started with doing simple things with only the dominant hand. Doing those same simple things with only the non-dominant hand is incredibly hard. After many months, now able to do a basic weave, which feels so good when mastered. Currently working on the reverse, before moving on. It is a meditation, as one needs to keep brain out of the way.

Incubator mail deluge

When the pressure is on, it is amazing how other seemingly unrelated things heat up at the same time.

We have the “go-live” for our new trading platform, which is big enough.

The Apache Incubator mail lists suddenly exploded. I am having trouble keeping up. The active discussions happen in the western hemisphere, first Europe then North America. In Australia we start our work day facing a deluge of past email threads. Slow down please.

Qtstalker gathers steam

Regarding the Qtstalker project, the open-source stock market charting and technical analysis package for UNIX-like systems: With my last post we thought that the new Qt4 version was nearly ready. There have been a number of different techniques attempted for enabling external programs (e.g. Perl, Python) to interact (e.g. for data loading and for indicators).

Now that is sorted, and the programs can be much more lean.

However, not yet ready for pre-release review.

See the notes at my previous post about out-of-date website, yet CVS happening.

Apache Forrest 0.9 released

We finally released Apache Forrest 0.9

In the almost four years since the last release, the Apache Forrest project has been ticking along with many bug fixes and consolidation.

Various Apache projects also use Forrest for their project websites. Among the many changes, there are also some useful documentation explaining how the Forrest project publishes our own project documentation via the ASF infrastructure and the download mirror system.

As usual, come to the mailing lists where we can assist each other.
