Simple indicators TA trader


Simple indicator TA trader (as a configurable running strategy) – desktop GUI app.


This task consists of creating a simple application which will serve as an example to individual developers. Although limited & exemplary, the application must be fully functional. I will be available freely in the AppStore mentioned above, along with its source code on an open BSD-like license.

All thanks to the independent Application Programming Interface platform allowing a secure connectivity to new FX platform called xStation ([url removed, login to view]) which gets more and more popularity among brokers, including XTB, xDirect etc. What is more, the released API enables to create autonomous software improving & extending functionalities already accessible through existing Desktop, Web & Mobile clients.

The application will be connecting to the Broker’s transaction server through TCP/IP API using two bidirectional sockets. Socket 1, called RR-Socket will serve as a channel for request-reply communication for simple functions and Socket 2, called Streaming-Socket will serve as a channel for streaming subscription & streaming receival in case of frequently changing data such as market prices & order updates.

The API packets are encoded in simple JSON, and are really straightforward to use. You will find the necessary specification attached. For development & testing purposes you will connect to a demo transaction server.

Your goal is to create a simple desktop application listening to market prices through the Streaming-Socket, computing indicator values chosen by the user & evaluating the rules defined by the user & generating BUY/SELL/CLOSE signals.

Necessary indicators (you may use an open-source Technical Analysis library of your choice, e.g. one of those: [url removed, login to view]):



• Momentum





• Acc/Dist

• Stochastic Oscillator

Necessary functions:

• Defining rules with: >, < = Between, Crosses, AND, OR, NOT)

• Rule (logical expression of indicators & relations), may be wrapped in DURATION or INSTANT

• ACTION – BUY/SELL/CLOSE, and how much, when a rule is met.

• Strategy – a set of defined actions

A GUI for easy strategy creation is required.

The application must be platform-independent, so best technology recommendation is Java. Python is also acceptable. The application must contain an easy to use GUI.

Please give your pricing.

Feel free to make any suggestions, improvements or change requests – I am opened to negotiations.
