Identify Specific Requirements

Tradeslot worked with CTX to determine the key requirements of the platform and categories them into core vs custom features.

Build Custom Requirements

Tradeslot designed and managed the development of custom requirements:

  • integration with market leading environmental registry for seamless transfer of ownership
  • management of financial flows, including integration with major banks
  • online user registration form
  • look and feel changes to match CTX branding

Iterative Change Process

CTX was working to a timeline that required some development to move forward concurrently with design. Therefore, a just-in-time, iterative design process was adopted whereby Tradeslot worked closely with CTX on a day-to-day basis to ensure new design elements were incorporated. User Acceptance testing was adopted at appropriate milestones.

Configure System

Tradeslot configured the core system to meet CTX requirements including inventory view, allowing best control for trading multiple products on offer, including filters for vintages, associated industry accreditations and origin of credit automatic currency conversion –

EUR, GBP, USD and AUD as accepted currencies user options for flexibility of term of offer and whole/partial fill real-time index settings 24/7 trading hours.

Configure the Cloud

Tradeslot’s trading platform is based on Microsoft products and frameworks. Deploying the system to Microsoft’s Azure cloud was a natural progression. Cloud hosting ensures rapid scalability and reduced operating costs, allowing the team to focus on functionality, rather than hosting and hardware concerns.

Live Trading

After key configuration and custom requirements were released, CTX began to trade live in June 2010 – after only 3 months and below budget. Development of enhancement features continues.
