Since 2021, JSI has completed 270+ trading-software builds and custom enhancements, including ATAS indicators, trading bots, backtesting modules, execution and risk-management tools, market-data utilities, and licensing integrations for these solutions.
ATAS. Supporting web integrations may also be developed when required for the project.
Project-dependent. An estimated timeline is provided after the project scope and technical requirements have been reviewed.
Post-delivery support is available within the agreed project scope. Additional features, future ATAS platform adaptations, and ongoing maintenance are discussed separately.
Project-based. Pricing is provided after the requested logic, functionality, and scope have been reviewed.
JSI develops and provides custom indicators and educational materials for ATAS, specializing in order flow and market analysis tools.

The JSI Chart Notes indicator lets you display your own text directly inside the ATAS chart workspace.

A powerful search engine for your footprint chart. Instead of searching manually, build your own rules from over 15 filters, and let the indicator instantly highlight the exact candles that match your specific criteria.

The indicator helps traders analyze compact range areas and range-impulse behavior using user-defined order-flow conditions.

A pattern-recognition indicator that detects market triangles (symmetrical, ascending, descending, expanding) and overlays cluster volume and delta filters inside each shape. Go beyond geometry — analyze order flow context inside patterns.

A harmonic pattern detector enhanced with order flow filters. Combine classic geometry with real cluster and delta data for deeper analysis of potential reversals.

A focused tool for detecting rebound levels with optional delta filters. Helps traders mark structured bounce areas instead of relying on intuition.

JSI Trade Mirror is a behavioral support widget that keeps discipline metrics, personal notes, and reminder panels visible on the chart — helping traders monitor overtrading, revenge entries, and loss streaks in real time.

Trendline indicator that detects two- and three-touch price-reaction structures. Apply delta and volume thresholds to highlight lines backed by meaningful order-flow activity.

The first AI-powered course for ATAS traders to create custom indicators without coding. Using developer-designed prompts and templates, you’ll transform trading ideas into working indicators in minutes. A practical entry point into AI-for-ATAS.
