| Product homepage | Product homepage — also hosted app. |
| Pricing and access | Apache-2.0 self-host via Docker Compose has no app purchase fee. Hosted SaaS at ai.quantdinger.com may have separate account/billing terms (hosted pricing not verified here). Live Jev filtering needs a TypeSafe key (JEV_API_KEY and related settings). Exchange, LLM, and infrastructure costs are separate. Checked 2026-09-20. |
| Jev evidence | backend_api_python/app/services/ai_decision_filter.py posts typed Choice questions to TypeSafe System One (JEV_BASE_URL default https://api.typesafe.ai/v1 + /systemone, model jev-latest) for pre-trade entry checks; code-owned policy maps answers to allow/block with fail-open on provider failure. |
| Disclosure | Independently curated listing; not an upstream submission or endorsement. AI-assisted source review of README and the decision-filter module. Live trading, hosted signup, and live TypeSafe calls were not run. Brand/commercial licensing for QuantDinger identity is separate from the Apache-2.0 backend license per upstream. Inclusion is not investment advice. |
| Maintainer | Open Byte Inc / OpenByteInc. Contributor affiliation/commercial relationships were not supplied. |
| Format | Self-hosted Docker Compose stack (Python 3.12 API/workers, web UI) plus optional multi-tenant SaaS path documented upstream. |
| Platform and availability | Source-built local/production Docker; hosted product at ai.quantdinger.com. Release stage: actively maintained public repo (11k+ stars at review). |
| Jev's role | Optional AI Decision Filter on regular live strategy / Quick Trade entry orders: six Choice checks (evidence quality, signal alignment, regime, account risk, execution quality, final pass/reject). Exits and emergency actions bypass AI. Grid/DCA/martingale runtimes excluded in this version. Without Jev, upstream may fall back to a configured LLM or fail-open allow with audit log. |
| Requirements | Docker Compose v2 for self-host; JEV_API_KEY (and optional JEV_MODEL / timeout / confidence) in System Settings → AI / LLM for the Jev path; exchange credentials for real trading. |
| License | Apache-2.0 for backend source; upstream notes brand/commercial terms separately. |
When to use
Use it when you want a full self-hosted trading research and execution stack and an inspectable typed pre-trade gate. Prefer Jev Trader for a small Bun experiment studying direction choices, or SmartMoney-Cub for a read-only journal/review harness without order routing.
How it works
When the filter is enabled, entry intents gather market/strategy/portfolio/budget state and call TypeSafe System One with the fixed JEV_QUESTIONS map. Application code interprets Choice outcomes and confidence (JEV_MIN_CONFIDENCE default 0.65), records an auditable timeline, and either allows the entry or blocks it. Provider failure fails open so AI outages cannot trap open positions; exits bypass the filter.
Get started
git clone https://github.com/OpenByteInc/QuantDinger.git
cd QuantDinger
git checkout 12c04eb2cdb8a9d08dc84502f5261ec3f1c56bf7
# follow upstream Docker Compose quick start in README
# configure JEV_API_KEY in System Settings → AI / LLM for the decision filter
Do not run live trading from this listing's review host. Enabling the filter sends order and portfolio evidence to TypeSafe when Jev is configured.
Examples and demos
- README section JEV-powered pre-trade decisions (flow diagram and settings).
- docs/agent for Agent Gateway / MCP notes.
- Upstream website/video links (vendor demos; not re-run here).
Limits and data handling
Pre-trade evidence leaves your deployment for TypeSafe when Jev is enabled. Fail-open behavior prioritizes position management over blocking on outages—confirm that matches your risk posture. This catalog does not validate strategy profitability, exchange integrations, or hosted billing. Trading involves financial risk.
Review and maintenance
Reviewed on 2026-09-20 at commit 12c04eb: Apache-2.0. AI-assisted review of README Jev section and ai_decision_filter.py. Docker bring-up, live exchanges, hosted SaaS, and live TypeSafe calls were not exercised.
