TradingBox Pro

A capable developer can build a useful backtester + basic live bot replacement (using existing open-source projects), but reproducing a polished commercial trading product with paid data, broker relationships, support and operational robustness is not realistic for one person.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All TradingBox Pro alternatives, with the arithmetic →

What a replacement has to do

  • Ingest market data, run strategies/backtests, place orders via broker APIs, show status and simple metrics in a dashboard.

What it still won’t have

  • polished commercial UI/UX and onboarding
  • paid market data feeds and latency-optimized connectivity
  • existing broker partnerships and tested order-routing at scale
  • customer support and SLAs
  • security audits, compliance, and operational monitoring

What remains hard

  • Product polish and ongoing maintenance

Runnable build prompt

Not run yet
Build a minimal self-hosted trading platform using Python (FastAPI) + Postgres + Docker. Core features: ingest OHLCV historical CSV and realtime quotes (WebSocket/REST), normalize/store data in Postgres, implement a rule-based backtester that computes P&L and drawdown, implement a simple live execution adapter for a generic broker REST API (place/cancel orders, track fills), minimal React dashboard to list strategies, start/stop live runs, and display recent orders and equity curve. Out of scope: paid market data integrations, exchange-specific low-latency matching, user multi-tenancy, and advanced risk management. Include logging, error handling, unit tests for data ingestion/backtester and CI pipeline, and Docker compose deployment instructions.

How the score was reached

  • An open-source build was found+5
  • 3 cited sources+3
  • Evidence score60

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
