Trading Lab - Sell Project

TRADING LAB / RESEARCH WORKSPACE 0.3.0 Working English demo: https://trading-lab-passport-demo.piotr6436.chatgpt.site/ No login or exchange keys. Bring an OHLCV CSV, challenge assumptions, inspect individual trades and export evidence you can replay. THE STRATEGY PASSPORT Trading Lab turns a strategy idea into an inspectable research report: explicit inputs, causal EMA/ATR simulation, independent holdout, cost sensitivity, a complete trade ledger and portable JSON with SHA-256 checks and deterministic replay. Checksums demonstrate integrity and reproducibility, not external data authenticity or investment performance. NEW IN WORKSPACE 0.3.0 • Synthetic example or validated local CSV imports, 50–10,000 candles. • Equity and drawdown charts, filterable/paginated trades and exact-precision CSV exports for trades, equity and sensitivity. • Up to nine actual neighboring EMA simulations, each with its own holdout. Repeated holdout selection can overfit; this is exploratory research, not a strategy recommendation. • Compare up to three reports in a tab, with different datasets, capital, FX and holdout boundaries flagged. • JSON export/import/replay, modified-copy rejection, stale-report controls and a guided English tour. THE FULL ORIGINAL APPLICATION The separate Polish beta additionally includes public Kraken Spot candles for BTC/EUR, ETH/EUR and SOL/EUR, session-isolated saved reports, a SQLite PAPER portfolio, risk controls, deduplicated signals and a local rule-based analyst. No paid language-model calls are needed in the verified workflow. The public English workspace runs locally in the browser and has no accounts, database persistence or market-data API. RESEARCH MODEL Long-only EMA/ATR strategy; closed-candle signals and next-open fills; modeled commissions, spread, slippage, stops and price gaps. Independent chronological 70/30 holdout and actual strategy re-runs at 1x, 2x and 3x costs. Equity/ETF CSVs can be imported without native broker execution or corporate-action adjustment. TECHNICAL EVIDENCE Release 0.3.0 passes 25 automated application/unit/HTTP tests, TypeScript checking and the frontend production build. Development checks cover report replay/tamper detection, exports/imports, cost scenarios, comparisons and a 10,000-candle CSV. New full-app research panels were checked in the saved AI Studio preview. The unchanged research engine remains version 0.2.0. These are development checks, not an independent security audit or certification. INCLUDED ASSET Clean application source, dependency lockfile, setup and buyer documentation, automated tests and verification records. React, TypeScript, Vite, Node.js, Express and SQLite. Docker/Compose configuration is supplied; the Docker image has not been built or tested here. Built with AI assistance. Existing Apache-2.0 notices and third-party dependency licenses remain applicable; exclusive rights to all code are not represented. CURRENT STAGE Pre-revenue research software. No verified revenue, paying customers, traffic or investment profitability is claimed. LIVE execution is disabled; native stock-broker execution is not implemented. Accounts, billing, production backup/restore validation, independent security review, load testing and commercial validation remain to be completed. Synthetic demonstration returns are not live trading results. Potential fit: a developer, educator or fintech team seeking an existing research workflow and paper-trading foundation to develop for its audience. Acquisition enquiries and walkthrough requests are welcome. Final price, rights, transfer scope and support are subject to the owner's acceptance and diligence. Personal accounts, credentials, private databases, a domain and market-data redistribution rights are excluded unless separately agreed and verified. No guaranteed returns or valuation are offered.
