About This Project
Testing Ground Labs is an independent cybersecurity and IT testing organization (AMTSO member). In addition to security product evaluations and threat data collection, we apply the same rigorous validation methodology to other high-stakes, data-driven systems. This page presents a live model validation experiment: a rotation strategy developed and validated using Barchart market data — including historical OHLCV via Barchart OnDemand API (getHistory / getQuote) and Barchart for Excel (daily & intraday, 90+ technical indicators). The backtest engine replays daily signals against market data to produce NAV curves and performance metrics, while Alpaca Markets API provides real-time pricing for the live dashboard. This project is intended as a research and validation exercise, not as investment advice or asset management. Objective: validate whether this model achieves volatility ≤ VOO with XIRR ≈ QQQ, using fractional shares with minimal cash drag.
