How It Works

From market data to actionable signals

Our quantitative pipeline processes market data every session to surface the setups that clear each strategy's entry criteria.

01

Scan

Five strategy engines continuously scan thousands of US equities and ETFs across multiple timeframes, analyzing price action, volume, fundamentals, and volatility regimes.

02

Analyze

Candidate setups are cross-referenced against fundamental data and the prevailing volatility regime. Each signal is scored for confidence and assigned risk parameters.

03

Signal

Actionable trade signals with precise entry, target, and stop-loss levels are delivered in real time. Every signal includes a risk/reward ratio and supporting factor analysis.

Platform Features

Everything you need to trade with edge

Built by engineers and quantitative researchers, with input from an advisory board of institutional fund managers. Every feature is designed to give self-directed investors a professional toolkit.

Multi-Strategy Signals

Five independent engines — trend, momentum, mean reversion, volatility, and fundamental — cross-validated for higher conviction.

Backtesting & Validation

A backtesting engine with walk-forward optimization and out-of-sample validation, so strategies are tested on data they were not fit on.

Risk Management

Hard drawdown stops, dynamic position sizing, correlation monitoring, and portfolio-level risk budgets enforced at the platform level.

Our Validation Approach

No performance claims until the results are real

Sapphire is in a paper-trading validation period. We are not publishing return, win-rate, or risk statistics until that period is complete and the results have been reviewed. Below is how we get there.

Backtesting

Each strategy is evaluated against historical market data using walk-forward optimization, so parameters are fit on one period and tested on the next.

Out-of-sample validation

Strategies are re-tested on data held back from the fitting process. A strategy that only performs in-sample does not advance.

Paper trading

Validated strategies run against live market data in a paper-trading account at Alpaca, with no client capital at risk.

Audited reporting

Every signal and outcome is timestamped and archived. Performance will be published only after the paper-trading period is complete and independently reviewed.

Backtested and simulated results, when published, will differ from live trading due to slippage, fees, and market conditions. Past performance, whether actual or simulated, is not indicative of future results.

Strategy Engines

Five independent alpha sources

Each strategy implements a distinct market thesis. The goal of running uncorrelated signal sources side by side is to avoid depending on any single market regime.

Trend Follower

Captures sustained directional moves using adaptive moving averages, ADX filters, and volume-confirmed breakouts. Designed for trending markets.

Mean Reversion Engine

Volatility Regime

Fundamental Screen

A weighted scoring screen over valuation, short interest, insider activity, and earnings-quality proxies to surface fundamentally attractive setups.
