TS-SystemChecker is a professional trading-system evaluation tool designed to help developers determine whether a strategy is still behaving within its historical expectations — or whether it has begun to break down.

Built by George Pruitt, TS-SystemChecker combines two powerful tools in one application:

1. Incubation Analysis
2. Full Monte Carlo Analysis



The Incubation tool allows you to compare a trading system’s real-time, out-of-sample performance against its historical baseline. Instead of relying on gut feel, a few recent trades, or a simple equity curve, TS-SystemChecker measures how the system is actually performing after its “go-live” date.

It tracks important diagnostics such as:

• Return Attainment
• Normalized RMSE
• Path Wander Ratio
• Drawdown Stress
• Monthly Equity Correlation
• Hypothetical, Actual, and Combined Drawdown
• Incubation Readiness Score

These metrics help answer the question every system developer eventually faces:

Is this system still operating within historical boundaries, or is something changing?

The Full Monte Carlo tool gives you a broader view of forward-looking risk and reward by reshuffling the trade history and simulating thousands of possible future equity paths. This gives you a better sense of the journey ahead — not just the final destination.

TS-SystemChecker includes charts such as:

• Baseline Projection
• Forward Envelope
• Monte Carlo Journey Chart
• Destination Histogram
• Efficiency Cloud
• Risk-of-Ruin Scaling Table

These visual tools help you evaluate whether a system’s current performance, drawdowns, volatility, and profit path are reasonable when compared to what the system has historically produced.

TS-SystemChecker was created for traders, system developers, and researchers who want a practical way to monitor trading systems after development. It is especially useful for those who keep systems “on the shelf” and want to determine whether enough out-of-sample data has accumulated to justify further attention.

This is not a black-box trading system. It does not generate buy and sell signals. Instead, it helps you evaluate the systems you already have.

TS-SystemChecker helps you answer three critical questions:

Is the system healthy?

Is the drawdown historically acceptable?

Is the system ready for further consideration, scaling, or retirement?

For anyone serious about algorithmic trading system development, TS-SystemChecker provides a structured way to move beyond hope, fear, and guesswork.
