Rigorous calculation and disciplined risk management to protect your capital.

Silent Jack is a quant-grade validation tool for MetaTrader 4 / 5 Expert Advisors. Every prototype is stress-tested with 10,000-iteration Monte Carlo simulation
and a conservative backtest engine that deducts realistic spread, slippage, commission and swap — so the numbers you see reflect what you would actually face in
live conditions.

The "⚔ Judge" verdict turns every EA into a clear, defensible reading:
- Go (S/A): ruin probability under 5%, positive expectancy
- Caution (B/C): ruin probability 5–20%, marginal edge
- Reject (D): ruin probability over 20% or negative expectancy

Only the strategies that survive cost stress, time-period stress, and leverage stress get a green light. The point is simple: protect your capital first, then pursue returns.
