MindTheSpread Forex Majors

Machine-learning signals for the major FX pairs, executed automatically in your MetaTrader 5. Direction, entry, stop-loss and take-profit are all model-driven, gated by a calibrated confidence score so only high-conviction setups ever trade. ATR-based sizing adapts to volatility, and returns are net of real spread — the cost is baked into the model itself.

What sets it apart is the validation. The model was fully trained and frozen on data through 2023, then traded forward on 2024–2026 — a true out-of-sample record with no look-ahead and no curve-fitting. No martingale, no grid, no averaging down. Just a disciplined statistical edge, copied straight to your account.

Our Models

Six Production Signal Models

Each model targets a single macro driver — JPY carry, CAD oil, GBP policy — validated with annual walk-forward cross-validation across five years of unseen data. All six are 5/5 years positive. Forex Majors is live on MQL5 now; the rest are rolling out as their own signals.

JPY Crosses

3.24 Sharpe across 7 yen pairs — all 5 folds positive, 12.6 trades per week

5/5 Years PositiveMinimal Risk

5/5 Years PositiveMinimal Risk

Trades six CHF pairs using a 3-class multiclass architecture with isotonic calibration and regime features. Driver: CHF safe-haven flows — the franc strengthens during risk-off episodes and weakens during risk-on periods, creating consistent cross-pair co-movement.

Technology

How Our Models Work

The technology is the product. We combine proven machine learning with rigorous financial engineering — no neural-network hype, just robust, interpretable models validated forward on unseen data. This is the engine behind every signal we publish.

Frozen-Model Forward Testing

The flagship model was trained and frozen on data through 2023, then traded forward on 2024–2026 it had never seen — 473 live-style trades with a hard boundary. This is forward performance, not a re-fitted backtest: the truest test of a real edge.

Calibrated Probability Engine

Raw model scores are mapped to true probabilities by an isotonic calibrator, so a 60% signal has historically won 60% of the time. Trading is gated on that calibrated confidence — the engine acts only when the odds are genuinely in its favour.

Gradient Boosting Ensemble

Our models use an ensemble of decision trees trained with gradient boosting — the same class of algorithms that wins ML competitions on tabular data. Robust, interpretable, and battle-tested.

50+ Engineered Features

Each prediction synthesizes over 50 carefully engineered features spanning momentum, volatility, market microstructure, and more — distilled from decades of quantitative finance research.

Hourly Signal Generation

Models process H1 (hourly) OHLC candles to generate directional predictions with a 48-hour horizon. Each signal includes a calibrated confidence score — only trades above the confidence threshold are executed.

Built-in Transaction Costs

Every prediction accounts for real spread costs. Our net return figures are after deducting actual bid-ask spreads — no inflated backtests, no hidden slippage.

Walk-Forward Validation

Every model is validated with 5-fold annual walk-forward cross-validation (2020–2024). Each fold trains on expanding history and tests on the next full year — exactly how the model runs in production.

Confidence-Gated Trading

Each prediction is scored by an isotonic calibrator that converts raw model output into a true probability. Only signals above the model's confidence threshold are traded — filtering out noise and low-conviction predictions.

ATR-Based Risk Management

Stop-losses and take-profits are set as multiples of ATR (Average True Range), so they automatically adapt to current market volatility. Tight in calm markets, wider in volatile ones.

Risk-First Architecture

ATR-based stop-losses and take-profits adapt to market volatility. Combined with per-symbol limits and circuit breakers, drawdown is structurally constrained.

Validation & Trust

Rigorous Validation. No Shortcuts.

In quantitative trading, trust is built through process. Every model passes a multi-stage validation pipeline designed to catch overfitting before it reaches your account.

11 Years of Training Data

Models are trained on data spanning 2015—2026, encompassing multiple market regimes: COVID crash, rate hike cycles, carry trade unwinds, and sustained low-volatility periods.

5-Fold Annual Walk-Forward CV

Performance is measured across 5 annual folds (2020–2024). Each fold trains on expanding history and tests on the next full year — exactly how the model runs in production.

True OOS Boundary (Major Forex)

The Major Forex model was fully trained and frozen on data through 2023, then evaluated on 2024–2026 data it had never seen — 473 trades on a hard out-of-sample period with no look-ahead.

Overfitting Risk Scoring

Each model receives a quantitative overfitting risk score (0.0—1.0). Models that show strong backtests but degrade on unseen data are permanently rejected from production.

Anti-Overfitting Checklist

Strict train/test time separation — no future data leakage
Strong regularization (L1 + L2) to prevent memorizing noise
Feature subsampling (80%) to reduce feature co-dependency
Minimum leaf samples enforced to avoid micro-fitting
Performance degrades monotonically when signal selectivity is relaxed
Net returns include real spread costs — no cost-free backtesting
Models that fail out-of-sample validation are permanently rejected

Transparency: Our Rejected Model

We believe in full transparency — including our failures. During development, one model (Elite CAD) showed exceptional backtest results (81% win rate, Sharpe 7.0) but completely failed out-of-sample validation:

Expected Win Rate
81% → 53.6%
Expected Sharpe
7.0 → 1.14
Overfitting Score
0.80 / 1.00

This model was permanently rejected from production. We share this because it demonstrates our validation pipeline works: impressive backtests alone don't earn a place in production. Only models that perform on unseen data make the cut.
