Category: Indicators / Trend / Channels / Levels

Product Description
PragmAlgo QuantStack Kalman Pro is an algorithmic technical analysis indicator developed for MetaTrader 5. It integrates real-time state estimation via a 2-State Adaptive Kalman Filter (Price Level and Underlying Velocity) with a multi-layer volatility compression engine (Bollinger & Keltner Squeeze), Kaufman Efficiency Ratio (KER) noise filtering, and macro trend alignment.
The indicator is engineered for discretionary traders who require objective velocity-driven entry triggers paired with an asymmetric risk-management structure (TP1, TP2, TP3) and non-repainting adaptive Stop Loss benchmarks.
Quantitative Transparency: Understanding the 86.4% Win Rate Mechanism
Mathematical Breakdown of the Win Rate:
In professional quantitative trading, a win rate above 80% warrants healthy scrutiny, as it is often associated with high-risk martingale tactics (trading without a Stop Loss) or excessive curve-fitting.
In QuantStack Kalman Pro, every trade operates with a strict, pre-defined Stop Loss. The 86.4% historical win rate is the result of an engineered asymmetric exit mechanism:
Total Win Rate (86.4%) = 28.1% (Full Target Hits to TP2 / TP3) + 58.3% (Capital Preserved at Protected Break-Even +0.10R)

How does this architecture function in live market conditions?
- High-Velocity Entry Filter (Kalman Velocity + KER): Entries only trigger when the estimated latent velocity vector is accelerating and the Kaufman Efficiency Ratio exceeds 0.35. As a result, in over 80% of generated signals, price momentum moves favorably over the first 1 to 3 bars.
- Capital Insurance at TP1 (+0.50R to +0.60R): As soon as price reaches the first target (+0.50R / +0.60R), the system automatically advances the Stop Loss to Protected Break-Even (+0.10R). This modest buffer covers broker spread and execution commissions.
- Trade Outcome Distribution:
- Full Target Hits (28.1% of trades): Price sustains institutional trend continuation, reaching extended targets TP2 (+1.80R to +2.00R) or TP3 (+3.50R to +4.50R).
- Protected Break-Even Exits (58.3% of trades): Price initiated favorably, secured the capital buffer at +0.10R, and subsequently retraced. In MT5 performance accounting and Python backtesting, a trade closed at +0.10R is recorded as a winning trade (PnL > 0). This prevents winning positions from devolving into full -1.00R losses.
- Full Stop Loss Hits (only 13.6% of trades): Only trades that fail immediately upon entry without reaching the +0.50R milestone incur a complete -1.00R loss.
- Why Drawdown Remains Low and Profit Factor Exceeds 2.0: Cascading drawdowns are mitigated because the 58.3% of trades that would represent -1.00R losses in conventional systems instead exit with a net positive or neutral balance (+0.10R).
Core Engine & Key Features
- 2-State Adaptive Kalman Filter: Models underlying price trajectory by separating genuine velocity from high-frequency market noise using an ATR-adjusted covariance matrix. Tracks hidden velocity to avoid deceptive range rotations.
- Bollinger & Keltner Volatility Squeeze: Detects market compression when Bollinger Bands (20, 2.0) contract inside Keltner Channels (20, 1.5 ATR). Highlights consolidation bars in neutral slate gray.
- Asymmetric Target Levels & Translucent Visual Framing: Automatically projects Entry, Initial Stop Loss (with a permanent dotted line for zero-curve-fitting auditability), and 3 Target Tiers with soft translucent boxes that do not obstruct candlestick patterns.
- QuantStack Matrix HUD Dashboard: Positioned in the upper-left corner of the chart, providing 17 live quantitative readings: Win Rate distribution breakdown (Target Hits vs BE Protected), Profit Factor, Kalman velocity, Shannon Signal-to-Noise Ratio (SNR), Z-Score deviation, and active preset status.
Historical Backtest Analysis & Built-In Presets
The indicator incorporates an automatic symbol and timeframe detection module (PRESET_AUTO_DETECT). The following performance metrics reflect historical backtest simulations conducted on broker tick data:
| Asset | Timeframe | Strategy Focus | Historical Win Rate | Profit Factor (PF) | Max Historical Drawdown | Testing Sample |
|---|---|---|---|---|---|---|
| Nasdaq 100 (NAS100) | H1 | Tech Index Momentum | 97.2% | 10.90 | 1.0 R | Historical Simulation |
| Bitcoin (BTCUSD) | M5 | Fast Crypto Scalp | 91.1% | 2.62 | 1.8 R | Historical Simulation |
| WTI Crude Oil | M15 | Commodities Scalp | 86.2% | 2.15 | 2.4 R | Historical Simulation |
| Gold (XAUUSD) | M15 | Metals Scalp | 85.4% | 1.81 | 4.4 R | Historical Simulation |
| S&P 500 (US500) | M15 | Index Intraday | 82.9% | 1.18 | 1.9 R | Historical Simulation |
| EURUSD | M15 | Forex Scalp | 82.4% | 1.15 | 2.5 R | Historical Simulation |
