Baseline Capital Protection (State 0):
Base risk per trade ($R_0$) is strictly capped at $0.25\%$ of core account equity. If 3 consecutive losses occur ($-0.75\%$ daily drawdown), a mandatory 45-minute cooldown triggers; if daily drawdown hits $-1.25\%$, trading halts for the session.
Profit-Buffer Escalation (States 1 to 3):
Whenever a scalp closes in profit, 50% of the net realized gain is permanently locked into the daily equity floor, while the remaining 50% is allocated to an Active Scaling Buffer ($B_{\text{scale}}$).
For the next A+ setup within the same liquidity session, total risk is dynamically calculated solely from the baseline plus the active buffer.
This creates convex equity growth during clean institutional sessions (allowing position sizes to scale $2\times$ to $4\times$ solely using accumulated market gains) while mathematically guaranteeing that a reversal on the final trade of a winning streak can never put the session into a net loss.

Architectural Highlights of the MQL5 Implementation
Object-Oriented Execution & State Tracking: Built on the MQL5 Standard Library (CTrade, CPositionInfo, CSymbolInfo) with asynchronous-ready filling mode detection (ORDER_FILLING_FOK / ORDER_FILLING_IOC) and strict broker lot-step normalization (SYMBOL_VOLUME_STEP).
Layer 1 (Rolling Hurst & Intraday VWAP Engine): Calculates the rescaled range ($R/S$) Hurst Exponent over M15 log returns to switch dynamically between Mean-Reversion Fade Mode ($\text{Hurst} \lt 0.45$), Random Walk Stand-Down ($0.45 \le \text{Hurst} \le 0.55$), and Momentum Continuation Mode ($\text{Hurst} \gt 0.55$).
Layer 2 (Triangular Basis Z-Score with Auto-Fallback): Computes real-time synthetic log-spread dislocations across EURUSD, EURGBP, and GBPUSD using a rolling circular buffer. When deployed on single-asset symbols like XAUUSD or in single-pair tests where cross pairs are disabled, it automatically falls back to an internal tick-velocity Z-score.
Layer 3 & 4 (M15 FVG + M5 Liquidity Sweep + Sub-M1 CVD & L2 Book Imbalance): Combines CopyTicks (with a Lee-Ready tick-direction fallback when broker tick flags are absent) and MarketBookGet Level-2 DOM depth weighting. If your ECN feed or Strategy Tester does not broadcast Level-2 depth, the EA seamlessly synthesizes book pressure from high-frequency tick delta velocity.
Layer 5 (House-Money Compounding, 3-Tranche Exits & Kalman Trail): Tracks closed net PnL (including ECN commissions and swaps) inside OnTradeTransaction(). Every profitable scalp locks 50% of net profit into the daily equity floor and channels 50% into the Active Scaling Buffer, while managing open trades with a 180-second velocity time-stop, two partial scale-outs (50% at $1.2R$ and 30% at $2.2R$/VWAP), and a 1D Kalman Filter trailing stop on the final 20% runner.

Deployment & Strategy Tester Notes
Broker Symbol Suffixes: If your Raw ECN account appends a suffix (such as .r, .a, or .pro), update InpCrossPairA and InpCrossPairB in the EA inputs to match (e.g., EURGBP.r and GBPUSD.r).
MT5 Strategy Tester Mode: Always run backtests in "Every tick based on real ticks" mode. Because CopyTicks() evaluates sub-minute bid/ask delta absorption inside VerifyOrderFlowTrigger(), standard OHLC-only modeling will not generate realistic Cumulative Volume Delta divergences.
Would you like to add a custom on-chart MQL5 telemetry HUD (CChartObjectLabel panel) to visualize the live Hurst Exponent, Synthetic Basis Z-Score, Book Imbalance Ratio ($BIR$), and your locked vs. active House-Money buffer in real time?

What Was Added for the Live HUD
Zero-Lag Telemetry Caching: Live metrics (g_liveBasisZScore, g_liveBIR, g_liveCVDMomentum, g_liveCVR, and g_lastSweepStatus) are continuously sampled and cached so the HUD reflects sub-second ECN order-flow state even when no trade is open.
Color-Coded Gate Diagnostics: Each of the 5 QLM-7 layers turns Lime (clrLime) when its quantitative threshold is armed, Orange/Gold (clrGold) in neutral standby, and Crimson (clrTomato) when a hard veto is active (such as Random Walk Hurst $0.45 \le H \le 0.55$, high spread-to-ATR cost $CVR > 0.18$, or a 3-loss cooldown).
Strategy Tester Visual Mode Compatibility: Automatically throttles chart redraws (ChartRedraw) in backtests unless Visual Mode is enabled, preserving maximum tick-processing speed during multi-year optimizations.
