Butterfly Optimization Algorithm (BOA), proposed in 2019 by Arora and Singh, models movement using a fragrance term f = cΒ·I^a and a switch p between global and local search. Fitness is mapped to stimulus intensity I, then converted to fragrance via the power law, with a increasing toward 1 over epochs to shift from broad search to stronger exploitation.
Implementation review found a critical issue in the paperβs update equations. Using x_new = x + (rΒ²Β·g* - x)Β·f biases steps toward rΒ²Β·g*, which tends to pull the population toward the origin and only looks correct when the optimum is at 0.
A corrected form preserves components but fixes geometry: x_new = x + rΒ²Β·(g* - x)Β·f, and locally x_new = x + rΒ²Β·(x_j - x_k)Β·f. Testing should include optima away from the origin to catch this class of error.

| 2 |  AurumNeuro Vanguard is an Expert Advisor focused on XAUUSD, built around a hybrid neural risk design and a Unified Market Dynamics Engine. Signal generation combines causal price analysis, online neural learning, and ATR-based risk controls rather than relying only on standard indicators.
The UMDE layer evaluates direction using price velocity, entropy, and Causal Price Dynamics to filter weaker conditions. A 5-12-3 neural network trains online on prior bar data and is used for directional confirmation plus dynamic TP/SL guidance.
Risk handling supports fixed lot or risk-percent sizing with auto sizing based on SL distance, commission, and tick value. Trade management includes ATR trailing with optional aggressive behavior, volatility-aware stop widening, RR-based profit hard close, and early loss exits when neural confidence drops. Execution filters include ...

| 3 |  TQNet targets multivariate market forecasting by combining fast reaction to current conditions with a learned βglobal memoryβ of stable cross-asset relationships. Instead of building attention queries from raw prices, it uses trainable vectors that shift cyclically over time, while keys/values still come from the live input window. This balances persistent structure (seasonality, recurring liquidity cycles) with local shocks and noise.
Architecturally, it stays lightweight: one multi-head attention block plus a shallow MLP with residual connections, then a linear projection to any forecast horizon. RevIN normalization is used to handle distribution shifts common in finance, keeping the model focused on patterns rather than changing scale/volatility.
The article also outlines an MQL5-oriented implementation path and positions TQNet as a practical a...

| 4 |  MT5 historical demonstration on XAUUSD (RoboForex-ECN), 1 Mayβ8 Sep 2026, using 100% real ticks. Test settings: USD 10,000 deposit, 1:100 leverage, fixed 0.01 lot, default parameters (v0.11 defaults match the demonstrated set; trading logic unchanged vs v0.10). Result is optimized history, not a forward test.
Performance summary: 220 trades, net profit USD 1,293.99, profit factor 1.67, max equity drawdown USD 203.00 (1.91%), win rate 28.64%. Both long and short sides were net positive. Low hit rate included 13 consecutive losses, with expectancy driven by larger winners.
Inputs: brick size 6.0 (price units), momentum 8, threshold 5.0, TP 10 bricks, SL 2 bricks, max hold 1440 min, cooldown 3 bricks, max spread/brick 0.35, Magic 26091043.
Operational notes: validate in Strategy Tester. Brick size is price units, not points. Virtual SL/TP require terminal uptim...

| 5 |  Work continued on hardening an automated MT5 optimization pipeline rather than adding trading logic. Core library and strategy-specific project code were further separated, so new ideas can be tested by changing project parameters without editing the shared library.
Optimization tasks now support time limits to cap end-to-end runtime and stop early once enough strong candidates exist. The optimization EA UI was expanded to show stage, symbol, timeframe, elapsed/remaining time, and overall progress.
CConsoleDialog was fixed to avoid duplicated windows after restarts by correcting OnDeinit cleanup. Chart elements behind the UI were disabled to avoid font rendering issues and remove the need for window minimization, requiring small local copies of standard library dialog classes.
Next focus: running multiple instances of the final multi-currency EA across dif...

| 6 |  Portfolio eigenvalues describe how total variance is split across independent risk factors, but raw spectra donβt clearly indicate whether diversification is real or just cosmetic. This workflow turns the eigenvalue proportions into a single diversification score using spectral entropy (Shannon entropy normalized to [0,1]): high values mean variance is evenly distributed; low values indicate one dominant driver.
A reusable MQL5 script computes the covariance matrix, extracts and sorts eigenvalues safely (ArraySort over unreliable vector.Sort), converts them to variance shares, then outputs H_norm, dominant-factor percentage, an ASCII bar chart, and a thresholded concentration verdict for side-by-side portfolio comparison.
A key takeaway: diversification is governed by covariance structure, not instrument labels. Adding an uncorrelated but high-vola...

| 7 |  Multi-chart EAs often act as if they are the only process in the account. The broker enforces margin, margin level, and liquidation at account scope, so individually well-sized trades can still combine into a full drawdown.
A shared PortfolioRisk.mqh moves portfolio measurement out of any single EA. It supports account-wide scope or a magic-number filter, scans positions plus pending orders, and builds currency-leg exposure without parsing symbol names.
Before opening a trade, CanOpenPosition() evaluates six limits on the βwould beβ state: total trades, per-symbol count, distinct symbols, margin use, floating loss, and per-currency net exposure. Pearson correlation is noted but intentionally excluded; currency decomposition is deterministic, history-free, and consistent across EAs.

| 8 |  This MQL5 script turns closed deal history into trade-level analytics that avoid the common win-rate trap. Deals are grouped by position into a single record per round trip, with explicit βdefinedβ flags so missing metrics never masquerade as zeros.
The core metric, Trade Quality Score, uses expectancy but substitutes the Wilson lower bound for win rate to penalize small samples. The conservative expectancy is normalized by average loss as a risk proxy, yielding a dimensionless score comparable across symbols and account sizes.
Architecture is modular: history reader, optional hour-of-day session filter (midnight-safe), pure calculator, and a CCanvas dashboard plus Experts-tab report. A dedicated test script validates pip conversion, edge cases, Wilson math, thresholds, and session boundaries with synthetic trades.

| 9 |  A new MQL5 signal class, CSignalIsotonicPNN, implements a two-stage confidence model for oscillator-based entries. Seven RSI/Stochastic plus price-context interpretations output a bounded directional score in [0,1], with 0.5 as neutral.
Isotonic regression calibrates the score into an ordered probability using a rolling calibration window and forecast horizon, with safeguards against lookahead. An optional PNN then blends a posterior based on similarity to historical bullish/bearish states, controlled by PNNSamples, PNNSigma, and PNNWeight.
The design keeps each mode independently testable and separates ranking quality from calibration. Invalid inputs and degenerate computations return 0.5 to avoid accidental directional bias.

| 10 |  PulseStrike is a tick-driven scalper built around burst detection, not candle close. It maintains a rolling baseline over a short window (default 4s) and treats a move as tradeable only when it is a statistical outlier versus that baseline (z-score, default 3.0). This replaced a fixed ATR-fraction trigger that over-traded normal tick noise.
Two execution modes are supported: momentum (with the burst) and reversion (against it). Symbol fit is not assumed; both modes should be tested.
Entries are gated by spread-aware TP sizing, ATR-scaled SL/TP, a max hold-time force close, plus daily trade and daily loss caps. Single-position operation is used to behave correctly on netting accounts, cycling trades with tick-level checks and a short cooldown.

| 11 |  EMTOrdersUtility.mq5 implements an on-chart trade monitor that replaces terminal scrolling with a symbol grid. Each symbol is rendered as a button plus up to three stacked label lines, refreshed via EventSetTimer at a user-defined interval.
Symbols can be loaded from Market Watch or a manual CSV list, capped by InpMaxSymbols. Display names can be abbreviated by stripping common broker suffixes, and button width can be fixed or auto-sized based on the longest label.
Runtime updates aggregate positions per symbol, split by BUY and SELL, with swap included in P&L. Pending orders are counted separately and can be highlighted via border settings. Button background reflects net P&L state (profit, loss, flat), with a selected-symbol color override.
Version notes mention alphabetical symbol ordering and removal of the hide/show toggle.

| 12 |  Range volatility can be measured beyond ADR% by using an empirical percentile rank. The metric compares the current periodβs range so far to the full ranges of the last N completed periods, reporting what percentage were smaller. This avoids mean-based distortion in instruments with occasional spike sessions.
Readings at or below the compression threshold (default 20) flag an unusually quiet period; readings at or above the expansion threshold (default 80) indicate a session already larger than most historical peers. A 12% value means the current range is smaller than 88% of the last 100 periods.
Key inputs include range timeframe (D1 by default), lookback (100), thresholds (20/80), and update mode (per bar or per tick). The panel includes a 0β100 gauge, uses only chart objects, and does not place or manage orders.

| 13 |  Colliding Bodies Optimization (CBO, 2014) is a population metaheuristic where candidate solutions are ranked, assigned normalized masses from inverse objective values, then split into stationary (best half) and moving (worst half) sets.
Each moving body pairs by rank with a stationary body. Velocities are computed from position differences, then updated with a restitution coefficient epsilon that decreases linearly from 1 to 0 across iterations to shift from broad search to refinement.
Enhanced CBO (ECBO) adds a Colliding Memory archive to reinsert elite solutions and an optional low-probability coordinate reset step to reduce stagnation. Per-iteration cost is dominated by sorting: O(n log n).

Violations can void the account even when platform limits are not hit.
This library provides a reusable guard that compiles into any EA. It evaluates eight rules from one frozen account snapshot per pass and emits at most one directive, avoiding multiple reactions to the same event. It does not trade and can work alongside any EA, manual trading, or copied signals.
Archive contents: 24 .mqh headers, a facade class (CPropRulebook), and a demo EA (PropFirmDefense.mq5) with an on-chart panel. State is persisted across restarts, including trailing-floor anchoring and consumed budgets. Optional terminal Algo Trading switching ...

| 15 |  Update on the MT5 replay/simulation series focuses on why the system works: custom events are generated by indicators, routed through MetaTrader 5, and delivered to all apps on a chart via OnChartEvent.
Chart Trade, the Expert Advisor, the Position indicator, and Mouse Study remain decoupled. None of them require direct references to each other. Events are broadcast, and only modules implementing the corresponding handler react; others ignore them.
Two event categories are used: EA-originated update events after trade server replies, and UI-driven events from MT5/indicators (mouse move, click, ESC). Virtual SL/TP dragging is confirmed or canceled by subsequent events.
A requested extension is EA-controlled pause/play for the replay service. Since events are chart-scoped, the service must be reached via its control indicator by adding a custom even...

| 16 |  Multi-timeframe Malaysian SNR can be automated without relying on lagging indicators. MSNR KeyLevels MultiTF scans closed candles and maintains four level types: A (bullish then bearish, close of bullish candle), V (bearish then bullish, close of bearish candle), plus SBR and RBS when a level is closed through and flips.
Levels are tracked from creation. A close through refreshes and changes the type. A touch without a break marks the level as tested and, by default, removes it so the chart keeps only untested zones. The unfinished candle is ignored to avoid repaint-style behavior.
A chart HUD controls six timeframes at once, with per-timeframe level counts and instant toggling. Line style encodes timeframe, color encodes type, and labels include timeframe and price. The design avoids tick-by-tick recalculation and rebuilds cleanly after timeframe ch...

| 17 |  MQL5 class lifetime can differ sharply between implicit instances and pointer-managed instances.
Declaring a class variable lets the compiler decide constructor/destructor timing. In an indicator, the constructor may run before OnInit and the destructor after OnDeinit, which reduces control over chart objects.
Switching to a pointer and using new/delete moves lifecycle control into OnInit/OnDeinit. Logged output confirms constructor runs after the OnInit log line and destructor runs before the OnDeinit log line.
In scripts, local scope adds another constraint: passing class instances into routines requires pass-by-reference, otherwise compilation fails. This raises API design questions around mutability and unintended state changes.

| 18 |  Index CFD backtests can look stable while quietly bleeding overnight financing. In MT5, swap modeling is hard to audit: brokers use POINTS (fixed points/night) or INTEREST (annual % of price), the optimizer cache doesnβt store swap per pass, and the tester applies todayβs swap snapshot across the entire history.
A read-only MT5 script converts each symbolβs swap into an annualized % of position notional, making financing comparable across brokers and instruments. Real scans showed the same indices costing roughly -4.7% to -9.9% per year long, while shorts could be credited or charged depending on broker and symbol.
Deal-level analysis matters: in a multi-year swing test, swap consumed 44% of gross profit overall, and fully erased one indexβs gains. Practical workflow: re-run best optimizer passes as single tests, inspect deals per symbol, distrust ...

| 19 |  Reinforcement learning in trading remains unstable due to non-stationary regimes, sparse rewards, high-dimensional states, and costly exploration. Classical DQN can overfit to historical volatility, then fail when markets shift, with retraining downtime not viable.
A hybrid stack is proposed: quantum state encoding + Double DQN + an LLM adapted via MIT SEAL. Quantum circuits compress 6 market inputs into 6 distribution statistics; entropy is used as a regime-instability signal.
The LLM produces direction and confidence; SEAL keeps only top-reward forecasts for periodic fine-tuning, asynchronously. A minimal Q-table agent then filters signals with 27 discretized states and 3 actions: USE, SKIP, REDUCE, enabling low-risk integration into existing trading logic.

| 20 |  Replay/simulation series update: position visualization is being moved out of Expert Advisors into a dedicated indicator, with a strict separation between server linkage and chart rendering.
A stability fix is added to EA initialization: on restart, stale position objects are purged to avoid mismatches after crashes or configuration changes such as contract type switches.
Interaction is implemented via custom chart events. OnTradeTransaction in the EA emits EventChartCustom on volume changes, SL/TP updates, and closures (NETTING), while initial position creation still triggers indicator placement.
The position indicator receives and filters these events in OnChartEvent, updating or deleting HLINE objects based on current position state, keeping logic testable and minimizing duplicated code across EAs.
