Standard moving averages miss a key intraday detail in MT5: they ignore tick volume, so a high-impact news candle can distort βfair valueβ and trick EAs into pullbacks far from where real liquidity concentrated.
This article implements a daily-reset VWAP with volume-weighted deviation bands, using typical price (HLC/3) and tick volume. It enforces closed-bar calculations (shift=1) and a hard reset at 00:00 broker time, treating VWAP as a liquidity anchor rather than fixed support/resistance.
The core is a reusable VWAP_Engine.mqh class: midnight is found via MqlDateTime (robust to missing bars), rates are loaded with CopyRates and ArraySetAsSeries, and a two-pass loop computes VWAP then volume-weighted variance with zero-volume safeguards.
The same engine powers both an indicator (fast updates via prev_calculated) and a pullback EA (new-bar gate, CTrade, mean-...

Breakeven and trailing stops are dynamic, so an MT5 terminal restart can break trade management even when the position stays open. The missing pieces are not just virtual SL/TP levels, but the decision history: whether breakeven already fired, whether trailing is active, and the last price that advanced the trail.
This part extends the recovery architecture by persisting that state in SQLite. Breakeven becomes a one-time transition tracked by a breakevenActivated flag, saved immediately when the virtual stop is upgraded.
Trailing is treated as an evolving workflow. A lastTrailPrice marker plus step/distance rules prevents repeated updates and lets the EA resume trailing from the exact progression point after restart.

Multi-timeframe EAs can require hundreds of indicator handles when monitoring many symbols and timeframes. Eager creation in OnInit() forces the terminal to connect feeds, sync history, allocate buffers, and register every handle upfront, which increases startup latency and wastes memory on rarely used combinations.
A lazy-loading handle manager reduces this cost by creating handles only when requested, sharing identical configurations via reference counting, and centralizing cleanup through a single FlushAll() in OnDeinit().
The cache uses a composite key: symbol + EnumToString(timeframe) + integer indicator type + serialized parameters. Parameters should be serialized with IntegerToString() and fixed DoubleToString() to avoid locale-dependent keys. Release decrements ref counts and calls IndicatorRelease() only at zero, preventing orphaned handles across relo...

Premium Discount Range Mapper is an educational indicator for MT5 that maps a user-defined price range into Premium, Equilibrium, and Discount zones to support market context analysis.
The active range can be set manually or calculated automatically from a lookback period. With automatic mode, leaving Range High and Range Low at 0 makes the tool use the highest high and lowest low in the selected window. With manual mode, custom inputs define the zone boundaries.
Output includes Range High/Low, the 50% Equilibrium level, and optional 25% and 75% reference levels. The zones are visual references only and are not trade signals.
The indicator does not place orders, does not generate buy/sell calls, does not forecast direction, and does not guarantee outcomes.

This article extends MT5 money management beyond linear lot scaling by adding a regime-aware circuit breaker for tail-risk, high-volatility periods. The core idea is to size positions based on how close current conditions are to historical liquidity failures, not just per-trade risk percentages.

Trading losses are usually tied to risk drift: daily limits get exceeded after a losing trade, drawdowns accumulate unchecked, and predefined rules are ignored at execution time.
A MetaTrader 5 risk layer can remove that failure mode. An include-based EnhancedRiskManager.mqh centers on CEnhancedRiskManager, enforcing per-trade risk, daily drawdown, and total drawdown with conservative/moderate/aggressive presets, plus adaptive balance/equity drawdown measurement and state persistence via terminal globals.
Stress test: an aggressive martingale grid (1.5x, 200-point steps, up to 8 positions, no SL). Baseline lifespan averaged 3.2 days with 100% drawdown. With limits (5% daily, 10% total, 2% per trade), the 9-year run stayed profitable: max daily DD 4.8%, max total DD 9.7%, total return 127%, using trade blocking, forced close near limits, and profit trailing.

MT5 restarts clear an EAβs in-memory state, resetting risk counters, regime flags, optimization schedules, and runtime toggles. Production systems need deterministic continuity, not a fresh start after every terminal interruption.
The article builds a native MQL5 persistence layer using a readable key=value flat file in MQL5/Files/, avoiding SQLite, terminal GlobalVariables, and external dependencies. Flat files stay inspectable and per-EA, while GlobalVariables are shared, double-only, and opaque.
The design is modular: a typed value wrapper with safe type inference, a strict line parser (whitespace, comments, key validation), a serializer for consistent formatting, and a CHashMap-backed cache for O(1) reads. Writes rewrite the small file (O(n)), trading simplicity for reliability and easy integration into existing EAs.

Four intrabar entropy estimatorsβShannon, Plug-In (w-grams), LempelβZiv complexity, and Kontoyiannis entropy rateβare ported from a NumPy/Numba Python reference to practical MQL5 code for MetaTrader 5.
The design works around MT5 constraints: intrabar ticks come only from the broker-limited CopyTicksRange() cache, so older bars are marked with a sentinel (ENT_EMPTY). Bars also require a minimum tick count to avoid meaningless estimates.
Tick directions are encoded from bid changes into a compact ternary uchar stream {0,1,2}. Sequential estimators avoid missing Python primitives by using a base-3 hash for overlapping w-gram counts and a bounded look-back window to cap Kontoyiannisβ O(nΒ²) search.

Multi-symbol risk often gets understated when per-trade sizing is evaluated in isolation. During macro releases, EURUSD, GBPUSD, and XAUUSD can move in the same direction on the same driver, turning three 1% allocations into a fast 3% portfolio hit.
Single-instrument volatility is useful but incomplete for portfolios. The missing component is co-movement, captured by the covariance matrix. Portfolio variance is wα΅Ξ£w, not the sum of individual variances; cross terms dominate when correlations rise.
A practical MQL5 implementation centers on PortfolioRiskAnalyzer.mq5: fetch multi-symbol closes, compute log returns, assemble a returns matrix, then compute Ξ£ via matrix.Cov() and risk via MatMul(). Recent MT5 builds back these operations with OpenBLAS for scalable linear algebra.

Many EAs generate signals but lack an authorization layer between detection and execution. That gap causes premature entries, late trades after expiry, and interference from other EAs or manual orders.
A discipline model can formalize setup lifecycle states: NO_SETUP, SETUP_FORMING, SETUP_CONFIRMED, SETUP_ACTIVE, SETUP_EXPIRED. Execution becomes state-driven, not pattern-driven.
Trade authorization rules can be centralized in a CanTrade() gate: confirmation, expiry window, freshness, session filter, and a global lock.
Enforcement is handled separately via CDisciplineGuardian: alert, auto-close, or auto-close plus terminal-wide lock. Visibility is provided by CDisciplinePanel with on-chart status for state, permission, expiry, freshness, session, and guardian mode.
Integration into an EA routes every order through the layer before any execution call.

Transformers bottleneck on market history because attention scales as O(NΒ²), making multi-thousand-bar context too slow for latency-sensitive trading. Mamba replaces attention with Selective State Space Models, delivering O(N) sequence processing and effectively unbounded context.
Its core gain is selective memory: SSM dynamics adapt to the input so the model reinforces regime shifts (volatility spikes, news-like shocks) while damping routine noise. The block design combines local convolution for short-term structure, a selective SSM for long memory, gating for controlled information flow, plus stability-focused initialization (HiPPO) and training with AdamW. Patching further reduces compute by turning bar groups into meaningful tokens.

Quasimodo reversals are hard to trade manually because the βshapeβ is subjective and entries often feel late. This article turns the QM idea into a rule-based MT5 EA that detects the pattern, confirms it with a break of structure, then enters only after a retrace to the QM (left-shoulder) level.
Detection is built on confirmed swing pivots: a pivot is accepted only after N bars close on both sides, then compressed into an alternating zig-zag by merging consecutive same-type pivots into the most extreme point. A prior-trend filter validates there was a real trend before the reversal.
Execution is fully structured: entry at the QM line, invalidation beyond the head, target at the broken leg level, with optional close-back-through confirmation, reward/risk filtering, risk-based lot sizing, trailing/TP modes, trade-record syncing after restarts, and vi...

Classification is rule-based with priority ordering: Stressed, Informed, Trending, Noisy, MeanβReverting, Normal.

John F. Ehlers treats price as a signal with frequency components, not a chart pattern. The focus is a practical MQL5 DSP library that ports published coefficients and formulas, with indicators and an EA sharing identical code paths.
Core point: smoothing is filtering. The SMA is a weak low-pass filter: material lag plus a poor frequency response that leaks noise. A 2-pole IIR design reduces noise with less delay.
Library design uses stateful recursive filters with explicit history, warm-up handling, and a single include file as the source of truth. No iCustom dependency for the EA.
Implemented tools: Super Smoother (2-pole low-pass), Roofing Filter (2-pole high-pass cascaded into Super Smoother to isolate a tradeable band), and Even Better Sinewave, which flags non-cycling regimes by sustained railing near Β±1.
