A position manager for MT5 targets grid and martingale baskets on XAUUSD, forex, or indices by pairing one strong winner with one deep loser. It calculates profit plus swap and commission, then closes both when the combined result meets a configured minimum, closing the winner first to lock gains. No entries are opened.

Filtering can be limited to the chart symbol or applied across all symbols, and to a single magic number or all positions, including manual trades. Optional basket-level take profit and stop loss in account currency can flatten all managed positions.

Execution is defensive: each close checks the return code and retries after a pause. A minimal panel shows managed positions, floating result, best and worst tickets, pair sum versus the threshold, and controls for pair close, close all, and pause. Pair logic is isolated in XP_FindPair and XP_Clos...

Major LLM vendors are aligning on shared expectations for model interoperability and evaluation. Gemini, Mistral, Claude, and Perplexity are signaling interest in common interfaces, clearer capability reporting, and more consistent safety and reliability testing.

For engineering teams, this can reduce integration friction across providers, improve portability of prompt/tooling stacks, and make vendor comparisons less ambiguous. Focus areas likely include standardized tool-calling schemas, response formatting guarantees, and reproducible benchmark disclosure.

If this coordination continues, procurement and architecture decisions may shift from vendor-specific adapters toward simpler abstraction layers, with more attention on latency, cost, context limits, and compliance.

DataSnooping.mqh adds data-snooping controls to strategy and parameter optimizations, addressing whether the top result is statistically better than a benchmark or simply the best outcome among many trials.

It implements Hansen’s SPA test, White’s Reality Check, the Romano-Wolf StepM procedure, and the Hansen-Lunde-Nason model confidence set. Resampling is done with a stationary bootstrap to preserve dependence in daily returns, with a configurable seed and no DLL requirement.

Components include CSuperiorAbility (SPA p-values, Reality Check, critical values, and StepM results), CModelConfidenceSet (per-strategy p-values and best-set selection using R or max statistics), and CStationaryBootstrap (bootstrap indices and efficient mean computation). A provided example generates 100 moving-average rules or reads CSV returns, illustrating how single-test...

Session Range Breakout displays the intraday high/low for up to three configurable sessions and keeps those levels visible after the session ends by extending them to the right.

Sessions are defined by start hour (inclusive) and end hour (exclusive) in server time. While a session is active, the running high and low are tracked. After the close, both levels are finalized and drawn as dotted lines, with optional “NAME H / NAME L” labels and an optional thin range rectangle. Values are not recalculated later, so the output does not repaint.

Configuration includes per-session enable/disable, name, hours, and color, plus history depth, extension length (bars), and line width. Optional features cover labels, the range rectangle, and alerts (popup, sound, push) when a bar closes outside a session range. An auto-zoom option can rescale the chart on load to ...

Swap is presented as a single value in the terminal, but it consists of two components: carry (interest-rate differential) and broker markup (financing fee). Carry changes sign between long and short, while markup is paid in both directions.

Given long and short swaps for a symbol, markup and carry can be derived as:
markup = -(long + short) / 2
carry = (long - short) / 2

The script normalizes all swap calculation modes into one comparable metric: annual percentage of the position notional. This enables direct comparison across FX, metals, indices, and commodities.

This matters for multi-week holding strategies where daily markup compounds into a material drag. A 0.75% annual markup on FX or 2.5% on index CFDs can eliminate expected returns even when price-only backtests look acceptable.

Output includes an on-chart table with risk bands, a full ranked...

A non-repainting three-bar Fair Value Gap detector for MT5 is available, based strictly on closed-bar data. Each imbalance is drawn as a rectangle with an optional 50% Consequent Encroachment line. Gap levels are derived from three closed candles (pre-impulse, impulse, and the candle that leaves the imbalance) and are persisted without later rewriting.

The gap lifecycle is implemented as an explicit state machine. In TRIM mode, a gap is anchored to the first closed bar that trades into it, preventing rectangles from extending into future bars after mitigation. Mitigation display is selectable: TRIM shortens, DELETE removes, DIM greys out, and NONE leaves full length. Open gaps can be forward-extended via a configurable bar count.

Processing is incremental, scanning only newly closed bars instead of rebuilding history on each tick. A self-audit can re...

A trade manager for MetaTrader 5 that splits take profit into up to five levels (TP1–TP5) for any existing position on XAUUSD, FX pairs, indices, or crypto. Distances can be set in points or as multiples of stop loss (R), with per-level close percentages and optional “close remainder on last active level”.

The tool monitors manual trades and positions opened by other experts, with filtering by symbol scope and magic number. It never opens trades and performs partial closes immediately on level hits, rounding volumes to broker lot step and closing the position fully if the remainder would fall below minimum lot. Taken levels are persisted via terminal global variables to avoid repeats after restarts.

Risk controls include optional automatic stop loss assignment, breakeven move after a selected TP level with offset, and trailing stop that activates only after...

GM Matrix Monitor is a read-only dashboard for supervising multi-EA accounts without repeatedly opening the terminal. It aggregates per-magic net P/L by combining closed deals with current floating profit, and presents each EA’s running result in a single column.

Risk visibility is provided via real-time drawdown, calculated from current equity against a configurable reference balance. It also tracks realized losses since day start against a daily-loss cap, and signals proximity to freeze and liquidation thresholds using color states (green/amber/red) based on user-defined percentages.

Setup consists of attaching the panel to a chart, entering a comma-separated magic list, selecting a base equity (or current balance), and configuring freeze, liquidation, and daily-loss limits. The tool reads history and positions only; it does not send, modify, or close ord...

EAs that trade New York hours need a reliable broker server offset to UTC. Many brokers run UTC+2 in winter and UTC+3 in summer, but apply either US or EU daylight rules, creating 1-hour errors during the spring and autumn gaps between clock changes.

TimeTradeServer() - TimeGMT() works on live charts but depends on the local PC clock and becomes unusable in Strategy Tester, where TimeGMT() mirrors simulated server time. BrokerClock.mqh instead infers the offset from H1 history by using the known weekend close for CME-linked symbols: the last H1 bar before the weekend ends at 17:00 New York, which maps to a specific UTC instant.

The library scores candidate offset rules (fixed, US DST, EU DST) across up to 60 weekends, prioritizing the last 8 weeks, then breaks ties with the full set. It provides current server offset, live cross-check offset, calendar-based NY/L...

An ADX-based indicator automates detection of consolidation ranges by tracking trend strength decay. It replaces discretionary price-action calls with a repeatable rule set that flags when a prior trend is losing momentum and price action becomes choppy, where risk typically increases for in-range trading.

Sensitivity is controlled by InpSlopeBars, comparing ADX[shift] to ADX[shift - InpSlopeBars]. Lower values react faster and add noise; higher values smooth readings and favor broader fades.

Confirmation uses InpDeclineBars to require multiple consecutive negative ADX slope samples before opening a range.

Range termination is managed by InpEndOnStrengthRise (optional close on strength recovery) or by price breakout only. Breakout validation uses InpBreakoutPercent, while InpMinRangeBars enforces a minimum range duration before drawing.

The article builds an MT5 Expert Advisor that trains a fully connected CNet model to predict Bill Williams fractal pivots one bar earlier than the standard indicator’s confirmation delay. It frames the task as supervised learning: feed the latest market context, then label the previous bar after the next candle closes.

Inputs combine normalized candle features (Close/High/Low relative to Open), time components (month, hour, weekday), volumes, and four standard oscillators (RCI, CCI, ATR, MACD), producing 12 values per bar across a configurable history window. The network uses 4 hidden layers starting at 1000 neurons and shrinking by 70% per layer with a floor of 20.

Two output designs are compared: a single tanh neuron encoding buy/sell/none, or a 3-neuron probability classifier. Implementation details include loading a saved trained network, tracking MSE and hit...

This article refactors an MQL5 SQLite helper to make SQL script execution cleaner, testable, and future-proof. The original design is reworked into a single C_DB_SQL class with a constructor that opens the database (optionally in-memory) and a destructor that guarantees proper close, reducing lifecycle bugs.

Script execution is improved by returning status text instead of printing to the terminal, enabling UI-agnostic error reporting. Failures are traced back to the exact script line, while successful runs return null, keeping calling code simple.

The key upgrade is supporting SQL embedded as an MQL5 resource. The implementation converts resource text into a byte buffer, parses it into statements, and reuses one private ExecSQL pipeline for both files and resources. This encapsulation keeps the public API stable while allowing future backends (e.g., client-s...

Live tick transfer from MetaTrader 5 to Python can avoid per-tick allocations by sharing an Apache Arrow columnar layout in shared memory and importing it with zero copies.

Part 1 implemented the MT5 writer: two double-buffered slots, fixed headers, six 8-byte columns with padded buffers, and a lock-free seqlock where odd generation means “writing” and even means “stable”.

This follow-up implements the Python reader with ctypes definitions of ArrowArray and ArrowSchema, points their buffers directly into an mmap, and builds a pyarrow.RecordBatch without struct.unpack loops or boxing.

A standalone benchmark reproduces the exact memory layout locally and compares the zero-copy import path against legacy field-by-field unpacking across batch sizes.

Notes: schema and column-count contracts must match; seqlock assumes correct memory ordering; imported batch...

RAFT is adapted from optical flow to market forecasting by treating past vs present as two “frames” and iteratively refining a prediction instead of producing a one-shot output. The core gain is an all-pairs correlation field that compares current features against a historical stack, capturing global interactions rather than local matches.

A key upgrade for finance is replacing fixed context with a recurrent contextual encoder, letting the model track regime shifts (volatility, liquidity, correlation changes) as an internal state. This keeps context current without the cost of expanding the entire history window.

In MQL5, the CNeuronRAFT object assembles encoders, multiscale stack correlation, concatenation, GRU-based refinement, and a stabilizing residual path. The model predicts a delta update each iteration, improving training stability and making real-t...
