CPortfolioAnalyzer is extended beyond basic equity and correlation views to address multi-EA risk visibility and operational controls. Key additions include a strategy-level Drawdown Timeline Heatmap that logs peak-to-exit drawdowns per trade, plus a monitoring loop that enforces user thresholds without blocking the terminal UI.

A mitigation engine adds escalating actions: close positions and delete pending orders, persist strategy blocks via terminal Global Variables, or disable terminal AutoTrading through Windows API messaging. Export is upgraded with detailed CSV plus a styled multi-worksheet Excel XML workbook written directly from MQL5.

A hybrid MQL5-Python pipeline bypasses WebRequest sandbox limits by generating a temp CSV and a standard-library Python script, executing asynchronously via ShellExecuteW, and polling results on OnTimer. Retur...

A new MT4 support/resistance indicator is available, based on swing-pivot detection rather than highest/lowest-over-N-bars. Nearby pivots are clustered into zones and ranked by verified touch count, shown directly on-chart (for example, “x8”) to distinguish frequently tested levels from recent ones.

Chart readability is handled with adaptive zone thickness to prevent overlap across timeframes, plus a distance-based filter that hides zones far from current price. An optional higher-timeframe overlay can display longer-period zones in a separate color and is automatically skipped when it would duplicate the active timeframe.

Proximity alerts are included (pop-up and sound) with a cooldown to reduce repeated triggers. Full source is provided. For information purposes only; no trade execution or management is performed.

Rolling Return Autocorrelation Regime Oscillator reframes autocorrelation for live regime monitoring. Instead of plotting correlation by lag once, it fixes a lag (often 1) and recalculates Pearson autocorrelation each bar over a rolling window of returns, producing an oscillator-like series.

Positive values indicate statistically meaningful return persistence at that lag, which tends to align with trend-following conditions. Negative values indicate serial reversal, which tends to align with mean reversion and range behavior. Readings inside the significance bands suggest no reliable dependence for the chosen window and lag.

Significance bands are computed dynamically at ±Z/√N to separate signal from sampling noise. A raw per-bar estimate is shown alongside an EMA-smoothed line; the smoothed line is the practical regime filter, while the raw line hig...

Order Block Mitigation Tracker focuses on what happens after an order block is drawn. Zones are treated as time-sensitive: once price trades back into the area, the block is marked as mitigated, the rectangle fades, and the exact mitigation bar is annotated. This makes “fresh vs already used” visible without relying on identical static boxes.

Detection uses an ATR-based impulse filter. On each closed candle, body size is compared to ATR times a configurable multiplier. A qualifying impulse confirms the prior opposite-color candle as the order block, keeping signals tied to displacement rather than minor swings.

Mitigation can be defined by wick touch or candle close. Active blocks can extend forward; mitigated blocks can remain on chart for a fixed bar count. Key inputs include lookback bars, ATR period, impulse multiplier, max tracked blocks, and re...

A dynamic trend channel for MT5 can avoid the common weakness of fixed-level indicators by sizing its boundaries with volatility. This design builds a trend-following channel from True Range, then stabilizes ATR with two smoothing stages: Wilder’s RMA followed by an SMA, producing an adaptive width used to expand or contract with market conditions.

Channel levels are computed per bar from average highs/lows over a lookback window plus/minus the final ATR value. Trend state is derived from price interaction with these boundaries, while a trailing trend line switches between upper and lower levels to track direction.

On the chart, the indicator combines a filled region (trend line vs. HL2 midpoint), trend-colored candles, and arrows only when bullish/bearish transitions are confirmed—useful for clearer discretionary analysis and as a foundation for aut...

Machine learning expanded retail signal generation, but by the early 2010s automated mining increased low-value, short-lived alphas. Scale created noise, limited explainability, and weak audit trails.

In 2016, Zura Kakushadze proposed formulaic alphas: trading signals expressed as algebraic formulas that can be parsed, ranked, neutralized, and combined into a single aggregate signal, without embedding them into a full execution strategy.

A basic example is (close-open)/(high-low+0.001), producing a signed momentum score. The framework defines an expression language: operators, time-series transforms, cross-sectional rank, and group neutralization over inputs like OHLCV, returns, VWAP, cap, and ADV.

For evaluation at scale, backtests mix alpha quality with execution choices. Information Coefficient (Pearson correlation between alpha scores and forwar...

Bonobo Optimizer (BO) is a population-based optimization method published in 2021 by Amit Kumar Das and Dilip Kumar Pratihar. Each individual represents a candidate solution, with an alpha individual tracking the current best.

Core mechanics use fission-fusion subgroups and three update strategies: randomized mating toward alpha plus a subgroup partner (scab/scsb may exceed 1), low-probability extra-group mating using boundary extremes with heavy-tailed beta coefficients, and consortship mating with a direction flag based on relative fitness and exp(-rand) decay.

Selection applies a strict acceptance rule: always accept improvements, otherwise accept with small probability to retain diversity. Parameters adapt via positive/negative phases, shifting subgroup size, randomized mating rate, and extra-group probability.

LightGTS tokenizes time series by FFT-based period patching, then applies flexible projection to handle variable-length cycles. Transformer Encoder blocks consume these tokens, and Periodical Parallel Decoding emits the forecast in one pass, with a resize stage preserving periodic consistency.

Rotary Positional Encoding replaces additive position vectors by rotating Q/K coordinate pairs. It is parameter-free, requires even embedding size, and improves relative shift handling under variable windowing.

An OpenCL RoPE implementation maps work-items over (D/2, tokens, variables), uses float2 pairs, precomputed sin/cos tables, and minimizes global reads. A backward kernel applies the inverse rotation to propagate gradients.

In MQL5, a CNeuronRoPE wrapper validates even dimensions, builds a cos/sin matrix once on CPU, and queues forward/backward kernels. Encoder...

The project evolves from a basic FastAPI + Jinja2 MT5 process controller into a terminal manager that can surface live trading-account metrics in the UI. Hard-coded terminal paths are replaced by startup-selectable configuration, preparing the app for real deployments with many instances.

A new endpoint (/instances/{name}) returns per-terminal status as JSON, with request handlers organized into a dedicated controller class. The UI is refined using Bootstrap and jQuery, enabling simple periodic polling to refresh terminal data without manual page reloads.

Account and terminal characteristics are read via the MetaTrader5 Python library by connecting to a specific terminal executable (portable mode), using a short initialize() timeout to avoid blocking on disconnected terminals, then querying terminal_info(), account_info(), and last_error() before ...

SuperTrend is a volatility-band indicator rendered as a single line that flips sides by trend. It combines ATR with a ratchet that preserves prior band state, so each bar depends on the stored state of the previous bar.

Most “repainting” reports are state-management faults: closed bars changing due to broken recursion, series/normal indexing mismatches, or buffer history being reset. In MT5 this is amplified by call-based execution, so recursive state must persist across calls.

A robust approach uses calculation buffers (sUp, sDn, sTrend) instead of manually resized arrays, creates the ATR handle once in OnInit, and copies ATR data defensively. Live updates typically reprocess only the forming bar and the last closed bar.

Arrows should be delayed until reversals are no longer at risk of being invalidated by the next ticks.

MetaTrader 5 positions are isolated, which makes basket-level risk control awkward when trades are correlated. The article solves this with CBasketManager: positions are grouped by a basket ID stored in POSITION_COMMENT using a simple “BASKET:ID” convention, enabling basket-wide P&L tracking and coordinated exits.

The design separates concerns cleanly: a scanner aggregates state into a single CBasketInfo snapshot (sum P&L, long/short volume, volume-weighted pips, distance to stop), an executor handles order sends and closes legs safely in reverse order, and a stop registry enforces a unified equity threshold via a callback so risk logic stays decoupled from execution.

Practical details target real brokers: filling mode is resolved from SYMBOL_FILLING_MODE to avoid common retcode failures, symbols like gold are configurable and selected early to ensure prope...

Broker Execution Diagnostics MT5 is a read-only script that reports symbol constraints commonly linked to invalid volume, invalid stops, and inconsistent risk calculations.

Output includes digits, point, tick size, tick value, current spread (points), min/max/step volume, and a conservative normalized volume for a requested size. It also reports stops and freeze levels in points and price distance, plus trade mode and execution mode values. Optional checks cover entry-to-Stop-Loss distance and an OrderCalcProfit estimate in account currency.

Inputs: InpRequestedVolume for normalization, optional InpEntryPrice and InpStopLossPrice for distance and P/L checks, plus InpShowOnChart to print the report on-chart.

Session Sweep Reversal Detector flags intraday reversals around completed session boundaries. It plots the finished session high/low as forward reference lines, then monitors post-session price action for a liquidity sweep.

A sweep requires price to breach the frozen high/low by more than a configurable buffer, then close back inside the range within a limited number of bars. Breaches that fail to reverse in time are treated as breakouts and ignored.

Signals are shown as arrows: bullish when the session low is swept and price closes back above it, bearish when the session high is swept and price closes back below it. Key inputs include session start/end hours, sweep buffer in pips, reversal bar limit, and the number of prior sessions displayed. Most relevant on M5–M30, commonly aligned to London or New York hours on major FX pairs.

Trade Transaction Trace Logger is a read-only MT5 Expert Advisor designed to diagnose the lifecycle of orders, deals, and positions. It records OnTradeTransaction events in arrival order to a local CSV file and can optionally mirror a compact line to the Experts Journal.

Captured fields include a monotonic event sequence with server time, transaction type, symbol, resolved magic number, and order/deal/position tickets. It also logs order type and state, deal type, price, trigger, SL/TP, volume, plus request action and server retcode/comment. If an event lacks context, the core attempts resolution via request data, live orders, order history, deal history, or current positions.

Configuration covers symbol scope (chart or all), magic filtering (-1 or exact), CSV filename, Common Files storage, and Journal printing. The module sends no trade requests, uses no DLL/W...

Stop Geometry Visualizer for MT5 is a free, read-only indicator that renders broker Stops Level and Freeze Level as chart references.

It displays current Bid, Ask, spread, Stops/Freeze values in points and price distance, plus upper/lower geometry references for Buy Stop, Sell Stop, Buy Stop Loss, and Sell Stop Loss. Optional freeze reference lines can be enabled. It also reports tick size, volume min/step/max, and filling-mode flags.

A timer-based refresh is configurable via InpRefreshSeconds. Visibility of stop/freeze references and change logging is controlled by inputs, along with line color settings. When a broker reports zero Stops or Freeze, lines are omitted and the dashboard explicitly shows zero.

No orders are placed, modified, or deleted. Lines are diagnostic only; final validation should use the current broker state and OrderCheck.

Round Trip Cost Reconciler is a free, read-only MT5 utility that generates two CSV outputs for trade cost accounting. One file contains filtered deal records. The second aggregates buy/sell deals by DEAL_POSITION_ID to produce position-level round-trip figures.

Partial fills are consolidated into volume-weighted entry and exit prices. Commission, swap, and fee remain separated from gross trading result, enabling cleaner reconciliation of broker-recorded costs versus PnL.

Reports include deal/order/position identifiers, symbol, magic number, direction, entry type, timestamps, price/volume, broker profit and costs, total entry/exit volume, weighted prices, gross result, total costs, net result, deal count, and lifecycle status.

Lifecycle states: COMPLETE, OPEN_OR_INCOMPLETE, EXCESS_EXIT, and COMPLEX_REVERSAL (INOUT reversals are not simplified).

Broker Session Schedule Inspector for MT5 reads the weekly trading-session schedule directly from the connected broker, without using predefined London, New York, or other global session templates.

The script can be run against the current chart symbol, a comma-separated custom list, or all visible Market Watch symbols. For each symbol it enumerates sessions returned by SymbolInfoSessionTrade, checks whether current server time is inside a scheduled window, and identifies the next open or close transition. Trade mode and synchronization status are also reported.

Midnight-crossing sessions are marked with (+1d). If the broker does not provide schedule data, the output returns SCHEDULE_UNAVAILABLE rather than generating fallback hours. Optional CSV snapshots with timestamps can be written to the terminal Common Files folder.

Inputs include symbol scope, custom...

Look-ahead bias remains a primary reason ML trading models fail on non-stationary live data. It appears when labels are derived from future price movement, producing inflated backtests, weak out-of-sample results, and low robustness due to overfitting.

A proposed alternative is oscillator-based labeling that avoids future information. Labels are generated from overbought/oversold thresholds with an added “do not trade” zone, enabling cleaner cross-validation and simpler decision boundaries.

Key limitations persist: oscillator selection and parameterization, poor behavior in trends, and instrument dependence. Adding profitability checks can smooth equity curves but reintroduces look-ahead.

Implementation details include Numba-accelerated indicator calculation, threshold-to-label mapping, optional profitability filtering, and ONNX export for deploymen...

Financial time series work increasingly depends on probabilistic forecasts, not point estimates. Longer horizons amplify error accumulation, volatility sensitivity, and compute costs, especially under regime shifts driven by earnings, macro data, and geopolitics.

K²VAE combines Koopman linearization, Kalman-style online correction, and a VAE for scenario generation. Tokens are built from multivariate patches to capture cross-asset interactions, then mapped into an observable space where a learned Koopman operator rolls dynamics forward.

Residuals from the linear rollout feed KalmanNet via control inputs, producing updated state and covariance per step. The decoder samples multiple future trajectories, returning distributions with confidence intervals suited for risk-aware trading and portfolio sizing.
