ONNYX AI Ver. 3.29
A multicurrency Expert Advisor for MetaTrader 5 hedging accounts. It maps supply and demand zones, evaluates entries when price touches a valid zone, and manages trades through a unified portfolio dashboard.
The system combines rule-based market structure, zone quality scoring, trend and higher-timeframe confirmation, economic-news protection, and an optional external AI validation layer. External AI can be bypassed at any time. No API credential is required for the local decision engine.
The local decision engine includes an embedded ONNX Neural Network with a 12-24-12-1 architecture. It runs directly inside MetaTrader 5 using automatically prepared market features and does not require an external neural-network service.
ONLINE LEARNING IN VERSION 3.26
Version 3.26 adds a persistent adaptive learning layer for each broker symbol. The EA can build its own symbol-specific dataset from trading observations, update separate model weights incrementally, and reuse the learned state in later sessions. Dataset and weight files are created automatically when needed and loaded again after the EA or MetaTrader 5 restarts. Learning is isolated per symbol so that instruments with different price behavior do not share the same adaptive state. This adaptive layer supports the local decision process and does not guarantee profitable outcomes.

HOW IT WORKS
1. The EA builds fresh supply and demand zones from historical price action.
2. It scans the chart symbol and, when enabled, other available broker symbols.
3. A candidate must be inside a valid zone and pass the configured local filters.
4. The news filter checks the currencies belonging to that candidate symbol.
5. Optional AI validation can allow or block the candidate and records its reason.
6. The order is normalized to the symbol's tick size, volume step and trading limits.
7. The EA manages the position with the selected exit, trailing or basket rules.
INPUT PARAMETERS AT EA LOAD
MetaTrader 5 reads these inputs when the EA is attached, reloaded, recompiled, or when an input is changed. An input change reinitializes the EA. Values are normalized to each symbol's tick size, volume step and broker trading limits. Existing EA-managed positions are reconciled with the active basket and protection settings after reload.
01. LOT, TAKE PROFIT & STOP LOSS
- Trade All Broker Symbols: False trades only the chart symbol. True enables the multicurrency scanner for available broker symbols and automatically handles prefixes and suffixes.
- Follow Trend Direction: Allows first entries only in the direction accepted by the EA trend engine.
- Initial Lot Size: Base volume for a first entry, normalized to the symbol minimum, maximum and volume step.
- Take Profit Method: Selects fixed broker ticks, ATR-based distance or neural-based take profit.
- Take Profit (broker ticks): Fixed TP distance when the fixed-tick TP method is selected.
- ATR Multiplier for TP: Multiplies ATR to calculate TP when ATR TP is selected.
- Stop Loss Method: Selects fixed broker ticks, ATR-based distance or neural-based stop loss for non-martingale entries.
- Stop Loss (broker ticks): Fixed SL distance when the fixed-tick SL method is selected.
- ATR Multiplier for SL: Multiplies ATR to calculate SL when ATR SL is selected.
- Close Profit at Next Opposite Zone: Closes a profitable position if price reaches the next opposite supply or demand zone before TP.
02. TRAILING STOP - SINGLE ENTRY
- Trailing Stop Method: Disables trailing or selects fixed-tick, ATR, break-even or neural trailing for managed single entries.
- Start Trailing After Profit (broker ticks): Profit distance required before fixed-tick trailing starts.
- Trailing Distance (broker ticks): Distance maintained behind price by fixed-tick trailing.
- ATR Trailing Start Multiplier: ATR multiple required before ATR trailing starts.

05. DRAWDOWN PAUSE FOR NEW PAIRS
- Enable New-Pair Drawdown Pause: Temporarily blocks first entries on new symbols when account drawdown reaches the pause threshold. Existing baskets continue to be managed.
- Pause New Pairs at Account DD (%): Account drawdown percentage that starts the new-symbol pause.
- Resume New Pairs Below Account DD (%): Lower drawdown percentage that allows new-symbol entries again.
06. FIRST-ENTRY ACCURACY FILTER

WEBREQUEST SETUP FOR OPENAI
External OpenAI validation uses the OpenAI Responses API. Add the following base address to the MetaTrader 5 WebRequest allowlist:
Setup:
1. Open Tools > Options > Expert Advisors in MetaTrader 5.
2. Enable "Allow WebRequest for listed URL".
3. Add https://api.openai.com as a new allowed URL.
4. Click OK, reload the EA, set Bypass OpenAI Validation to false, and enter your own API key in OpenAI API Key.
The EA sends requests to https://api.openai.com/v1/responses. Add only the base address https://api.openai.com to the MT5 allowlist. Do not place the API key in the URL list.
External validation is not called when Bypass OpenAI Validation is true, the API key is empty, or the EA runs in the Strategy Tester. In those cases, the local rule engine, embedded ONNX model and per-symbol online learning remain available.
Troubleshooting:
- WebRequest error or code -1: check the MT5 URL allowlist, internet access and terminal permissions.
- HTTP 401: the API key is invalid, expired or incorrectly entered.
- HTTP 403: the API account or project does not permit the request.
- HTTP 429: the API rate limit or account quota has been reached.
SETUP NOTES
- Designed for MetaTrader 5 hedging accounts.
- Attach one instance to a chart and keep algorithmic trading enabled.
- The active chart timeframe is used by the chart engine and scanner logic.
- Multicurrency mode requires the relevant broker symbols and price history.
- Economic Calendar availability depends on the terminal and broker environment.
- Online-learning files are created and maintained automatically in the terminal file environment; no manual dataset installation is required.
- Optional external AI validation requires the user's own API credential and terminal WebRequest permission. Leave the key empty or enable bypass to use only the local engine.
- Test all parameters in the Strategy Tester and on a demo account before live use.
FORWARD TEST UPDATE
Forward-test results will be added to this product page after a representative live observation period has been completed. The update will include the tested period, account conditions, major settings and performance statistics.
RISK NOTICE
Trading involves substantial risk. Results depend on market conditions, broker execution, symbol specifications and user settings. Historical tests do not guarantee future performance. Martingale and recovery modes can increase exposure quickly. Use conservative limits and sufficient risk controls.
