AlphaLondon Pro

AlphaLondon Pro is a MetaTrader 5 Expert Advisor developed specifically for Gold (XAUUSD).

The EA focuses on London-session breakout opportunities, combining price structure, volatility and higher-timeframe context to identify situations where Gold may transition from consolidation into directional expansion.

AlphaLondon Pro is not a grid or martingale system. Every trade is initiated from a defined strategy setup and managed with protective stops and progressive exit logic.

Version 1.11 introduces flexible position sizing, strengthened execution controls and improved operational protection while retaining the core AlphaLondon Pro trading logic.

No DLL, Python runtime, external signal service or paid data subscription is required.

Trading Logic

AlphaLondon Pro searches for breakout opportunities around the London trading session.

The EA evaluates market structure and volatility before allowing an entry. A breakout alone is therefore not sufficient: the complete strategy conditions must be satisfied before a position is opened.

The system uses M5 market data together with higher-timeframe context.

Periods without trades are normal. AlphaLondon Pro is designed to wait for qualifying conditions rather than maintain constant market exposure.

For normal operation, attach the EA to your broker's XAUUSD M5 chart.

Position Sizing

Version 1.11 provides three position-sizing modes.

Adaptive Risk

This is the strategy's native sizing approach.

It preserves AlphaLondon Pro's internal risk adjustments and market-context logic when determining position exposure.

Strict Risk Percentage

The requested position size is calculated from:

• Current account equity

• User-selected risk percentage

• Initial Stop Loss distance

If the broker's minimum tradable volume would exceed the requested risk budget, AlphaLondon Pro skips the trade rather than silently increasing the intended risk.

Fixed Lots

The EA requests the lot size selected by the user.

Broker minimum and maximum volume, lot step, available margin and other trading restrictions still apply.

Fixed lot size does not mean fixed monetary risk because the financial exposure also depends on Stop Loss distance and the broker's XAUUSD contract specifications.

Trade Management

AlphaLondon Pro manages positions dynamically after entry.

Depending on the active trade conditions, the system can use protective and progressive exit mechanisms rather than relying exclusively on a single static exit.

Broker volume restrictions can affect partial position management. In particular, partial closure may not be possible when trading at or near the broker's minimum lot size.

The MetaTrader terminal or VPS must remain connected when dynamic management is required.

Execution Protection

Before sending an order, AlphaLondon Pro checks relevant execution conditions including:

• Market quotes

• Trading session

• Stop-distance requirements

• Available margin

• Broker volume restrictions

• Supported order filling mode

The EA also maintains operational state across terminal restarts and includes reconciliation mechanisms designed to avoid blindly repeating an order when the result of a previous request is uncertain.

Protective state is persistent: restarting MetaTrader does not automatically reset an active global protection condition.

These mechanisms improve execution control but cannot eliminate trading risk.

Market gaps, slippage, latency, broker execution and connectivity failures can cause realized losses to differ from the intended risk.

Economic News Filter

AlphaLondon Pro includes an optional filter based on the native MetaTrader 5 economic calendar.

The filter is disabled by default.

When enabled, it can restrict new entries around selected economic events.

No external news API or paid economic-data subscription is required.

Important: enabling the news filter changes the set of trades that may be taken. Historical tests produced with the filter disabled should therefore be reproduced with the filter disabled.

Live, Demo and Strategy Tester

The purchased AlphaLondon Pro EA supports:

• MT5 Live accounts

• MT5 Demo accounts

• MT5 Strategy Tester

The free MQL5 Market Demo operates under MetaTrader Market tester restrictions. These restrictions do not mean that the purchased product is limited to Demo trading.

Both hedging and netting account structures require appropriate setup.

On a netting account, avoid combining unrelated trading systems on the same XAUUSD symbol because MetaTrader may represent their exposure within the same net position.

Use a different Magic Number for each independent AlphaLondon Pro instance.

Broker Time

AlphaLondon Pro includes broker-time handling because session timing is an important component of the strategy.

In live operation, AUTO mode measures the connected trading server's UTC offset.

Historical testing requires appropriate server-time and daylight-saving settings. If your broker uses a different historical time convention, configure the corresponding settings before comparing results.

Incorrect broker-time configuration can change session boundaries and therefore change trades.

Installation

1. Install AlphaLondon Pro through MQL5 Market.

2. Open your broker's XAUUSD M5 chart.

3. Attach AlphaLondon Pro.

4. Select your preferred position-sizing mode.

5. Review the risk and execution settings.

6. Verify broker-time configuration.

7. Configure the optional news filter if required.

8. Allow the necessary price history to load.

9. Check the AlphaLondon Pro dashboard and Experts log.

10. Enable Algo Trading when the EA is ready.

Use a unique Magic Number for every independent instance.

Backtesting

For the closest possible comparison with published AlphaLondon Pro tests, use real ticks and reproduce the same:

• Symbol and broker data

• Testing period

• Initial deposit

• Account currency

• Leverage

• Trading costs

• Execution assumptions

• Broker-time settings

• EA inputs

Different XAUUSD feeds can produce different breakout prices and therefore different trades.

Spreads, commissions, swaps, execution, contract specifications, historical data and broker trading hours can all affect results.

A Strategy Tester result is a historical simulation and should not be interpreted as live trading performance.

Before Trading with Real Funds

Test AlphaLondon Pro with your own broker in the MT5 Strategy Tester and on a Demo account before using real capital.

AlphaLondon Pro does not use martingale or grid recovery, but this does not make the strategy risk-free.

Stop Loss orders and software protections cannot guarantee a predefined maximum loss during gaps, extreme slippage, execution failures or connectivity problems.

Historical and optimized results do not guarantee future performance. Trading Gold with leverage involves substantial risk and can result in the loss of the entire allocated capital.
