AlphaLondon Pro

AlphaLondon Pro

Overview
AlphaLondon Pro is a MetaTrader 5 Expert Advisor for gold quoted in US dollars. It looks for session breakouts with price and volatility filters, then manages positions with protective stops and staged exits. Decisions run inside MT5; no external Python service, DLL or paid data subscription is required.

Position sizing
Choose adaptive percentage risk, strict percentage risk or fixed lots. Adaptive mode adjusts risk using the strategy’s controls and US-dollar context. Strict mode uses the selected equity percentage and initial stop. Fixed mode requests the chosen volume without the adaptive multiplier. Broker volume steps and margin requirements still apply. If strict risk cannot fund the minimum lot, the entry is skipped rather than increasing risk. Partial exits depend on the broker’s volume step.

Operation and protections
The strategy evaluates M5 data with higher-timeframe context. Attach it to your broker’s gold/USD M5 chart. It can remain inactive when setup or execution conditions are not met. It does not use a grid or increase lots to recover losses.

Entries include protective stops. The EA checks quotes, sessions, margin, prices and order filling. Configurable daily and account drawdown controls, persistent state and reconciliation of unconfirmed orders support operation across restarts. A hard drawdown halt is preserved across restarts. Stops cannot guarantee a maximum loss during gaps or slippage.

Accounts and data
The same strategy runs on demo and real accounts. Market demonstration downloads follow MetaTrader’s Strategy Tester restrictions. On netting accounts, reserve the gold symbol for this EA; do not mix manual trades or other robots in the same net position. Use a distinct magic number for independent instances.

Adaptive mode requires usable US-dollar reference data available in MT5 from the broker and waits when that history is unavailable. Strict percentage and fixed-lot modes do not apply the adaptive dollar multiplier. Keep MT5 or a configured VPS running to manage positions.

Clock and economic calendar
Live automatic clock mode measures the connected server’s UTC offset. Historical tests use a documented server time policy. For unrecognized servers, verify the historical offset and daylight-saving inputs against the broker’s records.

The optional live MT5 economic-calendar filter is OFF by default. Keep it off in Strategy Tester: this implementation does not provide native calendar history there. Enabling it in live trading changes the eligible entries and is not represented by calendar-off backtests.

Testing and installation
Install from your MT5 Market account, open the broker’s gold/USD M5 chart, select sizing and risk inputs, and enable algorithmic trading. Check the dashboard and Experts journal. For reproducible tests, use every tick based on real ticks with matching dates, symbol, capital, currency, fees, delay and inputs.

Quotes, spreads, swaps, commissions and sessions differ between brokers and can change results. A missing setup, risk halt, missing history, closed session, insufficient margin or unresolved order can prevent entry.

Risk disclosure
Gold trading involves risk of loss. Historical and optimized results do not guarantee future performance or a prop-firm challenge pass. Evaluation rules, including floating losses and daily reset conventions, must be checked separately. Test on your own broker before using real money.
