Purpose
Develop a transparent and conservative Expert Advisor for MetaTrader 5. Profit is not guaranteed; acceptance is based on correct implementation, risk controls and reproducible testing.
1. Platform and instruments
- Native MQL5 Expert Advisor for MetaTrader 5.
- Symbols: EURUSD and USDJPY.
- Working timeframe: H1. Higher-timeframe trend filter: H4.
- Must support standard broker symbol suffixes/prefixes and both netting and hedging accounts.
2. Entry logic
Long:
- The last completed H4 candle closes above EMA(200).
- The last completed H1 candle closes above the highest high of the previous 20 completed H1 candles.
Short: exact opposite conditions.
- Signals must use completed candles only. No repainting or look-ahead.
- One position per symbol and no more than two positions total.
3. Exit logic
- Initial stop loss: 2 x ATR(14) on H1.
- Initial take profit: 3 x ATR(14) on H1.
- Configurable ATR trailing stop activated after profit reaches 1 x ATR.
- All periods and multipliers must be external input parameters.
4. Mandatory risk controls
- Default risk per trade: 0.25% of current equity, calculated from actual stop distance and symbol properties.
- Daily equity loss limit: 1%. When reached, close positions opened by the EA and block new trades until the next broker day.
- Total drawdown limit: 5% from the highest recorded equity since EA start. When reached, close EA positions and disable new trading until manual reset.
- The 5% control must persist after terminal/VPS restart.
- No martingale, grid, averaging down, recovery mode or increasing risk after losses.
- Protection for invalid lot size, insufficient margin, maximum spread and slippage.
- Developer must disclose that gaps/slippage can make actual loss exceed a programmed threshold.
5. Filters and controls
- Configurable trading days and trading session.
- Configurable maximum spread for each symbol.
- Optional high-impact news filter using the built-in MQL5 Economic Calendar for USD, EUR and JPY, with configurable pause before/after news.
- Magic Number, order comment and emergency Close All / Disable Trading button.
- On-chart panel: equity, current daily loss, peak-to-equity drawdown, open risk, EA status and reason trading is blocked.
6. Deliverables
- Full editable source code (.mq5) and compiled file (.ex5).
- No DLL, remote server, hidden dependency, account lock, expiry date or developer-controlled licence.
- Clean compilation with zero errors and zero warnings.
- Installation guide and explanation of every input parameter.
- Detailed journal messages for signals, rejected entries and risk-limit events.
7. Testing and validation
- Backtests for EURUSD and USDJPY from 01.01.2018 to the latest available date, using Every tick based on real ticks, variable spread, commission and realistic execution settings.
- Separate periods: development 2018-2023; out-of-sample validation 2024-latest.
- Provide HTML test reports, settings files and exact broker/data source used.
- Provide results with fixed 0.25% risk. Do not optimize lot size to manufacture profit.
- No acceptance requirement based on a promised monthly return.
- Demonstrate that daily 1% and total 5% risk blocks work in the Strategy Tester.
8. Acceptance
- Source code and files delivered through MQL5 Freelance.
- EA behavior matches this specification on a demo account and in Strategy Tester.
- Buyer receives one correction round for specification-related defects found within 14 days after delivery.
- Deadline: 10-14 calendar days.

EA Recovery Layer
30+ USD
Freelance Task — EA Recovery Layer Hello. I have a ready-made MQL5 EA. The signals, SL/TP and lot calculation should essentially not be touched. I need a recovery system added. I am not a programmer — below is how the robot should behave. What stays Entry only from an EA signal. Stop-loss is not a new signal.
