Develop an Expert Advisor (EA) or suite of EAs for the MetaTrader 5 (MT5)

Project Requirements:

To develop a single Expert Advisor (EA) or a suite EAs for the MetaTrader 5 (MT5) platform, capable of trading multiple financial markets (Forex, Commodities, Crypto, Indices etc) using multiple diverse trading strategies. Intraday, Intraweek and Swing trading strategies. 

Ideally (if technically feasible) a single EA with the capability to switch between strategies is preferred, however separate EAs sharing a common base framework of core functionality would be acceptable. The project will be phased, focusing initially on producing the core functionality, then progressively adding the configurable strategy specific logic.

The fee payable is negotiable depending on the successful applicants preferred delivery methodology and understanding of the project requirements.

A summary of the core functionality to be included on the EA is shown below.

A comprehensive breakdown of each item will be provided to the successful applicant.

1. Data Handling & Backtesting: The EA must be capable of backtesting strategies using at least 10 years of historical price data. Data integrity and quality are paramount. The EA needs to handle a wide range of symbols across different asset classes (Forex, Commodities, Crypto, Indices). Symbol prefixes/suffixes and naming conventions must be managed correctly.

1. Risk Management: Stop Loss (SL): Mandatory SL for all trades.  Position Sizing: Flexible position sizing based on: Percentage of account equity, Percentage of account balance, Fixed currency value. Calculation of position based on SL size in pips and chosen risk percentage. Daily Loss Limit: Configurable maximum daily loss as a percentage of the account balance. Dynamic Risk Reduction: Configurable automatic reduction of risk/position size based on a predefined percentage of drawdown.
2. Trade Management: Moving risk to Break-Even (BE): Configurable BE trigger based on pips gained or the opening of a subsequent position on the same symbol (with commission consideration). Trailing Stop: Configurable trailing of stop loss. Multiple Take Profit (TP) Levels with the ability to close partial lots at each level. Trading Halt: Configurable profit target after which all trading ceases until manually resumed. Order Management: Robust handling of market, limit, and stop orders, including error handling and order modification/cancellation.
3. Trading Windows & Time Management:  Days of Week Filtering: Configurable option to enable/disable trading on specific days of the week (Mon-Sun). Time Zone Handling: Accurate handling of broker/market watch time relative to GMT/EST for time-based trade entries. Trading Session Filters: configurable time windows within a trading day, outside of which no new trades are initiated.
4. High Risk Event Management:  News Filters: EA to integrate with economic calendar APIs to avoid trading during high-impact news events. Time-Based blackouts: configurable hold periods pre or post-news events to ensure market stability before trading resumes.
5. Multi-Timeframe Analysis: Enable analysis across multiple timeframes (e.g., M5, H1, H4, D1) . To identify market structure, trend, Inefficiencies/FVGs to ensure alignment with higher or lower timeframes before placing trades
6. Market Structure Analysis: Identification of market structure, fractal highs and lows, and identification of Session Highs/Lows (Sydney, Tokyo, Frankfurt, London, New York AM/PM).
7. Error Handling and Recovery: Error Detection: Implement real-time detection for execution errors (e.g., trade rejections, network interruptions, broker downtime). Automatic Recovery: Develop logic to reinitialize the EA and resume trading after temporary disruptions. Logging: Maintain a detailed log of all actions, errors, and warnings to assist with troubleshooting.
8. Communication and Notifications: Alerts: Provide trade execution and error notifications via email, SMS, or push notifications. Integration: Enable compatibility with third-party monitoring tools like Myfxbook or Trade Explorer for performance tracking.
9. Indicator Library: Indicator Library: Provide built-in tools (e.g., Moving Averages, RSI, MACD, Bollinger Bands) while allowing user-defined custom indicators which will be replication of open source code Tradingview indicators.
10. User Interface and Customization: Develop an intuitive interface to: Adjust trading parameters. Monitor real-time trade performance. Access historical trade summaries. Provide presets for common trading scenarios and strategies.
11. Trade Execution : Strategy specific logic for entering trades based on indicators parameters, reversals following sweeps of fractal highs/lows etc
