Advanced Forex Trading Bot MQL5 EA for MetaTrader 5 (1)

Create a comprehensive, expert-level MQL5 Expert Advisor (EA) script for MetaTrader 5 that fully implements an advanced Forex trading bot as specified below.
### EA Requirements:
1. Technical Indicators Integration:
– Integrate multiple indicators:
– EMA
– RSI
– MACD
– Stochastic Oscillator
– Volume analysis
2. Risk Management:
– Implement adaptive risk management:
– Dynamic lot sizing as 1% of account balance
– Dynamic TP and SL, especially for minimum balances as low as $20
3. Time-Based Trading Restrictions:
– Confine trading to customizable New York session hours:
– `START_HOUR` to `END_HOUR`
### Market Sensing:
– Calculate the following:
– EMA with adjustable period (e.g., 20)
– RSI with adjustable period (e.g., 14) and defined thresholds:
– `OVERBOUGHT_THRESHOLD`
– `OVERSOLD_THRESHOLD`
– MACD histogram
– Stochastic Oscillator %K and %D
– Volume analysis
### Trade Execution Criteria:
– Buy Signals:
– Price is above EMA
– RSI is below `OVERSOLD_THRESHOLD`
– Bullish divergences on MACD and RSI
– Stochastic %K crosses above %D in oversold zone
– Volume supports upward momentum
– Sell Signals:
– Price is below EMA
– RSI is above `OVERBOUGHT_THRESHOLD`
– Bearish divergences on MACD and RSI
– Stochastic %K crosses below %D in overbought zone
– Volume confirms downward momentum
### Automatic Reversal Handling:
– Detect market reversals via divergences and indicator signals.
– Close existing positions and open reversed trades accordingly.
### News Event Management:
– Avoid opening new trade orders during scheduled news events affecting the symbol.
– Use `SymbolInfo()` or integrated MQL5 news APIs for detection.
### Global Variables Declaration:
Declare and initialize the following global variables at the top of the source file, clearly documented:
– `EMA_PERIOD` (integer, e.g., 20)
– `RSI_PERIOD` (integer, e.g., 14)
– `OVERBOUGHT_THRESHOLD` (float/integer, e.g., 70)
– `OVERSOLD_THRESHOLD` (float/integer, e.g., 30)
– `START_HOUR` (integer, New York session start hour in broker or specified timezone)
– `END_HOUR` (integer, session end hour)
– `MIN_ACCOUNT_BALANCE` (float, e.g., 20.0)
### EA Structure:
Organize the EA in a modular fashion with the following key lifecycle functions:
4. OnInit()
– Validate input parameters.
– Initialize and attach all indicators.
– Calculate starting lot size as 1% of current account balance.
5. OnDeinit()
– Properly detach indicators.
– Free all allocated resources.
6. News Detection Module
– Implement or integrate a method to detect scheduled news events affecting the symbol.
– Prevent trade openings during such news events within session hours.
7. OnTick() or Equivalent Compute Function
– Update indicator values upon each tick or new bar.
– Confirm current time is within defined session hours and no news event is active.
– Generate and validate buy/sell signals as per combined indicator criteria.
– Execute orders with proper lot sizing, adaptive SL, and TP.
– Handle existing trades and reversals.
8. Order Management Wrappers
– Robust wrappers for order sending and modification, including SL/TP management.
– Safe order closing functionality with error handling.
### Additional Requirements:
– Include comprehensive inline comments explaining all logic, parameters, and trading rationale.
– Provide guidance on optimal key parameters (e.g., EMA and RSI periods, thresholds) in comments.
– Ensure compatibility with MetaTrader 5 backtesting, including restricting data to the New York session.
– Support demo account operation.
– Apply robust error handling and input validations.
– Follow MQL5 coding standards and best practices.
### Output Format:
Provide a complete, well-structured `.mq5` source code file containing the fully implemented EA. Organize code modularly with distinct sections for:
– Initialization
– Indicator calculations
– Signal generation
– Order execution
– News detection
– Reversal handling
– Cleanup
Document all global variables and input parameters at the top of the file with clear, concise comments.
### Notes:
– Time-based restrictions must respect broker time or be configurable to align with New York session times.
– Dynamic lot sizing must adapt if account balance changes, always calculating 1% per trade.
– TP and SL levels must be calculated adaptively, ensuring risk management even for minimal balances like $20.
– News detection should be efficient and reliable, ideally using MQL5’s native functions or accessible APIs.
– Divergence detection logic must robustly identify reversals by comparing indicator trends against price action.
