## 🎯 Overview
MAEA is a sophisticated trading robot that uses Exponential Moving Averages (EMAs) with dynamic border lines to identify trend-following opportunities. The EA includes multiple filters to ensure high-quality trade entries and comprehensive risk management to protect your account.
**Repository:** https://git.moreminimore.com/kunthawat/MAEA
**Platform:** MetaTrader 4
**Language:** MQL4
**Timezone:** Thailand (UTC+7)
## ✨ Features
### Core Strategy
- **5 Visual Indicator Lines:** 3 EMA lines + 2 dynamic Border Lines
- **Breakthrough Signals:** Entry when price breaks through EMA High/Low
- **Pullback Signals:** Enhanced lot sizing after pullback detection
- **Dynamic Lot Sizing:** 0.01 or 0.02 lots based on market behavior
- **Single Order Management:** Prevents over-trading
### Advanced Filters
- **Volume Filter:** Trade only when volume exceeds 20-bar average
- **Spread Filter:** Avoid high spread periods (max 30 points)
- **Multiple Timeframe Filter:** D1 trend confirmation (optional)
- **News Filter:** Avoid specific hours/days (Thailand timezone, optional)
### Risk Management
- **Take Profit:** Target in USD (default $5)
- **Stop Loss:** At dynamic Border Lines
- **Breakeven:** Move SL to entry at 100 points profit
- **Trailing Stop:** Trail by 100 points after breakeven
- **Max Drawdown Protection:** Stop trading at 10% drawdown
## 📊 Strategy Details
### Indicator System
#### EMA Lines (3 Base Lines)
All EMAs use period 30 with different price sources:
1. **EMA High** (Light Blue) - EMA of High prices
2. **EMA Medium** (Yellow) - EMA of Close prices
3. **EMA Low** (Orange) - EMA of Low prices
#### Border Lines (2 Dynamic Lines)
Calculated based on the range between EMAs:
1. **High Border** (Purple) = EMA High + (EMA Medium - EMA Low)
2. **Low Border** (Purple) = EMA Low - (EMA Medium - EMA Low)
**Example Calculation:**
```
EMA High = 3500
EMA Medium = 3400
EMA Low = 3300
Range = EMA Medium - EMA Low = 3400 - 3300 = 100
High Border = 3500 + 100 = 3600
Low Border = 3300 - 100 = 3200
```
### Signal Types
#### 1. Breakthrough Signal
- **Buy Signal:** Close price breaks above EMA High
- **Sell Signal:** Close price breaks below EMA Low
- **Purpose:** Triggers order opening
#### 2. Pullback Signal
- **Buy Pullback:** Price moves down to hit any line, then closes above the line
- **Sell Pullback:** Price moves up to hit any line, then closes below the line
- **Purpose:** Increases lot size when breakthrough occurs in same direction
- **Tracking:** Separate for buy and sell directions
### Order Management
- **Single Order:** Only one order at a time
- **Dynamic Lot Sizing:**
- 0.01 lot (no pullback before breakthrough)
- 0.02 lot (pullback occurred before breakthrough)
- **Stop Loss:** At Border Lines (Low Border for buys, High Border for sells)
- **Take Profit:** Target in USD (default $5)
- **Breakeven:** Move SL to entry at X points profit (default 100)
- **Trailing Stop:** Trail by X points after breakeven (default 100)

## 🔧 Troubleshooting
### EA Not Opening Orders
**Problem:** EA is attached but not opening any orders
**Solutions:**
1. Check if Auto Trading is enabled (green button in MT4 toolbar)
2. Verify EA is allowed in Tools → Options → Expert Advisors
3. Check if filters are too restrictive:
- Reduce `MaxSpread` if spread is too high
- Disable `UseMTFFilter` temporarily
- Disable `UseNewsFilter` temporarily
4. Verify account has sufficient margin
5. Check Experts tab for error messages
### Compilation Errors
**Problem:** EA fails to compile in MetaEditor
**Solutions:**
1. Ensure you're using MT4 (not MT5)
2. Check for missing brackets or semicolons
3. Verify all function names are spelled correctly
4. Update MetaEditor to latest version
### Incorrect Indicator Display
**Problem:** Lines not displaying correctly on chart
**Solutions:**
1. Ensure sufficient historical data (at least 50 bars)
2. Check if `EMAPeriod` is too high for available data
3. Refresh chart (right-click → Refresh)
4. Reattach EA to chart
### Orders Closing Prematurely
**Problem:** Orders closing too early or not reaching TP
**Solutions:**
1. Check if `TakeProfitUSD` is too low
2. Verify `MaxDrawdownPercent` is not too restrictive
3. Check if spread is causing SL hits
4. Review trade logs for closure reasons
### Drawdown Protection Triggering
**Problem:** EA stops trading due to drawdown
**Solutions:**
1. Increase `MaxDrawdownPercent` if too conservative
2. Wait for equity to recover above threshold
3. Review trading strategy and risk settings
4. Consider reducing lot sizes
### Timezone Issues
**Problem:** News filter not working at expected times
**Solutions:**
1. Verify your MT4 server timezone
2. Adjust `NewsAvoidHours` accordingly
3. Thailand timezone is UTC+7
4. Test with different hour values
### Performance Issues
**Problem:** EA slow or causing MT4 lag
**Solutions:**
1. Reduce `EMAPeriod` for faster calculations
2. Disable MTF filter if not needed
3. Close unnecessary charts and indicators
4. Check MT4 and computer performance
## 📝 Best Practices

# MAEA (Moving Average Expert Advisor) Implementation Plan
## Project Overview
- **Name**: MAEA
- **Type**: MQL4 Expert Advisor for MetaTrader 4
- **Strategy**: Advanced trend-following with EMA-based signals, multiple filters, and risk management
- **Repository**: https://git.moreminimore.com/kunthawat/MAEA
- **Timezone**: Thailand (UTC+7)
## Strategy Details
### 1. EMA Lines (3 Base Lines)
All EMAs use period 30 with different price sources:
- **EMA High**: EMA of High prices - Light Blue color
- **EMA Medium**: EMA of Close prices - Yellow color
- **EMA Low**: EMA of Low prices - Orange color
### 2. Border Lines (2 Dynamic Lines)
Calculated based on the range between EMAs:
- **High Border Line**: EMA High + (EMA Medium - EMA Low) - Purple color
- **Low Border Line**: EMA Low - (EMA Medium - EMA Low) - Purple color
**Example Calculation:**
```
EMA High = 3500
EMA Medium = 3400
EMA Low = 3300
Range = EMA Medium - EMA Low = 3400 - 3300 = 100
High Border = 3500 + 100 = 3600
Low Border = 3300 - 100 = 3200
```
### 3. Signal Types
#### 3.1 Breakthrough Signal
- **Buy Signal**: Close price breaks above EMA High
- **Sell Signal**: Close price breaks below EMA Low
- **Purpose**: Triggers order opening
#### 3.2 Pullback Signal
- **Definition**: Price hits a line and closes on the opposite side
- **Buy Pullback**: Price moves down to hit any line, then closes above the line
- **Sell Pullback**: Price moves up to hit any line, then closes below the line
- **Purpose**: Increases lot size when breakthrough occurs in the same direction
- **Tracking**: Separate tracking for buy and sell directions, resets when order opens
- **Lot Size Impact**:
- No pullback before breakthrough = 0.01 lot
- Pullback occurred before breakthrough = 0.02 lot
### 4. Order Opening Logic
- **Only one order at a time**
- **Lot Size**:
- 0.01 lot if no pullback occurred before breakthrough
- 0.02 lot if at least one pullback occurred before breakthrough in the same direction
- **Trigger**: Breakthrough signal only
- **Filters Applied**:
- Volume filter must pass
- Spread filter must pass
- MTF filter must pass (if enabled)
- News filter must pass (if enabled)
### 5. Risk Management
#### 5.1 Take Profit
- Target specified in USD (e.g., $5)
- Closes order when profit reaches target amount
#### 5.2 Stop Loss
- **Buy Orders**: SL at Low Border Line
- **Sell Orders**: SL at High Border Line
#### 5.3 Breakeven
- Triggered when profit reaches specified number of points (e.g., 100 points)
- Moves Stop Loss to breakeven (entry price)
#### 5.4 Trailing Stop
- Starts after breakeven is reached
- Trails Stop Loss by specified number of points from current price
- Default: 100 points trail distance
## Additional Filters and Features
### 6. Volume Filter
- **Calculation**: Average volume of last 20 bars
- **Condition**: Trade only when current volume > average volume
- **Purpose**: Ensures sufficient market activity
### 7. Multiple Timeframe (MTF) Filter
- **Timeframes**: H1 (trading) and D1 (filter)
- **Status**: Optional feature (can be turned on/off)
- **D1 Filter Logic**:
- If D1 close > D1 EMA High: Only buy orders allowed
- If D1 close < D1 EMA Low: Only sell orders allowed
- If D1 close between D1 EMA High and D1 EMA Low: No orders allowed
- **Behavior**: Order opens immediately when filter condition is met
### 8. Spread Filter
- **Purpose**: Avoid trading during high spread periods
- **Condition**: Only open orders when current spread <= maximum allowed spread
- **Default**: 30 points
### 9. Risk Management
- **Max Drawdown**: Maximum percentage drawdown allowed
- **Behavior**: Stop trading if drawdown exceeds limit
- **Recovery**: Resume trading when drawdown is below limit
### 10. News Filter
- **Purpose**: Avoid trading during high-impact news events
- **Implementation**: Avoid specific times (e.g., NFP, FOMC releases)
- **Timezone**: Thailand (UTC+7) - all times must be converted accordingly
- **Flexibility**: User can configure multiple time ranges to avoid
