## Benefits of the New Structure

### 1. **MT5 Compatibility**
The new structure matches the official MetaTrader 5 file tree standard, making deployment straightforward.

### 2. **Easy Installation**
Simply copy the entire `MQL5/` folder to your MT5 Data Folder:
```
From: [Repository]/MQL5/
To:   [MT5 Data Folder]/MQL5/
```

### 3. **Better Organization**
- Expert Advisors are in `MQL5/Experts/`
- Configuration presets are in `MQL5/Presets/`
- All data files are in `MQL5/Files/`
- Educational materials are in `Docs/`

### 4. **Industry Best Practices**
Follows the standard used by professional MQL5 developers worldwide.

## How to Use the New Structure

### Installation Method 1: Copy Entire MQL5 Folder

1. **Locate your MT5 Data Folder:**
   - In MT5, go to `File → Open Data Folder`
   - This typically opens: `C:\Users\<USER>\AppData\Roaming\MetaQuotes\Terminal\<TERMINAL_ID>\`

2. **Copy the MQL5 folder:**
   ```
   Copy: [Repository]/MQL5/
   To:   [MT5 Data Folder]/MQL5/
   ```
   
3. **Merge/Overwrite when prompted:**
   - This will place EAs in the correct location
   - Presets will be available in MetaEditor
   - Files will be accessible to your EAs

4. **Compile the EAs:**
   - Open MetaEditor (F4 in MT5)
   - Navigate to `MQL5/Experts/`
   - Open any EA file
   - Press F7 to compile

### Installation Method 2: Selective Copy

If you only want specific files:

1. **For Expert Advisors:**
   ```
   Copy: [Repository]/MQL5/Experts/[EA_Name].mq5
   To:   [MT5 Data Folder]/MQL5/Experts/
   ```

2. **For Configuration Presets:**
   ```
   Copy: [Repository]/MQL5/Presets/[Preset_Name].set
   To:   [MT5 Data Folder]/MQL5/Presets/
   ```

3. **For Strategy Tester Configs:**
   ```
   Copy: [Repository]/MQL5/Files/[Config_Name].ini
   To:   [MT5 Data Folder]/MQL5/Files/
   ```

## Loading Configuration Presets

### Old Method (Still Works)
1. Attach EA to chart
2. In settings, click "Load"
3. Browse to preset file manually

### New Method (MT5 Standard)
1. Attach EA to chart
2. In settings, click "Load"
3. Presets from `MQL5/Presets/` appear in the list automatically
4. Select your preset (e.g., `ForexTrader_v3.2_Moderate.set`)
5. Click "OK"

## Strategy Tester Configuration

The `.ini` files in `MQL5/Files/` serve as reference configurations for Strategy Tester:

1. Open Strategy Tester (Ctrl+R)
2. Select your EA from the Expert list
3. Manually configure settings based on the `.ini` file in `MQL5/Files/`
4. Or load the corresponding `.set` file from `MQL5/Presets/`

## Frequently Asked Questions

### Q: Do I need to change anything in my existing MT5 installation?
**A:** No, this change only affects the repository structure. Your MT5 installation works the same way.

### Q: What if I already have the old files installed?
**A:** You can either:
- Keep using them (they'll continue to work)
- Replace them with files from the new structure
- Use the new structure for fresh installations

### Q: Are the EAs themselves changed?
**A:** No, the EA code is identical. Only the file locations changed.

### Q: Can I still use the old Config/ folder?
**A:** The `Config/` folder no longer exists in the repository. Use `MQL5/Presets/` instead.

### Q: Where are the educational PDFs now?
**A:** All educational materials are in the `Docs/` folder.

### Q: Where are the Previous Logs?
**A:** They're now in `MQL5/Files/Previous Logs/`.
