MA TRIPLE ALERT INDICATOR - INSTALLATION & USAGE GUIDE
|
||||
=======================================================
|
||||
|
||||
OVERVIEW:
|
||||
This custom MT5 indicator displays three Moving Averages (MA 5, 8, and 13 periods)
|
||||
and generates buy/sell alerts with sound when specific conditions are met.
|
||||
|
||||
FEATURES:
|
||||
- Displays MA 5 (Red), MA 8 (Blue), and MA 13 (Green) on M5 chart
|
||||
- Buy Alert: When all 3 MAs are trending upward and properly separated
|
||||
- Sell Alert: When all 3 MAs are trending downward and properly separated
|
||||
- Sound alerts with customizable sound files
|
||||
- Visual alerts and notifications
|
||||
- Configurable parameters
|
||||
|
||||
INSTALLATION:
|
||||
1. Copy the MA_Triple_Alert.mq5 file to your MT5 data folder:
|
||||
[MT5 Installation]/MQL5/Indicators/
|
||||
|
||||
2. In MT5, go to Navigator → Indicators → Custom
|
||||
|
||||
3. Refresh or restart MT5 to see the new indicator
|
||||
|
||||
4. Drag and drop "MA Triple Alert" onto your M5 chart
|
||||
|
||||
USAGE:
|
||||
1. Open any currency pair on M5 timeframe
|
||||
2. Apply the MA Triple Alert indicator
|
||||
3. The indicator will display three colored moving averages:
|
||||
- Red line: MA 5
|
||||
- Blue line: MA 8
|
||||
- Green line: MA 13
|
||||
|
||||
ALERT CONDITIONS:
|
||||
|
||||
BUY SIGNAL:
|
||||
- All three MAs must be trending upward (rising for at least 2 consecutive periods)
|
||||
- MAs must be properly ordered: MA5 > MA8 > MA13
|
||||
- MAs must not be touching (minimum distance maintained)
|
||||
- Alert appears with sound notification
|
||||
|
||||
SELL SIGNAL:
|
||||
- All three MAs must be trending downward (falling for at least 2 consecutive periods)
|
||||
- MAs must be properly ordered: MA5 < MA8 < MA13
|
||||
- MAs must not be touching (minimum distance maintained)
|
||||
- Alert appears with sound notification
|
||||
|
||||
CUSTOMIZABLE PARAMETERS:
|
||||
- MA5 Period: Default 5
|
||||
- MA8 Period: Default 8
|
||||
- MA13 Period: Default 13
|
||||
- MA Method: SMA, EMA, SMMA, LWMA
|
||||
- Applied Price: Close, Open, High, Low, etc.
|
||||
- Minimum Distance: Points between MAs (default 5.0)
|
||||
- Enable Alerts: On/Off
|
||||
- Enable Sounds: On/Off
|
||||
- Buy Sound: alert.wav (customizable)
|
||||
- Sell Sound: alert2.wav (customizable)
|
||||
|
||||
SOUND FILES:
|
||||
Place custom sound files in: [MT5 Installation]/Sounds/
|
||||
Default sounds (alert.wav, alert2.wav) are included with MT5.
|
||||
|
||||
TROUBLESHOOTING:
|
||||
- If alerts don't work, check that "Allow DLL imports" and "Allow WebRequest" are enabled in Tools → Options → Expert Advisors
|
||||
- Ensure sound files exist in the Sounds folder
|
||||
- Check that notifications are enabled in Tools → Options → Notifications
|
||||
|
||||
NOTES:
|
||||
- Alerts are generated only on completed bars (not current forming bar)
|
||||
- Only one alert per bar to avoid spam
|
||||
- Indicator works best on M5 timeframe as requested
|
||||
- Can be applied to any currency pair or symbol
